Abstract
Abstract A HIGH-STRENGTH HIGH-TEMPERATURE, ABLATION-RESISTANT COMPOSITE OR STRUCTURE IS FORMED OF FIBROUS CARBON OR GRAPHITE BONDED IN A CARBONIZED BINER. THE FIBROUS STRUCTURE IS FORMED OF SMALL, STRAIGHT, CARBONACEOUS FIBERS OF VIRTUALLY UNIFORM LENGTH WHICH ARE ADMIXED WITH A CARBONIZABLE BINDER AND SPRAYED ONTO A SUITABLE SURFACE. THE SPRAYED ADMIXTURE IS THEN HEATED SUFFICIENTLY TO CARBONIZE OR GRAPHITIZE THE BINDER FOR FORMING A HIGH-STRENGTH, CARBONACEOUS STURCUTRE OF DESIRED CONFIGURATION. THE FIBERS IN THE CARBONACEOUS STRUCTURE ARE RANDOMLY ORIENTED AND UNIFORMLY DISPERSED TO PROVIDE THE FIBROUS STRUCTURE WITH THE AFOREMENTIONED PROPERTIES.
