Abstract
THIS PROPOSAL PRESENTS A PROGRAM FOR THE STRUCTURAL EVALUATIONS OF COMPOSITE LAMINATES CONTAINING HIGH STRAIN GRAPHITE FIBERS AND COMPATIBLE RESIN SYSTEMS. THE FAILURE ANALYSIS METHODOLOGY WILL INVOLVE THE DEVELOPMENT OF LAMINA ALLOWABLES BASED ON FIBER AND MATRIX PROPERTIES. THE LAMINATE FAILURE ANALYSES ARE TO BE CONDUCTED BY ACCOUNTING FOR SEQUENTIAL FAILURES IN THE VARIOUS PLIES. PARAMETRIC STUDIES WILL BE CONDUCTED TO IDENTIFY THE CRITICAL REQUIREMENTS WHICH MUST BE MET BY THE CONSTITUENT FIBER AND MATRIX TO FULLY UTILIZE THE HIGH STRAIN FIBER CAPABILITY. THE FAILURE ANALYSIS WILL ACCOUNT FOR THE DIFFERENT FAILURE MECHANISMS OF A UNI-DIRECTIONAL COMPOSITE SO THAT THE EFFECTS OF HIGH STRAIN FIBERS ON FAILURE MECHANISMS CAN BE STUDIED. THE TECHNICAL EFFORT WILL THEN BE EXTENDED TO THE PREDICTION OF THE INITIATION OF FAILURE IN LAMINATES CONTAINING STRESS CONCENTRATIONS TO IDENTIFY THE POTENTIAL OF THESE FIBERS IN REALISTIC CONFIGURATIONS.
