Abstract
A method for the production by resin injection moulding of fibre reinforced articles from fibrous material bonded in a curable matrix material which articles comprise two or more spokes (2, 3, 4) extending from a hub portion (1), each spoke (2, 3, 4) being in the form of a loop is characterized in that the fibrous material is arranged such that at least as many rovings (13, 14, 15 or 22, 23, 24) of the fibrous material as there are spokes (2, 3, 4) extend in continuous paths from the hub portion (1) around each of the spokes, each of the rovings being overlaid for at least part of its length by each of the other rovings. The method is suitable for the production of intricately shaped articles which are to be highly stressed for example by being subjected to high rotational speeds.

A method for the production by resin injection moulding of articles from fibrous material bonded in a curable matrix material which articles comprise two or more spokes extending from a hub portion, each spoke being in the form of a loop, comprising:
- arranging the fibrous material in a mold so that at least as many rovings of the fibrous material as there are spokes extend in continuous paths from the hub portion around each of the spokes, each of the rovings being overlaid for at least part of its length by each of the other rovings and injection molding curable material about said fibrous material and curing said curable material.
