ABSTRACT:
A method for manufacturing an article of fibre reinforced resin material includes the preparation of a reinforcement preform which includes one or more roves of staple fibres with sufficiently low twist to enable the fibres to slide relative to each other and thereby the rove to elongate when subjected to tension. The reinforcement preform is shaped by deforming the preform into the desired three dimensional shape of the article being manufactured. The shaping can be carried out before, after or simultaneously with impregnation with matrix material. The matrix material may be thermoplastic material incorporated in or with the preform.
