A method for producing a fibre reinforced three-dimensional product comprises depositing of long fibers in a mould consisting of a frame in which a carrier net for the fibers is suspended. The individual layers of a formed plane laminate are positioned in such a manner that only a first end is secured at a frame side. Said first ends are secured at different frame sides. In this manner it is possible, in a pressing procedure giving the product is three-dimensional shape, to obtain a virtually even distribution of the fibres, even in areas which are subjected to the longest move away from the plane original laminate. In this manner sound well-defined properties are obtained in the three-dimensional product formed.

[ I claim:] [1.] A method for producing a fibre reinforced three-dimensional product of a plastic material by using a mould in which the product is formed, said mould having at least one edge area, said mould comprising a pressing frame and a lower mould, wherein a plane laminate composed of crossing fibre arrangements is formed containing long fibres which are uniformly oriented and which are mixed with a plastic matrix, wherein the plane laminate is deposited loosely on a carrier net with first ends of the long fibres projecting out from the laminate to form a deposited plane laminate, said carrier net being suspended in a carrier frame, said carrier frame with said plane laminate deposited on said carrier net being positioned between said pressing frame and said lower mould, wherein the deposited plane laminate is heated to form a heated plane laminate; wherein only said first ends of the long fibres are secured by securing members in the at least one edge area of the mould, the securing members being activated while second ends of the long fibres are free in the mould and lie proximate a diametrically opposite side of the mould, wherein the carrier net is released from the frame when said first ends of said long fibres are secured by the securing members, wherein the heated plane laminate is pressed into a desired three-dimensional shape to form the fibre-reinforced three-dimensional product under continued securing of the long fibres at said first ends, wherein said long fibres retain their orientation during and after said pressing step, and wherein the fibre-reinforcecd three-dimensional product is released and removed from the mould.
