Advances in gas turbine technology depend in large measure upon advances in materials technology. Arbitrary stringent criteria for room temperature spefific strengths and moduli and for 2000 F, 1000-hr stress-rupture strength were chosen for design goals. Required fiber properties to meet these criteria were calculated for fiber and matrix material combinations of widely ranging densities. It was demonstrated, on a first approximation basis, that numerous composite materials with specific tensile or stress-rupture strengths, and specific moduli superior to those of conventional materials can be “designed” from fiber and matrix materials available today.
