摘要：

Static indentation and dropweight impact tests have been performed on three pultruded sections of glass fibre/polyester resin laminates using an instrumented test rig. Damage in the form of cracking of the lower surface has been related to permanent indentation of the contact surface. This damage relationship is independent of flexural stiffness for static loading but dependent on flexural stiffness for impact conditions. Backface cracking has been assessed in terms of residual compression and the results indicate that static loading is more severe than impact. (C) 1998 Elsevier Science Ltd. All rights reserved.
