Industrial commercial equipment and spare parts for the production of chemical fibers, fiberglass an

The structural properties of composite materials are derived primarily from the fiber reinforcement. Fiber types, their manufacture, their uses and the end-market applications in which they find most use are described. The fiber is the composite's primary source of the strength and stiffness. Fibers must be treated with chemicals, called sizings, that make them compatible with the intended matrix and ease processing. These rolls contain Tenax carbon fiber filament yarn, recently introduced by Toho Tenax Europe GmbH Wuppertal, Gemany with a new tailored sizing that makes the fibers compatible with thermoplastic resin matrices and useful in high-temperature composites applications.

This page requires that javascript be enabled for some elements to function correctly. The composites industry in the United States includes three manufacturing areas: Polymers, metals, and ceramics. Composites are classified according to their matrix phase. Materials within these categories are often called "advanced" if they combine the properties of high strength and high stiffness, low weight, corrosion resistance, and in some cases special electrical properties.

This combination of properties makes advanced composites very attractive for aircraft and aerospace structural parts. This chapter deals with a segment of the polymer composite industry known as advanced polymer matrix composites, or advanced composites. Since the reinforced plastics, or polymer matrix composite industry is much larger than the subject of this chapter, the term "advanced composites" is used here to define this special segment of the industry.

Information on this industry has been developed for use by OSHA field personnel to help them understand this new and growing technology. Advanced composites have been identified as an important growth sector in U. This identification has led to more use of these materials in existing facilities as well as an increase in the number of advanced composites manufacturing locations.

Field staff may expect to encounter composites more frequently in the course of their assignments. At the same time, much of the technology is new and not presented formally in secondary or undergraduate education.

Information is presented here on the technology as practiced in current operations. The technology of advanced composites manufacture is continually evolving, and field personnel will learn here what to expect in these processing facilities in the way of materials handled, manufacturing methods, machinery, potential worker exposures, and other relevant health and safety information. The information presented necessarily makes reference to industrial hygiene and safe work practices, but this manual is not intended to provide comprehensive guidelines for assessing compliance with regulations.

Much of the terminology used in this manual is peculiar to the composites industry, and for this reason a glossary of terms has been provided in Appendix III Polymer-matrix composites manufacturing is a multibillion dollar industry in the U.

Composite products range from skateboards to components of the space shuttle. The industry can be generally divided into two basic segments, industrial composites and advanced composites. Several of the composites manufacturing processes are common to both segments. The two basic segments are described below. The industrial composites industry has been in place for over 40 years in the U.

This large industry utilizes various resin systems including polyester, epoxy, and other specialty resins. These materials, along with a catalyst or curing agent and some type of fiber reinforcement typically glass fibers are used in the production of a wide spectrum of industrial components and consumer goods: boats, piping, auto bodies, and a variety of other parts and components. The feature common to all composite processes is the combining of a resin, a curing agent, some type of reinforcing fiber, and in some cases a solvent.

Typically, heat and pressure are used to shape and "cure" the mixture into a finished part. In composites, the resin acts to hold the fibers together and protect them, and to transfer the load to the fibers in the fabricated composite part.

The curing agent, also known as hardener, acts as a catalyst and helps in curing the resin to a hard plastic. The reinforcing fiber imparts strength and other required properties to the composite. Solvents may serve three purposes:. Diagrams of the major processes used in the advanced composites industry are provided in Section A of this chapter. The processes vary widely in type of equipment and potential worker exposure.

Several of the processes are automated; however, some are manual and require worker contact with the part during manufacture. The basic process types are described below.

The advanced composite processes are discussed in more detail in Section V of this chapter. Seven manufacturing processes are covered, along with two preliminary processes and two finishing processes. The number and variety of processes should give some indication of the wide spectrum of workplaces likely to be encountered by field personnel.

Potential worker exposure obviously will also vary widely, depending on the size and type of process being used. Since the advanced composite industry is relatively new and still developing, other processes may be developing or changing to meet new performance requirements.

Advanced composites exhibit desirable physical and chemical properties that include light weight coupled with high stiffness and strength along the direction of the reinforcing fiber, dimensional stability, temperature and chemical resistance, flex performance, and relatively easy processing.

Advanced composites are replacing metal components in many uses, particularly in the aerospace industry. The resin systems used to manufacture advanced composites are of two basic types: thermosetting and thermoplastic.

Thermosetting resins predominate today, while thermoplastics have only a minor role in advanced composites manufacture. Thermoplastics currently represent a relatively small part of the PMC industry.

They are typically supplied as nonreactive solids no chemical reaction occurs during processing and require only heat and pressure to form the finished part. Unlike the thermosets, the thermoplastics can usually be reheated and reformed into another shape, if desired.

Several solvents may be used in any one composite process. One or more may be introduced as part of the resin or curing agent, while another may be a part of the manufacturing process. Still another may be used for cleanup. Thus the hazard information for all products used in the process must be considered when evaluating potential exposures. Composite residues are often difficult to clean from operation equipment and molds.

Various solvents have been used for cleaning, with varying degrees of success. Solvents in the workplace may be found in several areas:. A brief description of each process is given, followed by a basic diagram. Resin formulation consists of mixing epoxy or other resins with other ingredients to achieve desired performance parameters.

These ingredients may be curing agents, accelerators, reactive diluents, pigments, etc. Prepregging involves the application of formulated resin products, in solution or molten form, to a reinforcement such as carbon, fiberglass or aramid fiber or cloth. The reinforcement is saturated by dipping through the liquid resin solution form, see Figure III or by being impregnated through heat and pressure hot melt form, see Figure III In the filament wet winding process, continuous fiber reinforcement materials are drawn through a container of resin mixture Figure III and formed onto a rotating mandrel to achieve the desired shape.

