Abstract
Matrix cracks and their effect on ultimate laminate strength in [0/90]s type graphite/epoxy laminates were investigated. Crack saturation density was found ex perimentally and compared with that predicted using a finite element analysis. Good agreement was found. To estimate the effect of the 90°-ply cracks on the load capacity of adjacent 0°-plies, a soft but tough adhesive film was placed along the interfaces in some laminates to isolate the effect of the matrix cracks. The use of adhesive layers in [0/908/0] and [904/02/904] laminates raised the laminate strengths by about 30%.Keywords
