The chassis is made from a 1/4 in. sheet of either ABS or TPO vacuum formed into a tub and reinforced with reinforced pultruded glass fiber-TS polyester plastic tubing. The hood and other products are being made from a 20 mm thick sandwich of thermo-formed PPO-alloy skins, glass fabric infused with thermosetting vinyl ester, and a urethane foam core. The bumper and front fascia is thermoformed from a polyolefin elastomer sheet with an UV-resistant cap layer of DuPont s Tediar PVF film. The dash and... 

This chapter will deal with the chemistry and applications of epoxies, phenolics, urethanes, and a variety of current vogue high-temperature polymers. Applications in fiber-reinforced plastics will be discussed in the individual sections on resin chemistry where appropriate. Separate sections will deal with adhesives and sealants. Adhesives are most important because, as early history demonstrates, they led the way to the application of resins in aerospace. A section is also included on silicone and polysulfide sealants. Although these materials are elastomers rather than resins, no discussion of aerospace polymers would be complete without some mention. Some major thermosetting polymers have been omitted from this review. Among these are the unsaturated polyesters, melamines, ureas, and the vinyl esters. Although these products do find their way into aerospace applications, the uses are so small that a detailed discussion is not warranted. 

Polyesters refer to the various polymers in which the backbones are formed by the esterification condensation of polyfunctional alcohols and acids. Polyesters chemically are divided into two types saturated and unsaturated polyesters. Saturated polyesters refer to the polyesters with saturated backbones. Such polyesters are unreactive and consist of low-molecular-weight liquids which are used as plasticizers and reactants in forming urethane polymers and linear, high-molecular-weight thermoplastics such as polyethylene terephthal-ate. Unsaturated polyesters refer to the polyesters with vinyl unsaturation. Most of them are used in reinforced plastics and are widely used as economically class resins.

Thermoplastic polyesters include unfilled or reinforced grades of polycarbonates, polyethylene terephthalate, polybutylene terephthalate and blends and copolymers of these plastics. Cyanoacrylates and urethanes bond well to these materials. UV-cured acrylics are suitable for transparent plastics such as polycarbonate.
