The use of a variety of composites due to their superior properties, which include low weight, high strength, and high corrosion resistance, which are generally many applications in the aerospace, automotive, and marine structures have increased significantly. Fiberglass reinforced composites have several industrial applications due to their suitable mechanical and physical properties. Drilling is one of the common methods for connecting structures made of reinforced materials with fibers. Composite structures usually result from the joining of members to transmit and tolerate incoming forces. One of the methods of connecting the members, due to the ease of maintenance and repair, is the mechanical connection through screws or rivets, which inevitably must create holes in these members. Composites as materials that are difficult to machining, drilling these materials can lead to delamination and, in some cases, degradation. In this paper, the effects of drilling on mechanical joints in composite structures and solutions to prevent damage to them due to drilling are investigated.

各种复合材料的使用由于其优越的性能，包括重量轻、强度高和耐腐蚀性高，通常在航空航天、汽车和海洋结构中的许多应用中显着增加。玻璃纤维增​​强复合材料由于其合适的机械和物理性能而具有多种工业应用。钻孔是将增强材料制成的结构与纤维连接起来的常用方法之一。复合结构通常是通过连接成员来传递和承受传入力的结果。由于易于维护和修理，连接构件的方法之一是通过螺钉或铆钉的机械连接，这不可避免地必须在这些构件上开孔。复合材料作为难以加工的材料，钻探这些材料会导致分层，在某些情况下还会导致降解。本文研究了钻孔对复合结构中机械接头的影响以及防止钻孔损坏机械接头的解决方案。
