High Performance Composites and Adhesives for V/STOL Aircraft.

Abstract

An interdisciplinary program has been undertaken to address the composite and adhesive materials requirements of V/STOL aircraft. The primary tasks are to develop and characterize high modulus, high toughness resins with use temperatures of 350 F to 450 F or higher, to develop fabrication technology for newly developed resin matrices for graphite-fiber reinforced composites, to develop composite failure criteria for design optimization and to establish appropriate quality control parameters. The principal accomplishments to date have been to demonstrate (a) the variation in mechanical properties obtainable by the molecular tailoring of polyphthalocyanine resins, (b) the effectiveness of NMR spectroscopy for chemical characterization of resins of complex composition, (c) the viability of resin cure using ionizing radiation, and (d) the development of a unique approach to determining failure criteria for flaw growth in resin matrix composites.
