Date Feb. 3, 1994The invention relates to a method of manufacturing a composite laminate, preferably a cross-ply laminate, in which process unidirectionally oriented (UD) fibres (3) are provided with matrix material (7) and, together with a pre-formed non-flowing UD composite or cross-ply laminate, passed through a laminating zone (13) in layers of at least two different orientational directions. More particularly, the invention relates to the manufacture of composite material which is pre-eminently suited to be used as a supporting substrate for printed wire boards. The method according to the invention is directed in particular to the utilisation of a double belt press, both for making the preformed non-flowing UD composite and for the manufacture of the final laminate. The invention also comprises printed wire board (PWBs) and multilayer PWBs.</p> |
