An Experimental Method for Dynamic Properties of Composites at Interior Ballistic Rates of Loading.

Abstract

An experimental method that uses an airgun system was developed to investigate the dynamic response of materials in a gun launch environment. An energy absorbing test fixture was designed to generate the desired loading conditions in the specimen as it decelerated the gun-launched projectile. Methods of data acquisition and reduction were developed using a streak camera and a film digitization technique. The system was calibrated and verified by testing aluminum samples, and fairly good results were obtained. The technique was then applied to a polymer composite laminate having a particular layup construction of interest. Strain rate effects on the compressive strength were observed at the interior ballistic rates of loading. (MM)
