FIELD: casting.
SUBSTANCE: group of inventions relates to a modular mould for creating auxetic behaviour or wavy configurations for panels using continuous fibres with a possibility of embedding alternative materials. The modular mould comprises a layer (10) of a fibre-reinforced material. The layer (10) therein is configured for forming hollow cells (3) containing a wavy trapezoidal cross-section. Said modular mould therein comprises at least three moulding strips for forming each hollow cell (3). One moulding strip (4) therein has a trapezoidal transverse shape and two moulding strips (5) have a triangular transverse shape. The trapezoidal moulding strip (4) therein is configured to be located between the two triangular moulding strips (5). The three moulding strips (4, 5) are made so that the cross-section thereof forms the shape of a trapezoidal cross-section of a hollow cell (3) when said strips are connected.
EFFECT: increase in the efficiency of manufacturing a panel, increase in the efficiency of absorbing the energy of potential impacts, and reduction in the weight of the panel.
