Title
(EN) METHODS OF MANUFACTURING VOIDFREE RESIN IMPREGNATED WEBS
(FR) PROCEDES PERMETTANT DE PRODUIRE DES TISSUS IMPREGNES DE RESINE EXEMPTS D'INTERSTICES
Abstract
(EN)
A method for manufacturing a cured resin impregnated substrate (106) comprising placing a substrate into an impregnation zone (38) including a solvent containing curable resin to produce a resin impregnated substrate wherein the number of voids in the cured resin impregnated substrate are reduced by processing the substrate in at least one processing step that reduces the number of voids in the cured resin impregnated substrate product.
(FR)
L'invention concerne un procédé permettant de produire un substrat (106) imprégné de résine durcie. Ce procédé consiste à placer un substrat dans une zone (38) d'imprégnation renfermant un solvant qui contient une résine durcissable afin de produire un substrat imprégné de résine. Ce procédé permet de réduire le nombre d'interstices dans le substrat imprégné de résine durcie grâce à au moins une étape de traitement du substrat au cours de laquelle le nombre d'interstices dans le substrat imprégné de résine est réduit.
