In addition to a high stability but also a light weight is desirable, so that a preferred range of values between 0.30 g / cm 3 and 0.65 g / cm 3 , in particular between 0.35 g / cm 3 and 0.45 g / cm 3 . Wood fiber mats have significant advantages over other natural fiber mats for the invention. These include the consistent quality of the wood fibers due to the biological relationships described above compared to the grades of natural fibers from 1 year or less growth, which fluctuate greatly from crop to harvest year.

Abstract

L'invention concerne un matériau composite en fibres, en particulier pour la construction de skis ou de planches à neige. Ce matériau composite en fibres est constitué d'une part la plus élevée possible de fibres de bois, interconnectées les unes avec les autres sous forme de mat avec ou sans orientation préférée des fibres, et dans lesquels des matières plastiques dures ou élastomères sont incorporées. Grâce à la densité élevée et surtout régulière, pouvant être définie, des fibres de bois des mats, on obtient un matériau homogène ayant des propriétés mécaniques régulières, mais qui peuvent aussi être modifiées de manière ciblée à différents emplacements du noyau.
