Abstract

Experiments have been performed to investigate the damage mechanisms and failure modes of crossply CFRP laminates under pure tensile and pure compressive loading. Unnotched and notched crossply laminates were tested. Extensive splitting was observed prior to specimen failure for both pure tension and pure compression cases. This mode of damage was seen to have a profound effect on the strength and notch sensitivities of the specimens. Although notches were observed to greatly weaken the laminate, the reduction in strength was not proportional to the inverse of the stress concentration factor presented by the notch geometry. This was explained by the damage that had developed around the notch tips that acted to reduce the stress concentration at hand, and effectively strengthen the laminate specimens.
