Some observations in grinding unidirectional carbon fibre-reinforced plastics
This paper investigates the grinding performance of epoxy matrix composites reinforced by unidirectional carbon fibres, using an alumina grinding wheel. Emphasis was placed on understanding the effect of fibre orientations and grinding depths on the grinding force and surface integrity, and on understanding the grinding mechanisms, with a comparison to orthogonal cutting. It was found that grea...
متن کاملImage Characterization of Carbon Fibre Reinforced Composites
A new methodology to detect fibres orientation in composite materials, using image processing tools is introduced. Several examples with manufacturing defects are studied using RIMAPS technique and the Variogram method. The characterization is made from digitized images of the samples. Combined use of RIMAPS and Variogram analyses identified the orientation of fibres and determined the values o...
متن کاملMachining of Fibre Reinforced Plastic Composite Materials
Fibre reinforced plastic composite materials are difficult to machine because of the anisotropy and inhomogeneity characterizing their microstructure and the abrasiveness of their reinforcement components. During machining, very rapid cutting tool wear development is experienced, and surface integrity damage is often produced in the machined parts. An accurate selection of the proper tool and m...
متن کاملAssessment of the Exit Defects in Carbon Fibre-Reinforced Plastic Plates Caused by Drilling
This paper investigates the formation of the exit defects in carbon fibre-reinforced plates and characterizes their features in terms of drilling conditions. It was found that spalling and fuzzing are the major mechanisms of exit defects. The spalling, consisting of a main region and a secondary region, is caused by chisel and cutting edge actions, in which the former plays a key role. The fuzz...
متن کاملModelling the effective elasto-plastic properties of unidirectional composites reinforced by fibre bundles under transverse tension and shear loading
The effect of fibre bundling on the effective transverse properties of unidirectional fibre composites has been investigated by way of finite element method and micromechanics models of fibre bundles. Based on the micromechanical model of single-fibre composites, plane strain models for composites reinforced by fibre bundles are presented. The effective elasto-plastic stress /strain behaviour w...
