Abstract
A method of forming or reforming a composite material comprises relatively rotating a pair of members (2,3) while urging them together under pressure so as to mix or remix together the materials (1) making up the composite. The urging direction is substantially parallel with the axis of relative rotation. The composite is then extruded (7).
