The invention relates to a method for the manufacture of a recyclable product
material in order to achieve a predetermined strength within a predetermined
strain rate interval. The product material comprises at least one matrix
material and at least one fibre material. The matrix and fibre materials are
chosen so that the values of their moduli of elasticity (Eij), moduli in shear
(Gij) and the Poisson's ratios (ij) assume a discontinuous distribution of the
said matrix and fibre material quantities within different volume elements of
the product material. It is further intended that a display curve defining a
continuous distribution of a fibre size of the product material should exhibit
symmetry in different volume elements of the product material.
Cette invention concerne un procédé de fabrication d'un produit fait d'un matériau recyclable et possédant une résistance prédéterminée dans un intervalle de taux de déformation prédéterminé. Ce produit se compose d'au moins un matériau matriciel et d'au moins un matériau fibreux. Les matériaux matriciel et fibreux sont choisis de manière à ce que les valeurs de leurs modules d'élasticité (E¿ij?), de cisaillement (G¿ij?) et de leurs coefficients de Poisson (?¿ij?) permettent d'obtenir une répartition discontinue des quantités desdits matériaux matriciel et fibreux pour des éléments de volumes différents faits dudit matériau. D'après cette invention, il est également souhaitable qu'une courbe graphique représentant une répartition continue de la taille des fibres du matériau composant le produit, présente une symétrie pour des éléments de volumes différents faits dudit matériau.
