Post-Buckling, Damage Tolerance and Manufacturing Techniques for Advanced Composite Materials.

Abstract

This report describes a basic research program to study the post-buckling, the damage tolerance, and manufacturing techniques for various built-up, composite structures. Five separate investigations are briefly summarized here. These dealt with (1) buckling and failure studies of integrally stiffened graphite/epoxy panels, (2) finite element and experimental studies of buckling of laminated thin-wall, graphite structures, (3) damage tolerance of pressurized graphite/epoxy cylinders flawed with slits and holes, and (5) damage tolerance of graphite/epoxy cylinders with a high strain-to-failure matrix system. These studies help provide information on the use of graphite/epoxy composites in heavily loaded structures. For more thorough descriptions and details, refer to the individual reports cited here. Keywords: Advanced composites, Post buckling, Damage tolerance, Pressurized cylinders.
