A Review on Drilling of Natural and Synthetic Fiber Reinforced Polymer Composites: 1992 - 2021

ABSTRACT

The drilling of natural and synthetic fiber-reinforced polymer and their hybrid composites are a crucial machining process, which becomes essential in helping the assembly of parts. The quality of drilled hole is very crucial for recent applications owing to its dimension tolerance. This paper presents a study on drilling characteristics of natural and synthetic fiber-reinforced polymer composites and their hybrids. Assessment of delamination, thrust force, torque, influence of drill bit for drilled hole quality and effect of chemical treatment of natural fiber are discussed. Influence of composite specimen thickness and burr formation for synthetic fiber are also reported. Influence of speed, feed, feed rate, drill bit type, drill diameter, drill bit angle, fiber orientation and their optimum conditions for drilling are also reported for both natural and synthetic fiber. Results showed that, minimum delamination can be achieved by high cutting speed and low feed rate. Increasing the number of parameters and level of optimization will improve the accuracy of the results.
