Effects of Materials and Processes Defects on the Compression Properties of Advanced Composites.

Abstract

This report discusses a program that attempts to quantify the severity of materials-related or process-induced defects in As/3501-6 graphite/epoxy laminates. Emphasis is laid on porosity as the primary defect under study, though a limited number of tests on specimens with imbedded delaminations was also carried out. The primary laminate under study is a 3O-ply laminate with a layup similar to a highly-loaded portion of the F/A-l8A vertical stabilizer skin. Grimes and Adams have generated the basic properties under compressive loading situations, for defect-free AS /3501-6 laminates including some basic laminates and the 30-ply laminate. The program discussed in this report adopts the above-mentioned AS/350l-6 laminates for a test program that aims at quantifying the effect of materials- and process-induced defects. (MM)
