Advanced Composite Engine Design Allowables Program.
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)
