碳纤维复合材料螺栓连接性能综述

Summary for the connection performance of carbon fiber composite bolt

碳纤维复合材料具有众多优良的性能,目前在民用及航空航天领域已被广泛应用,但是碳纤维复合材料的结构连接强度问题一直是制约其发展的重要因素。综述了碳纤维复合材料螺栓连接方法,分别讨论了碳纤维增强复合材料螺栓连接的强度理论、强度预测和强度影响因素(干涉配合、预紧力、螺栓钉头形式及铺层顺序)对连接强度的影响规律。最后总结了碳纤维复合材料螺栓连接研究的发展趋势。

Carbon fiber composite has many excellent properties. It has been widely used in the field of civil and aerospace, but the structural connection strength of earban fiber reinforced cmposites has been an important factor restricting its development. This summarizes the method of carbon fiber composite bolt connection. The strong theory, strength prediction and influence factors of the bolt connection of carbon fiber composite materials （ interference fit, pretightening force, the form of the screw head and the sequence of the stacking sequence） are discussed respectively. Finally, the development trend of carbon fiber composite bolt connections is summarized.
