Fibre orientation is the arrangement of the reinforcing fibres in a composite part, which determines its directional strength, stiffness and shrinkage.
In chopped-fibre materials such as C-SMC (carbon sheet moulding compound) or BMC (bulk moulding compound) the fibres flow with the resin during moulding, so their orientation depends on the shape of the mould and the placement of the charge. It is predicted by simulation, for example in Moldex3D with the Fiber module.
