Abstract

A fibre reinforced polymer (FRP) composite structure incorporates a woven preform containing tows of carbon or other advanced fibres and wires of shape memory alloy (SMA). The SMA wires are capable of absorbing much larger amounts of strain energy than the conventional components of FRP composites and hence enhance the impact resistance of the structure. The woven form incorporates the SMA into the structure in an optimum manner in terms of handling and performance.
