Title (EN) FIBER-REINFORCED COMPOSITE MATERIALS AND SHAPED ARTICLES
(FR) MATERIAU COMPOSITE RENFORCE AVEC DES FIBRES ET ARTICLES FORMES
Abstract: front page image
(EN)In composite materials comprising an organic and/or inorganic matrix, e.g. a cement matrix, reinforcing bodies such as fibers are surrounded by a contact domain comprising a material which is different in composition from as well the matrix as the fiber. The contact domain comprises a material such as a polymer which provides slidability of the fiber in the matrix so as to provide a controlled bond strength between the reinforcing body and the matrix, and/or the contact domain comprises ultra fine silica particles. Ultra fine silica particles provide a chemical protection of glass fibers. The matrix is particularly a cement/ultra fine silica matrix where the cement particles are densely packed and the ultra fine silica is homogeneously arranged and preferably substantially densely packed in the voids between the cement particles. Such matrix is prepared from a slurry of a very low water content by means of a concrete superplasticizer. Protection of silicate fibers against deterioration is obtained by incorporation of a catalyst poison.
(FR)Dans des materiaux composites comprenant une matrice organique et/ou inorganique, p. ex. une matrice de ciment, des corps de renforcement tels que des fibres sont entoures par un domaine de contact consistant en un materiau dont la composition est differente de celle de la matrice et de celle de la fibre. Le domaine de contact comprend un materiau tel qu"un polymere qui donne une capacite de glissement a la fibre dans la matrice de maniere a obtenir une resistance de liaison controlee entre le corps de renforcement et la matrice, et/ou le domaine de contact comprend des particules de silice ultrafine. Les particules de silice ultrafine assurent une protection chimique des fibres de verre. La matrice est, particulierement, une matrice de ciment/silice ultrafine ou les particules de ciment sont entassees de maniere dense et la silice ultrafine est disposee de maniere homogene et est de preference entassee sensiblement de maniere dense dans les vides entre les particules de ciment. Une telle matrice est preparee a partir d"une boue de tres faible teneur en eau au moyen d"un superplastifiant de beton. La protection des fibres de silicate contre la deterioration est obtenue en incorporant un poison de catalyseur.
