Defect-Property Relationships in Composite Materials. Part IV.

Abstract

This report describes the results of an investigation of the nature of damage in two graphite-epoxy laminates under various loading histories, with special attention to the changes in mechanical properties caused by specific damage mechanisms. The results include several new findings, the development of unique investigative methods and some substantial deviations from common model predictions. The discovery of a 'characteristic damage state' is reported. (Author)
