    Abstract

    In two earlier papers [1,2], we reported that the simulated flywheel service environment (vacuum and 75°C) had negligible effect on the mechanical properties of a Kevlar 49/epoxy composite except for the cracking of plies in cross-ply laminates resulting from high curing stresses and low transverse strength. To ascertain this excellent property retention, we further tested individual fibers in similar environments. The results on strength and failure mode of these individual fibers are presented in this paper.
