Evaluation of CFRP Composite Laminates by Drilling Using Finite Element Approach

Abstract

Numerical modelling of material behavior & defect formation during machining was made possible by the years. Rapid expansion of the usage of carbon fiber composite materials, which are extensively employed in a variety of civilian industries, including aviation, aerospace, defense, automotive, electronic information, and high-speed machinery. Drilling is a vital final machining process for components made of composite laminates. Determining static structural, dynamic, or vibrational, and explicit dynamics is a crucial challenge in drilling CFRP. In this work, the drilling behavior of CFRP composite laminate with five layers is analyzed. Drilling behavior is examined using the finite element method while taking into account the precise geometrical considerations as well as the static, dynamic, and explicit factors involved in the operation in order to find the initial modes and corresponding natural frequency using Ansys workbench 19.2 and Catia V5 software used to modelling required 3d Geometry.
