Experimental study of strain-rate-dependent behavior of carbon/epoxy composite

The strain rate dependent behavior of IM7/977-2 carbon/epoxy matrix composite in tension is studied by testing the resin and various laminate configurations at different strain rates. Tensile tests have been conducted with a hydraulic machine at quasi-static strain rates of approximately 10−5 s−1 and intermediate strain rates of about 1 s−1. Tensile high strain rate tests have been conducted with the tensile split Hopkinson bar technique at...
