Review on Machinability of Fiber Reinforced Polymers: A Drilling Approach

Performance of conventional materials in diverse engineering application is not satisfactory due to the development in products design and engineering materials. In this case, fiber reinforced Polymers (FRPs) have attracted the material engineers with their unique properties and their expansion in various applications. The superior characteristics of the FRPs emphasized their advancement in machining performance. So it becomes more significant to analyze their machinability for further improvement in their machining characteristics and applications. The intention of this paper is to review the machining response of FRPs especially on drilling. Concerning FRPs drilling operation the main aspects were focused on glass, natural and carbon fiber reinforced polymers. Drilling damages such as delamination of plies, thrust force, and surface quality in response to various parameter influences were also discussed in detail.
