Machinability of fibre-reinforced plastics / edited by J. Paulo Davim.

Print version record.

Presents Polymer-based fibre reinforced composite materials and addresses the characteristics like low density and coefficient of thermal expansion, specific strength with better fatigue resistance and modulus. The authors attend to the application problematic given that the structural components integration requires machining even after they precisely fabricated in most of the high production rate industries like aerospace and automobiles.