After winding, the part is cured in an oven. A prepreg product is laid down and formed to the desired shape Figure III Several layers may be required. After forming, the lay-up assembly is moved to an autoclave for cure under heat, vacuum and pressure. In this process, the prepreg tape material is fed through an automated tape application machine robot.

The tape is applied across the surface of a mold in multiple layers by the preprogrammed robot Figure III Resin transfer molding is used when parts with two smooth surfaces are required or when a low-pressure molding process is advantageous.

Fiber reinforcement fabric or mat is laid by hand into a mold and resin mixture is poured or injected into the mold cavity. The part is then cured under heat and pressure Figure III In the pultrusion process, continuous roving strands are pulled from a creel through a strand-tensioning device into a resin bath. The coated strands are then passed through a heated die where curing occurs. The continuous cured part, usually a rod or similar shape, is then cut to the desired length Figure III One of the older plastics processes, injection molding is also the most closed process.

It is not normally used in PMC processes due to fiber damage in the plasticating barrel. Thermoplastic granules are fed via a hopper into a screw-like plasticating barrel where melting occurs Figure III The melted plastic is injected into a heated mold where the part is formed.

This process is often fully automated. Most parts made by hand lay-up or automated tape lay-up must be cured by a combination of heat, pressure, vacuum, and inert atmosphere.

To achieve proper cure, the part is placed into a plastic bag inside an autoclave Figure III A vacuum is applied to the bag to remove air and volatile products. Heat and pressure are applied for curing. Usually an inert atmosphere is provided inside the autoclave through the introduction of nitrogen or carbon dioxide. Exotherms may occur if the curing step is not done properly. This may involve drilling, sanding, grinding, or other manual touch-up work.

These processes vary widely, depending on the size of the finished part and the amount of finishing work required. Repair of damaged PMC parts is frequently required. The process may consist of several steps including cutting out of the damaged material, depainting of the surface to be repaired, patching and sanding of the damaged area, and repainting of the repaired area. Potential health hazards associated with the use of advanced composites Table III can be controlled through the implementation of an effective industrial hygiene program.

Use of safe work practices, engineering controls, and proper personal protective equipment depends upon an appreciation of health hazard information for a safe work environment. High molecular weight is generally associated with decreased volatility.

In an epoxy system, the resin components have very low vapor pressures and they are not present as a volatilized airborne hazard. Most of the reinforcing materials used in the industry have the potential to cause eye, skin, and upper respiratory tract irritation as a result of the mechanical-irritant properties of the fibers.

The potential synergism has not been clearly defined. The chemical irritation caused by resins can compound the mechanical irritation caused by the fibers. However, the PAN-based carbon fibers are the predominant form in use today. It is important to ascertain which type of carbon-fiber precursor is used in order to evaluate the hazards. Pitch-based carbon fibers may be associated with an increased risk of skin cancer, although the evidence is weak.

PAN-based carbon fibers did not cause tumors when the same test was conducted. Standard mutagenicity tests conducted on PAN-based carbon fibers were negative. The principal hazards of carbon-fiber handling are mechanical irritation and abrasion similar to that of glass fibers.

Introducing 3D Printed Inconel 625

There are numerous methods for fabricating composite components. Selection of a method for a particular part, therefore, will depend on the materials, the part design and end-use or application. Here's a guide to selection. Vacuum infusion has found significant application in boatbuilding, because it permits fabricators to infuse entire hulls, deck structures and planar contoured parts in a single step. But aerospace structures, another group of often large parts, are also being developed using vacuum infusion processes. Fiber reinforcements are placed in a one-sided mold, and a cover typically a plastic bagging film is placed over the top to form a vacuum-tight seal. The resin typically enters the structure through strategically placed ports and feed lines like these in use during infusion of an outrigger hull for the Ocean Eagle 43 is a light ocean patrol vessel built in by by Chantier Naval H2X La Ciotat, France for shipbuilder CMN Paris and Cherbourg, France. Resin is drawn by vacuum through the reinforcements by means of a series of designed-in channels that facilitate fiber wetout. Because it does not require high heat or pressure, vacuum infusion can be done with relatively low-cost tooling, making it possible to inexpensively produce large, complex parts.

High Performance Carbon Fibers

Also called graphite fiber or carbon graphite, carbon fiber consists of very thin strands of the element carbon. These fibers have high tensile strength and are extremely strong for their size. In fact, one form of carbon fiber—the carbon nanotube —is considered the strongest material available. Carbon fiber applications include construction, engineering, aerospace, high-performance vehicles, sporting equipment, and musical instruments.

The automotive industry uses a tremendous number of materials to build cars and other vehicles, including iron, aluminum, plastic steel, glass, rubber, petroleum products, copper, steel and others.


Fiberglass American English , or fibreglass Commonwealth English is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat , or woven into a fabric. The plastic matrix may be a thermoset polymer matrix —most often based on thermosetting polymers such as epoxy , polyester resin , or vinylester —or a thermoplastic.

Manufacturing is no longer simply about making physical products. Changes in consumer demand, the nature of products, the economics of production, and the economics of the supply chain have led to a fundamental shift in the way companies do business. Customers demand personalization and customization as the line between consumer and creator continues to blur. As technology continues to advance exponentially, barriers to entry, commercialization, and learning are eroding. New market entrants with access to new tools can operate at much smaller scale, enabling them to create offerings once the sole province of major incumbents. While large-scale production will always dominate some segments of the value chain, innovative manufacturing models—distributed small-scale local manufacturing, loosely coupled manufacturing ecosystems, and agile manufacturing—are arising to take advantage of these new opportunities.
