为研究金属补片式复合材料修补结构的强度、疲劳性能及剩余强度性能,分析对比了单排及双排铆钉连接的金属补片式复合材料修补结构的破坏模式、静力破坏载荷、疲劳寿命及剩余强度,结果表明,双排铆钉连接的修补结构的强度、疲劳性能及剩余强度性能均优于单排铆钉连接的修补结构,研究结果可为铆钉连接的金属补片式复合材料修补结构强度及疲劳设计工作提供参考。
In order to study the strength, fatigue performance and residual strength performance of metal patch composite repair structure, the failure mode, static failure load and fatigue life of metal patch composite repair structure with single row and double rows of rivets were analyzed and compared. The results show that the strength, fatigue performance and residual strength performance of the double-row rivet-connected repair structure are better than those of the single row rivet connection. The research results may be that the structure of the rivet-connected metal patch composite structure is repaired And fatigue design work to provide reference.
