The present invention is directed to a reinforcing non--woven base fabric that is formed through processes in which a group of warp yarns, composed of a plurality of reinforcing fiber yarns that are aligned in a fixed direction with fixed intervals or closely, is superposed on a group of fusion--bonding multifilament yarns made of composite fibers that are aligned in a direction perpendicular to the fixed direction so that the two groups are bonded to each other through fusion--bonding, and a manufacturing method and a manufacturing machine for such a reinforcing non-woven base fabric.
L'invention concerne un tissu de base non tissé pour renforcement préparé par mise en parallèle d'une pluralité de fils de fibres de renforcement dans un sens, avec un espace constant ou dense, afin de produire un groupe de fils de chaîne; par superposition, sur ledit groupe de fils de chaîne d'un groupe, de fils multifilament thermofusibles composés d'une fibre composite parallèle dans un sens presque perpendiculaire au sens du groupe de fils de chaîne; et par collage des deux groupes de fils ensemble par thermofusion. L'invention concerne également un appareil permettant de produire le tissu de base.
