摘　　要：以国产高强中模CCF800H碳纤维为基础增强材料,以CCM40J及CCM55J高模量碳纤维为混杂增强体、AC631高温双马来酰亚胺树脂为基体,制备不同纤维比例的面内混杂预浸料。结合热压罐成型工艺,制备并表征五组不同碳纤维混杂比例的复合材料的力学性能。根据测试结果,分析了不同混杂复合材料体系的力学性能变化,得到CCF800H/CCM40J(5∶5),CCF800H/CCM40J(4∶6),CCF800H/CCM55J(5∶5)三组典型混杂配比的复合材料体系,均表现出较好的力学性能。这可为飞机复合材料结构件的研制提供参考的基础材料性能数据。With domestic high-strength medium modulus CCF800H carbon fiber as the basic reinforcement material,CCM40J and CCM55J high modulus carbon fibers as the hybrid reinforcements,and AC631 high-temperature bismaleimide resin as the matrix,the in-plane hybrid prepregs with different fiber ratios were prepared.Combined with the autoclave molding process,the mechanical properties of five groups of composite materials with different carbon fiber hybrid ratios were prepared and characterized.According to the test results,the changes in the mechanical properties of different hybrid composite systems were analyzed,and three groups of typical hybrid ratio composite systems,CCF800H/CCM40J(5∶5),CCF800H/CCM40J(4∶6),and CCF800H/CCM55J(5∶5),were obtained,all of which showed good mechanical properties.This can provide reference basic material performance data for developing aircraft composite structural parts.
