摘要： A composite component such as a blade or vane of a gas turbine engine comprises a body 2 and an erosion-resistant layer 4. The body 2 comprises a fibre reinforcement 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 a thermoplastics material such as PEEK, and may be thicker at the leading edge 6 of the component than at pressure and suction surfaces 8, 10. The component may be manufactured 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 of the body 2 so that the resin of the body 2 migrates into the woven fabric element of the erosion-resistant layer 4.
摘要翻译：诸如燃气涡轮发动机的叶片或叶片的复合部件包括主体2和耐腐蚀层4.主体2包括树脂基体中的纤维增强件，并且抗侵蚀层4包括3-D 机织织物也是树脂浸渍的。机织织物元件由诸如PEEK的热塑性材料制成，并且在部件的前缘6处可以比在压力和吸力表面8,10处更厚。该部件可以在铺设过程中制造，其中将抗侵蚀层4的无纺布元件放置在具有树脂浸渍的主体2的纤维增强体的模具中，使得主体2的树脂迁移到耐腐蚀层4的织造织物元件中。
