Cure Shrinkage Behavior of Polymer Matrix Composite according to Degree of Cure

Composites Research, 2014
ABSTRACT: Cure shrinkage during cure process of polymer matrix composites develope residual stress that causesome structural deformation, such as spring-in, spring-out and warpage. The carbon/epoxy prepreg used in this studyis Hexply M21EV/34%/UD268NFS/IMA-12K supplied by Hexcel corp.
