The invention provides a fibre-reinforced polymer composite comprising fibres derived from mammalian hair and/or feathers, wherein the fibres have been prepared by means of a process comprising the steps of: (a) subjecting mammalian hair and/or feathers to an oxidation treatment in which the hair and/or feathers (is) are contacted with a solution, which comprises a bleaching agent; (b) separating the oxidised hair and/or feathers from the solution; and (c) drying the separated hair and/or feathers. The invention further provides processes to prepare said composite, a process to prepare said fibres, and shaped polymer products comprising said composite.
L'invention concerne un composite polymère renforcé par des fibres, comprenant des fibres dérivés de poils et/ou de plumes de mammifères, caractérisé en ce que les fibres sont préparées suivant un processus comprenant les étapes suivantes : (a) soumettre les poils et/ou les plumes des mammifères à un traitement d'oxydation au cours duquel les poils et/ou les plumes sont mis en contact avec une solution comprenant un agent de blanchiment ; (b) séparer de la solution les poils et/ou les plumes oxydés ; et (c) sécher les poils et/ou les plumes séparés. L'invention concerne en outre des procédés de préparation dudit composite, un procédé de préparation des fibres, ainsi que les produits polymères mis en forme comprenant ledit composite.
