Abstract

A series of low and high velocity impact tests has been conducted on a wide range of cfrp laminates to examine the initiation and development of damage under these two widely differing loading conditions. For conditions of low velocity impact loading the size and shape of the target determines its energy-absorbing capability and therefore its impact response. High velocity impact loading by a fast moving projectile induces a localized form of target response and the level of damage incurred does not, therefore, appear to be governed by the areal size of the component. The effect of such loading on the residual tensile strength has also been assessed. High velocity impact loading by a small projectile is generally more detrimental to the integrity of a composite structure than low velocity drop-weight impact loading.
