Drilling of Polymer-Matrix Composites

Abstract

Nowadays, composite materials are used within primary load carrying aircraft structures. Recent examples are Boeing 787 and Airbus A350XWB where the composite weight content has increased to 50–60 %. However, joining of a composite part on a structure often requires manufacturing holes in order to place bolts or rivets. To obtain these holes, different processes can be implemented such as drilling or moulding. Drilling process concerns a conventional machining procedure where the composite materials are machined to produce hole. Nonetheless, it implies destruction of fibre continuity, large stress concentration and delamination at the hole entry and the hole exit. Such result of damages can cause significant reduction in both tensile and compressive strength of composite structure.
