摘要: 本文简要地介绍了复合材料风扇叶片较传统的金属材料风扇叶片的优越性,回顾了复合材料风扇叶片的发展概况,对复合材料凤扇叶片的设计、制造、加工、检验方法进行了介绍,并着重分析了复合材料风扇叶片抗外物;中击能力差的主要弱点,以及人们为改善此弱点所做的工作,主要包括使用混杂纤维复合材料和超混杂复合材料等新的结构设计形式来提高其抗外物冲击的能力。

Abstract: This paper shows a potential advantage of composite fan blades over the traditional metal fan blades. The history of the development of composite fan blades is reviewed. The design fabrication, molding inspection, finishing operation and nondesetructive evaluation methods are introduced. Emphasis is given to the analysis of resistance to foreign abject damage of composite fan blades.The fan blade design Concepts of leading edge shield composite, internal metal spar composite, solid hybrid composite, spar shell composite and superhybrid composite as an internal spar configuration, designated Ti Core,and a leading-edge spar configuration,-designated TiCom are evaluated briefly, on the basis of reviews, we consider that superhybrid composite fan blade is most possible of being introduced into the fan rotor assembly of commercial turbofan engine.
