中文摘要:随着先进复合材料在民用飞机上的大量应用,对复合材料结构件的修理技术研究显得尤为重要。胶接挖补修理是一种成熟的层压板永久性修理方法,其中胶接斜面挖补修理工艺简便,在民用飞机中应用广泛,可用于修理损伤范围小于15%零件表面积的分层、脱粘、多余孔等缺陷。工程上一般采用静强度计算方法对修理后零件的强度性能进行评估。在对复合材料层压板零件进行胶接斜面挖补修理及强度计算分析后,结果表明修理及其静强度评估方法的工程应用可行。
英文摘要:With the extensive application of advanced composite materials on civil aircraft, it is particularly important to study the repair technology of composite structures. The bonding scarf patch repair of laminate plate is a kind of mature repair method. Among them,the bonding inclined surface scarf patch repair method is simple and widely used in civil aircraft. It can be used to repair defects such as delamination, debonding and superfluous holes of parts with damage range less than 15%. Static strength calculation method is generally used in engineering to evaluate the strength performance of repaired parts. The repair and strength calculation of composite laminate part have been carried out and the results show that the repair and static strength evaluation method is feasible in engineering application.
