High Temperature Resins for Composites. Part II.
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). This second report details the last portion of the technical effort. The first portion is described in AFML-TR-77-188. Celion 3000 by Celion 1000 (30 by 5) unidirectional fabric was selected for use with Thermid 600. Several feet of hot melt Thermid 600/Celion prepreg were fabricated. This prepreg was found to easily be press molded into composites at 485 F. The mechanical strength of these composite after postcure is described up to 600 F. The melt processability and gel times of ATQ polymers is very similar to the melt processability of Thermid 600.
