Title
(EN) SEMI -FINISHED COMPOSITE MATERIALS CONTAINING NATURAL FIBERS AND PRODUCTION THEREOF
(FR) MATÉRIAUX COMPOSITES SEMI-FINIS CONTENANT DES FIBRES NATURELLES ET LEUR PRODUCTION
Abstract
(EN)
The invention comprises unidirectional thermoplastic prepreg structures containing reciprocal surfaces/faces, wherein one surface includes uni-directionally oriented natural fibers and the other surface includes randomly oriented natural fibersand the production of these structures in one step.
(FR)
L'invention comprend des structures unidirectionnelles de préimprégné thermoplastique contenant des surfaces/faces réciproques, une surface comprenant des fibres naturelles orientées de manière unidirectionnelle et l'autre surface comprenant du sable naturel orienté de manière aléatoire, la production de ces structures en une seule étape.
