摘要
基于高强、高韧、高模和压拉平衡为特征的第三代先进复合材料的需求,综述了连续纤维增强树脂复合材料纵向压缩强度预测模型的发展历程。基于纤维微屈曲、纤维扭结带、联合预测模型及渐进损伤失效模型,分别讨论了连续纤维增强树脂复合材料压缩失效机制,并在联合预测模型基础上,探究了碳纤维(直径、模量、体积分数、初始偏角)、树脂基体(弹性模量、剪切模量)及纤维/树脂界面三要素对连续纤维增强树脂复合材料纵向压缩强度和压缩失效形式的影响。
Based on the demand of the third generation of advanced composites characterized by high strength,high toughness,high modulus and the balance of compressive and tensile strength,the development history of prediction model of continuous fiber reinforced polymer composite compressive strength was reviewed.The compressive failure mechanisms of continuous fiber reinforced polymer composites were discussed according to fiber microbuckling model,fiber kink-band model,combined model and progressive damage failure model.On the basis of the combined prediction model,the effects of carbon fiber(monofilament diameter,elastic modulus,volume fraction,initial deflection angle),polymer matrix(elastic modulus and shear modulus)and fiber/polymer interface on compressive strength and failure mode of continuous fiber reinforced polymer composite were investigated.
