Abstract

The invention relates to a method for producing a shell-like moulded article, the walls of which are formed in a positive and/or negative mould from a fibre-reinforced supporting layer of a liquid synthetic resin with hardener and at least one top coat of a modified, liquid synthetic resin, arranged on one side of the supporting layer and bonded integrally to the same. In order to develop this method in such a way that less work is involved in producing the top layer and the styrene emission is considerably reduced, as well as allowing the possibility of applying the top or gel coat subsequently to the already produced supporting layer, it is proposed that a deformable space is formed between the mould and the supporting layer, that a predetermined quantity of liquid synthetic resin required for the top coat is filled into the space and that this space is subsequently deformed by pressure and/or vacuum and the top coat thereby formed. <IMAGE>
