Abstract

A composite material comprising: a composite substrate comprising a polymeric matrix with fibre reinforcement; and a conductive layer comprising one or more conductive filaments embedded in a polymeric matrix. The conductive filaments provide a conductive surface layer onto which a further coating can be directly deposited. The conductivity of the layer is particular useful for some coating techniques such as electroplating which require the target to be conductive, but the conductive surface (more preferably a metal surface) also provides a good bonding layer for other deposition processes such as HVOF (High Velocity Oxygen Fuel) and plasma spraying techniques. Advantageously the conductive layer is provided directly on the composite substrate without the need for any further intermediate layers such as have been used previously.
