る。However, in such a conventional composite material using a thermosetting resin, the toughness of the resin is low and the resin is brittle. There is a problem of contamination, and further, there is a problem that the crushing of the matrix resin causes many scratches on the cutting surface, which deteriorates the appearance. For this reason, a great deal of man-hours are spent on the polishing of the face surface, but the finish is still inadequate, and the amount of cutting and polishing increases, so the surface fiber layer of the composite material disappears and the designability is improved. The current situation is that
