A process for the manufacture of a plastics article which comprises bringing at least two plastics into contact with one another and shaping them and bonding them to one another at the contact surface, wherein at least one of the two plastics comprises components which react with one another during the shaping, at least in the region of the contact surface, and the other of the two plastics in the liquid state during the shaping, at least in the region of the contact surface, and wherein at least one of the reactive components has a pronounced tendency to diffuse into the other plastic. The diffusing component may be a monomer or low-molecular weight constituent of one plastic and a solvent for the other plastic. The composite article may be formed by injection or extrusion moulding. One plastic may be a thermosetting polyester and the other plastic may be polystyrene or polymethyl methacrylate. The polyester may be reinforced with glass fibres.
