Title (EN) PROCESS FOR MANUFACTURING A COMPOSITE FIBRE/RESIN MATERIAL AND MATERIAL SO OBTAINED
(FR) PROCEDE DE FABRICATION DE MATERIAU COMPOSITE FIBRES/RESINE ET MATERIAU OBTENU
Abstract:
(EN) According to the process, before the material is moulded a sheet of calandared fibrous material impregnated with melamine and prepolymerized is applied to the surface of the mould instead of a mould release agent, layers of fibres and other materials and resin are placed in contact with said sheet, and the whole assembly is polymerized in conditions appropriate to the resins used and under a pressure of at least 1 bar.
(FR) Suivant ce procédé, préalablement au moulage du matériau, on applique sur la surface du moule au lieu d'un agent de démoulage une feuille d'une matière fibreuse calandrée imprégnée de mélamine et pré-polymérisée, on dispose les couches de fibres et autres et de résine en contact avec ladite feuille et on polymérise l'ensemble dans les conditions appropriées pour les résines utilisées et sous une pression d'au moins 1 bar.
