High Temperature Resins for Composites

Abstract:

Three Air Force resin systems were investigated for their potential to achieve their individual merits in graphite composites. The three resins were Thermid 600, acetylene-terminated quinoxalines ATQ, and polyimidazoquinazoline PIQ. Hot-melt prepreg techniques were investigated and found to give higher quality prepregs lower volatile content than solution techniques for the Thermid 600. High quality composites were produced from prepregs produced by both methods. The ATQ oligomer was synthesized, solution prepregged, and then processed into graphite composites. PIQ was synthesized and hot-melt prepregged, and did not produce a high quality laminate. This is probably due to fiber or fiber-finish instability at the high cure temperatures required. Celion 3000 was selected from thermal oxidative tests carried out on several fibers at 700 deg F.
