Abstract:
PCT No. PCT/EP95/00273 Sec. 371 Date Jul. 25, 1996 Sec. 102(e) Date Jul. 25, 1996 PCT Filed Jan. 25, 1995 PCT Pub. No. WO95/20475 PCT Pub. Date Aug. 3, 1995The invention relates to a method of making a composite laminate comprising the steps of providing unidirectionally oriented parallel fibres (UD filaments) (3) with a resin matrix to form a composite UD layer and laminating a plurality of UD layers to form a UD crossply laminate (18). In the method of the invention, the UD filaments are impregnated with a melt of a resin which in the uncured form solidifies below a certain temperature (Tm). Thereupon the UD filaments-containing resin is cooled to a temperature below Tm to produce the composite UD layer. The produced composite UD layer is irreversibly cured before or after lamination. Notably latent curing resins are suitable. The impregnation is preferably conducted by coating a process belt (8) with solid resin (6), laying the UD filaments onto the resin, and heating the resin so as to form the resin melt. The heating of the resin is preferably conducted by means of IR irradiation (11).
