Abstract: A composite panel consists of a natural stone layer (1) and a reinforcing layer (13) that has a fibre layer (2) embedded in synthetic resin, and at least one layer (3) of synthetic resin. The fibre layer (2) serves as tensile reinforcement and the layer (3) of synthetic resin serves as compression reinforcement for the natural stone layer (1), so that the composite panel can absorb both positive and negative bending moments. The synthetic resin layer (3) is reinforced, for example, with a fine-mesh glass fibre textile (6) that faces towards the tensile reinforcing fibre layer (2) and an adjacent glass fibre mat (8). In order to produce the composite panels, natural stone panels that have been cut to a greater thickness are coated on both sides with the reinforcing layer (13). A plurality of coated natural stone panels are then arranged so as to be equally spaced on their center planes, and then simultaneously divided.
