1. Method of manufacturing by moulding in a single pass, a moulded composite panel comprising a base formed from discontinuous glass or rock fibres, impregnated with a polymerized binder and a visible covering sheet, characterised in that an initial component is prepared by impregnation by soaking with a non-polymerized binder so as to obtain an initial component with a binder ratio of approximately 10 to 30% by weight of the total dry extract, at least one layer of fibres bonded with a polymerized binder, obtained by spraying on the fibres, a solution of the non-polymerized binder during the formation of the layer of fibres, followed by the polymerization of the binder, whereby the ratio of the polymerized binder is approximately 2.5% by weight of the layer of bonded fibres, that the initial component is placed on the visible covering sheet and that all the components are pressed accompanied by heating so as to obtain the composite panel by polymerization of the binder and bonding of the components between themselves.
