This paper describes experiments to evaluate the viscoelastic properties of a thermoplastic, K3B (DuPont Corp.) which is considered as a candidate matrix for advanced fiber reinforced composites as might find application in the proposed high speed civil transport (HSCT). The test program included both constant strain rate tension tests and stress relaxation experiments. The relatively high glass transition temperature of this polymer and the brittle character of its behavior at temperatures well below the glass transition necessitated the use of unique test grips and extensiometry. K3B proved to exhibit linearly viscoelastic characteristics at and below 1 % strain and the relaxation data were amenable to master curve formation through only horizontal shifting. Consistency checks between the relaxation and the constant strain rate tensile data were effected.
