A mat (10) useful for reinforcing composite materials is made up of at least first (16) and second (18) sets of fibers, the first set of fibers (16) laid as a ply in spaced apart parallel relationship in the direction of construction and the second set (18) laid as a ply in spaced apart parallel relationship perpendicular to the direction of construction. These fibers define interstices (22), into which a continuous filament (20) is knitted to provide stability. The filament (20) has a core portion (34) and a sheath portion (36), the sheath portion (36) having a lower melting point than the core portion (34). The sheath portion (36) is thermally fusible to form a plurality of closed loops in which the respective sets of fibers are entrapped. The fibers (16, 18) are glass or glass rovings and the filament (20) is a polyester, the core portion being a high-viscosity poly(ethylene terephthalate) and the sheath portion being a low-viscosity poly(ethylene terephthalate).

La présente invention concerne un mat (10) utilisé pour des matériaux composites d'armature, constitué d'au moins un premier (16) et un second (18) ensemble de fibres. Le premier ensemble de fibres (16) est posé sous forme de couche espacée et parallèle dans le sens du tissage et un second ensemble de fibres (18) est posé sous forme de couche espacée et parallèle perpendiculairement au sens de tissage. Ces fibres forment des interstices (22) dans lesquels un filament continu (20) est tissé pour fournir une stabilité à l'ensemble. Ce filament (20) comporte une partie noyau (34) et une partie gaine (36). La partie gaine, qui présente un point de fusion inférieur à celui de la partie noyau (34), est fondue à la chaleur pour former une pluralité de boucles fermées dans lesquelles sont piégés les ensembles de fibres respectifs. Ces fibres (16, 18) sont des fibres de verre ou des stratifils de fibres de verres et le filament (20) est un polyester. La partie noyau est constituée de poly(éthylène téréphthalate) à viscosité élevée et la partie gaine est constituée d'un poly(éthylène téréphthalate) à faible viscosité.
