Titel
High-rate in-plane shear testing of CFRP using the Split Hopkinson tension bar
Abstract
The high-rate in-plane shear properties of IM7/8552 composite material was investigated using a Split Hopkinson Tension Bar featuring constant impedance mountings in order to maximize the quality of the load signal. The in-plane shear response up to failure was evaluated using Digital Image Correlation (DIC) and correction terms for fiber rotation. The in-plane shear strength was found to increase from 80 MPa for quasi-static loading conditions to 175 MPa for a strain rate of 2600 s-1.
