ABSTRACT:
A method of producing laminar structures, preferably consisting of fibreglass-reinforced polyester, which are free of air-pockets and pores, by spraying layers of the plastics and reinforcement fibres at a partial vacuum. The method may be carried out by an industrial robot. An airtight surface layer may be sprayed onto the laminate, whereby any pores or air-pockets collapse when the laminate is exposed to air at atmospheric pressure.
