New insulating composite systems were fabricated for solid fuel rocket engine. The basic structure consisted of an outer refractory surface of multilayer construction and a porous inorganic thermal barrier. These were adhesively bonded to the sub trate plastics. Multilayer Ni-zirconia coatings applied by flame and plasma spray techniques were used as the principal erosion resistant surfaces. Composite structures were investigated in test firings of a solid fuel rocket. These firings showed that the c mposite structures of plastic and a thermal barrier offered improved behavior in tests up to 20 seconds. Various materials were tested as possible mechanical reinforcements for the insulating layer. Metal honeycombs were selecte for use in the fabrication studies. (Author)
