Abstract
Assessment of Process Parameters Influencing Delamination Factor on the Drilling of CFRC Composite Material with TiN Coated Carbide Tool
Highlights
Drilling is the process of production of holes by removing the material with the help of a tool called drill bit
The Carbon-Carbon composite materials, which are nothing but Carbon Fibre Reinforced Carbon Composites (CFRC), are the logical materials for the production of emerging structures like space shuttles, missiles, launching vehicles, advanced defence items, aircraft brakes, racing car brakes, prosthetic devices and other bio materials
Even literature is available on the drilling of Carbon Fibre Reinforced Polymer (CFRP) composites but not on the drilling of CFRC composites
Summary
Drilling is the process of production of holes by removing the material with the help of a tool called drill bit. It is a frequently used machining process and commonly used final operation in assembly of the advanced structures. The ubiquitous twist drill bits, used in metalworking work well in composite material, but they tend to chip that out at the Entry and Exit of the hole[1]. Drilling is a complicated operation and it becomes more complicated if the material is a composite one. Delamination of fibres is the major damage, generally occurring in drilling of composite materials. The quality of product, generally, depends upon the process parameters.
