摘要：A composite component such as a blade or vane of a gas turbine enginecomprises a body 2 and an erosion-resistant layer 4. The body 2 comprises a fibrereinforcement in a resin matrix, and the erosion-resistant layer 4 comprises a 3-D woven
fabric element which is also resin-impregnated. The woven fabric element is made from athermoplastics material such as PEEK, and may be thicker at the leading edge 6 of thecomponent than at pressure and suction surfaces 8, 10. The component may bemanufactured in a laying-up process in which the woven fabric element of the erosion-resistant layer 4 is placed in a mould with the resin-impregnated fibre reinforcement ofthe body 2 so that the resin of the body 2 migrates into the woven fabric element of theerosion-resistant layer 4.
