The invention relates to a stack (1) for moulding parts in a plastic material, comprising an assembly of layers, each layer (2) comprising a plastic material (MP) and at least one reinforcing element (ER) having at least one main slenderness direction (DP), characterised in that the reinforcing elements (ER) of one layer have at least one main slenderness direction which is different from that of the reinforcing elements of at least one other layer, said different main slenderness direction being selected so as to define a direction of voluntary anisotropy in the stack (1). |
