碳纤维增强双马来酰亚胺树脂基复合材料体系冲击后压缩强度研究

探讨了树脂基体、碳纤维增强体以及树脂基体 纤维的界面等对双马来酰亚胺 (简称双马 )树脂基复合材料冲击后压缩强度 (CAI)值的影响 ,指出降低树脂基体的交联密度和产生微观两相结构是提高碳纤维 /双马复合材料CAI值的两个典型方法。合适的树脂含量有利于保持复合材料体系较高的CAI值 ,采用高强高韧性的碳纤维可明显提高复合材料体系的CAI值。为获得较高的CAI值 ,保持合适的树脂基体 纤维界面性能也是必要的

Investigation on compression strength after impact of carbon fiber reinforced bismaleimide resin matrix composites

Compression Strength After Impact (CAI) is the most important parameter of characterizing the toughness of carbon fiber reinforced resin matrix composites Influence of bismaleimide (BMI)resin matrix, carbon fiber and fiber matrix interface on the CAI of BMI resin matrix composites was discussed in this paper Decreasing cross linking density and producing two phase micro structure in BMI resin are two typical ways to enhance the CAI of carbon fiber/BMI composites A suitable resin content is necessary to obtain high CAI of a composite system Carbon fibers with excellent toughness and mechanical properties contribute significantly to increase the CAI of composites Proper fiber resin matrix bond is also necessary to achieve high CAI value
