Face turning trials were carried out on glass fibre reinforced plastics (GFRP), carbon fibre reinforced plastics (CFRP) and kevlar fibre reinforced plastics (KFRP) cylindrical tubes to study their machined surfaces for possible application as friction surfaces. The surface roughness obtained and the observed morphology of the machined surfaces of fibre reinfoced plastics (FRP) composites are compared and are reported in this paper. The mechanisms of material removal and tool wear are also discussed and illustrated with scanning electron micrographs. The cutting forces encountered during machining of composites were also measured. © 1988.

Machinability characteristics of fibre reinforced plastics composites

Journal of Mechanical Working Technology

Drilling studies were conducted on glass/epoxy composite laminates having two different lay-ups [(0/90)4s and (0/ ± 45/90)2s]. Normal drills (2 flute with cone angle of 118°) made of high-speed steel (HSS), TiN-coated HSS, and TiC-coated HSS were used. Drilling parameters were optimized in terms of least thrust and torque. Parameters studied were thrust, torque, tool wear, form deviation, acoustic emission peak, and root mean square (RMS) of acoustic energy. It was observed that coated HSS drills perform little better than uncoated HSS for small number of holes, while their performance is inferior to uncoated HSS for larger number of holes. This is mainly due to peeling or chipping of the coating from base material (HSS). Also, the performance of TiN-coated HSS drill was observed to be better than TiC-coated HSS.
