Influence of Cure Shrinkage on Process-Induced Sum and Deformation in ThickThermosetting Composites

摘要

The development of residual sum is strongly influenced by processing history.Residual stress can have a significant effect on the mechanics and performance of composite structures by inducing warpage or initiating matrix cracks and delaminations. A fundamental study of the complex relationship between processing of thermosetting composites and residual sum has ban conducted by the authors (Bogetti and Gillespie 1989, 1990a, 1990b). A cure simulation analysis coupled to
