A method for producing fiber-reinforced materials based on natural renewable raw materials such as polymers made of epoxy solids which are ring-opened with carboxylic acids, with suitable comonomers as a matrix material and natural fibers, whereby said materials have a high tensile strength when the proportion of fibers amounts to 25-45 wt. %.
L'invention concerne un procédé pour produire des matériaux composites renforcés par des fibres, à base de matières premières renouvelables naturelles, par exemple à base de polymères constitués de matières solides époxydées, ayant subi une ouverture de cycle avec des acides carboxyliques, comportant des comonomères appropriés en tant que matériau matriciel, et de fibres naturelles. Ce procédé permet d'obtenir des matériaux présentant une grande résistance à la traction, lorsque la proportion de fibres est comprise entre 25 et 45 % en poids.
