Assessment of Microdamage Development during Tensile Loading of Graphite/Epoxy Laminates.

Abstract

The present work examines in a systematic way the development of microdamage in several laminates of graphite/epoxy material during quasi-static tensile loading. Emphasis is placed upon discriminating and quantifying matrix and fiber damage. Penetrant-enhanced X-ray radiography and edge replication were used to map the progression of matrix damage. The recently developed technique of specimen deply was used to follow the progression of fiber fracture. By complementary application of these destructive and nondestructive techniques a more complete and coherent picture of microdamage was developed.
