Attempts made to improve the acoustical properties of low density Fiberfrax foam, an aircraft insulation material, are reported. Chacterizations were also made of the physical and thermal properties. Two methods, optimization of fiber blend composition and modification of the foam fabrication process, were examined as possible means of improving foam acoustics. Flame impingement tests were also made; results show performance was satisfactory. (Author)
