Title (EN) CERAMIC POLYMER COMPOSITE TOOL
(FR) OUTIL COMPOSITE EN POLYMERE CERAMIQUE
Abstract:
(EN) An improved metal working tool or die (30) having an outer surface formed from synthetic resin material that is filled with a hardener. The outer surface is formed of a material that consists of a synthetic resin mixed with tabular alumina and a surface treating agent such as gamma-Methacryloxypropyltrimethoxysilane. The tool or die (30) is formed over a pattern (10) by applying the outer hard surface layer (14) to the pattern (10) and then a second or intermediate layer (8) of synthetic resin that is filled with calcium silicate. A third layer (16) of material that includes a reinforcing fiber such as fiber glass is applied over the intermediate layer (8).
(FR) Outil ou matrice (30) pour le travail des métaux amélioré(e) présentant une surface extérieure formée de matériau à base de résine synthétique, remplie de durcisseur. La surface extérieure est formée d'un matériau constitué de résine synthétique mélangée avec de l'alumine tabulaire et d'un agent de traitement de surface tel que du gamma-méthacryloxypropyltriméthoxysilane. L'outil ou matrice (30) est formé(e) sur un gabarit (10) par l'application de la couche de surface dure extérieure (14) sur le gabarit (10) puis d'une deuxième couche ou couche intermédiaire (8) de résine synthétique remplie de silicate de calcium. Une troisième couche (16) de matériau comprenant une fibre de renforcement telle que de la fibre de verre est appliquée sur la couche intermédiaire (8).
