In this article, the machinability of unidirectional carbon fiber reinforced by epoxy composites when subjected to orthogonal cutting was investigated. And the authors found that the subsurface damage and its mechanisms of a machined component are greatly influenced by fibre orientation.Abstract:
This paper aims to understand the machinability of epoxy composites reinforced by unidirectional carbon fibres when subjected to orthogonal cutting. It was found that the subsurface damage and its mechanisms of a machined component are greatly influenced by fibre orientation. The material’s bouncing back is a characteristic phenomenon associated with the cutting of a fibre-reinforced composite. Three distinct deformation zones appear, i.e., chipping, pressing and bouncing when the fibre orientation isread more
