Production of fiber reinforced composites
Abstract
Abstract AN IMPROVED PROCESS IS PROVIDED FOR THE FORMATION OF ESENTIALLY SOLID FIBER REINFORCED COMPOSITE BODIES. THE PROCESS IS PARTICULARLY SUITED FOR THE FORMATION OF COMPOSITE BODIES HAVING A HIGH VOLUME OF FIBROUS REINFORCING MEDIUM (E.G. CARBONACEOUS FILAMENTS) DISTRIBUTED IN A MATRIX (E.G. AN EPOXY RESIN) IN A HIGHLY ORIENTED RELATIONSHIP. IN THE PRODUCTION OF COMPOSITE BODIES THE FIBROUS REINFORCING MEDIUM WHILE PRESENT WITHIN A HEAT-SHRINKABLE MOLD IS COMPACTED BY THE APPLICATION OF HEAT AND A FLOWABLE MATRIX-FORMING MATERIAL SUBSEQUENTLY IS INTRODUCED INTO THE MOLD AND SOLIDIFIED TO A MOLDABLE B-STAGE OR RIGID C-STAGE CONSISTENCY. THE ESSENTIALLY SOLID COMPOSITE BODIES FORMED ACCORDING TO THE INVENTION ARE USEFUL IN THE FORMATION OF HIGH PERFORMANCE STRUCTURAL ELEMENTS OR AS HIGH PERFORMANCE STRUCTURAL ELEMENTS.
