A reinforcing fabric (101) or (30) contains a layer of reinforcing fibers (12), (10a) and (10b), and a polymeric coating (15) holds the fibers (12), (10a) and (10b) while the fibers are under mechanical strain to increase the thickness of the layer by at least about 50%. The warp yarns (12) are held under tension in a tenter frame (105) while applying the polymeric coating (15). A matrix material is reinforced by the reinforcing fabric (101) or (30). The matrix material is, a soil reinforcement material, a pipe forming material, a road surfacing material, a cement board material, a gypsum board material, a roofing membrane material, a roofing shingle material, a textile material, or a surgical cast material.

L'invention concerne un tissu de renforcement (101) ou (30) qui contient une couche de fibres de renforcement (12), (10a) et (10b), et un revêtement polymère (15) qui retient les fibres (12), (10a) et (10b) lorsque celles-ci sont sous contrainte mécanique afin d'accroître l'épaisseur de la couche d'au moins environ 50 %. Les fils de chaîne (12) sont maintenus sous tension dans une rame (105) pendant l'application du revêtement polymère (15). Un matériau de matrice est renforcé par le tissu de renforcement (101) ou (30). Ce matériau matriciel est un matériau de renforcement pour le sol, un matériau de formation de conduite, un matériau de revêtement des routes, un matériau de plaque de ciment, un matériau de plaque de plâtre, un matériau de revêtement d'étanchéité de toiture, un matériau de bardeau de toiture, un matériau textile, ou un matériau moulé chirurgical.
