Abstract
In this study, flow-induced fibre reorientation in carbon fibre SMCs after compression moulding has been investigated experimentally using an image-based fibre orientation analysis technique. The effect of processing parameters, i.e., charge coverage and initial preferential alignment on fibre reorientation and mechanical performance has been studied. Greater fibre alignment was observed in the direction of greater flow distance, hence plaques with smaller charge coverage exhibited higher flow-induced alignment. Furthermore, panels made from highly aligned longer fibre tows maintained more of the preferential alignment due to the greater resistance of longer fibre tows to flow induced alignment. The measured anisotropy in the tensile properties of coupons taken from two orthogonal directions supported the observations from fibre orientation analysis.
