ABSTRACT:
A method of molding a fibre reinforced resinous material comprising providing fibrous reinforcement in an initially uncured resin matrix, initiating a cycle which will result in the curing of the matrix and which includes an initial cure phase and a post cure phase, and selecting any one or more of the resin system, cure phases or initial cure temperature so that the sum of the fractional thickness change during the initial cure phase and the fractional thickness change during the post cure phase being equal to or differing by a predetermined amount from the fractional dimensional change in the plane of the fibre reinforcement at the desired end-use temperature at which greatest dimensional accuracy is required.
