Abstract

Due to its remarkable mechanical qualities, composites are now widely used in unconventional industries, particularly aircraft. During assembly, drilling CFRP composite elements is a common activity, and choosing the right process parameters and geometry is essential to prevent drilling-related damage like delamination. This has led to the creation of a mathematical model that forecasts the required thrust force at which delamination occurs, taking into account the thermo-mechanical stresses and mixed failure mode in the separation area for unidirectional composites.The procedure is divided into three steps: i) an Experimental drilling thrust force study; (ii) an analysis of how scheduling the feed rate and fibre orientation can reduce delamination. It was discovered that only changing the feed rate is insufficient to prevent delamination. This research will look at drilling CFRP composites’ performance optimization strategies. The study concentrates on crucial performance traits such as thrust, torque, average hole roughness, and delamination factor (both at the entry and exit). The objective is to identify the ideal machining settings that can successfully balance these aspects.
