Anelastic Deformation of a Thermoplastic-Matrix Fiber Composite at Elevated Temperature. Part 2. Time-Temperature Dependent Matrix Behavior.

摘要

This is the second in a series of papers on the anelastic deformation behavior of a thermoplastic polymer-matrix/graphite-fiber composite. In the previous paper we reported the structural characterization of the neat resin; in this paper the time and temperature dependent mechanical properties of the resin, are addressed as a function of processing (structure) history. Such a study is needed for understanding matrix-dominated properties of the composite and to guide the improvement and application of the composite system. The time-temperature dependent properties of matrix and composite are examined in detail since this class of composites are being considered for elevated-temperature applications.
