Abstract : The consideration of glass as a high temperature thermoplastic has resulted in a new composite that can be used at temperatures up to 875 K with mechanical properties equal or superior to graphite fiber reinforced epoxy composites whose upper use temperature is between 420 and 470 K or graphite fiber reinforced aluminum composites with an upper use temperature of 600 K. Furthermore, this new composite has superior thermal and environmental stability in comparison to these other composites. This composite system consists of graphite fiber, uniaxially or biaxially, reinforced borosilicate glass. The mechanical and thermal properties of such a graphite fiber reinforced glass composite are described, and the system is shown to offer promise as a high performance structural material. jg p2
