Abstract : High temperature adhesive systems are sought containing integral electrical resistance heating elements for use in the fabrication of honeycomb sandwich structures, utilizing a metal core. Examination and testing of several types of heating elements, including metallic wire and ribbon, led to the conclusion that carbon fabric has the greatest promise for this application. Seven different resin systems, including polyimides, polybenzimidazole, and amide-imides were mofified in an attempt to produce a satisfactory heater-adhesive combination. Preliminary studies involving honeycomb sandwich structures have shown that a problem area exists due to electrical shorting during curing operation.
