This invention provides a seal assembly for sealing a gap between first and second relatively movable members. The first member is provided with a sealing surface, and the second member is provided with a sacrificial abradable layer that is positioned opposite the sealing surface of the first member. When the seal assembly is in operation the sealing surface of the first member moves relative to, and abrades, the abradable layer of the second member thereby maintaining a seal between the members. The present invention is characterised in that, the second member and the abradable layer comprise the same composite material. The second member and the abradable layer may be co-cured together during manufacture.
