Abstract:
The tensile yield strength, ultimate tensile strength, tensile modulus, ultimate flexural strength, flexural modulus, ultimate compressive strength, compressive modulus, impact strength, modulus of rigidity, and coefficient of thermal expansion were determined for several plastic materials at 77, -110, -200, -320, and -423 F. Materials tested included TFE and FEP Teflon, Kel-F, Mylar, and nylon, as well as fabric- and powder-reinforced TFE and FEP Teflon. The program included the determination of the effect of thermal treatment of certain of the materials on the crystallinity level, and the resultant effect on the mechanical properties. Author
