Abstract: A process for continuously forming reinforced articles (24) which includes producing a reinforcing material (13) having a plurality of superimposed layers (1-6), stitching together said layers (1-6), wetting said reinforcing material (13) with a matrix material (7, 8 or 19), forming the wetted reinforcing material and curing or consolidating the matrix material. Each layer (1-6) of the reinforcing material (13) includes a plurality of unidirectional non-woven yarns or threads (10) laid side-by-side, the yarns or threads (10) in at least some of the different layers (1-6) extending in different directions. Forming of the wetted reinforcing material may be effected by moulding, pultrusion or by wrapping wetted reinforcing material around a mandrel or former (25).
