Surface Characteristic and its Mechanism of the Drilled CFRP

Abstract:

Article Preview

The drilled surface characteristic of epoxy resin reinforced by multi-directional carbon fibers is investigated based on experiments. With the emphasis on the effect of fiber direction, the mechanism of inhomogeneous surface topography is discussed. Besides, the mechanism of drilling-induced delamination and splitting defects are analyzed, and the drill condition and drilling parameters are also considered. It is indicated that the varied fiber direction is the main cause resulting in the inhomogeneous topography; delamination is easy to occur between two adjacent laminas which have different fiber directions, and it is more serious near the exit of drilled hole.
