On the bearing strengths of cfrp laminates

Abstract Bearing strength measurements have been made on 0° ±45°, 0° 90° and 90° ±45° cfrp laminates made from three different fibre/resin systems; HTS/914, XAS/914 and HTS/HC 3501. Equations have been derived for predicting the ultimate bearing strengths of constrained pin-loaded holes using a semi-empirical approach, and considering the physical conditions governing failure at the hole edge. Experimental results are presented and these show good agreement with those predicted for each of the laminate configurations and fibre/resin systems used.
