摘要: 随着复合材料在飞机上的应用正在由次承力结构到主承力结构的扩展,长桁、梁等加强框也逐步采用复合材料。作为民机发动机吊挂的主承力件,研究了A形加强框采用复合材料RTM成型工艺可行性,对模具设计、材料铺层设计、注胶模拟、注胶口选择以及注胶参数优化等方面进行了研究,并完成了复杂结构件的机加工,最终研制出满足工艺要求的结构件。

Abstract: As the application of composites has been broaden from the secondary structures to the primary structures of aircrafts, the stiffeners such as stringers and frames are made of composites rather than metals. To develop the primary structure of the pylon of civil aircrafts, a stiffener with A shape is experimentally studied using the RTM processing. The mold design, the layup design, the choice of the inlet and outlet, and the injection parameters optimization are studied, based on which the A stiffener is machined successfully.

Key words: RTM, stiffener, injection simulation, mold design
