Abstract:

Chemistry and processing modifications of the polyDiels Alder polyimide PDA resin were performed to obtain structural composites suitable for 589K 600 deg F service. This work demonstrated that the PDA resin formulation developed under Contract NAS 3-17770 is suitable for service at 589K 600 deg F for up to 125 hours when used in combination with Hercules HTS graphite fiber. Sandwich panels were autoclave molded using PDAHTS skins and polyimideglass honeycomb core. Excellent adhesion between honeycomb core and the facing skins was demonstrated. Fabrication ease was demonstrated by autoclave molding three-quarter scale YF-12 wing panels. jg
