Viscoelastic and cyclic compaction response of prepregs tested under isothermal temperatures and various compaction speeds

Viscoelastic compaction/relaxation and cyclic compaction studies of uncured prepregs are of importance to understand the process parameters, such as mold closing forces and speed and the clamping force required to maintain a given thickness during molding, and so forth, for many composites manufacturing processes, including compression molding. In this study, viscoelastic compaction/relaxation, and multi‐cycle‐compaction tests were performed on...
