Abstract : Some physical properties were determined on a low-density phenolic-nylon that was both nondegraded (virgin) and thermally degraded (charred). The low-density phenolic-nylon was a molded composite consisting of 25% phenolic resin, 35% phenolic Microballoons, and 40% powdered nylon. The material was thermally charred in an arc tunnel. Thermal conductivity was determined for various high and low temperatures. The permeability of both the virgin and charred material was obtained at low pressure drops across the specimen with helium and nitrogen used as the permeating gases. Strength was determines at various temperatures and pressures.
