Abstract:

This report covers the work performed in determining material properties of the advanced composite materials selected for fan blade development and intermediate case development for a supersonic gas turbine. Four composite systems were evaluated in support of fan blade development activities BORON-Skybond 703, boron-P13N, HMG50-P13N, and BORSIC -6061 aluminum. The polyimide systems were investigated at temperatures from -65 F to 500 F and the BORSIC aluminum system from -65 F to 600 F. The investigation included determinations of both short-time and time-dependent properties. Three composite systems were evaluated in support of the intermediate case technology development boron-P13N, HMS GRAPHITE-P13N, and HTS graphite-P13N. Properties for the first two systems were determined at 70 F, 450 F, and 600 F and for the third system at 70 F and 600 F. The properties determined were longitudinal flexure, longitudinal and transverse tension, interlaminar shear, and coefficient of thermal expansion. Author, modified-PL
