Disclosed is a method for producing a fiber composite/fiber-reinforced plastic part from rovings (R) by means of a mold (1). Said method comprises the following steps: - rovings (R) formed from dry fibers are applied to the mold surface (3) by stretching the rovings (R) by means of an application device (13), tensile force being applied between deflection devices in the predefined orientation; - binder material is applied to the stretched rovings (R); - the arrangement of fiber strands and binder mate-rial is consolidated by applying temperature and pressure such that a preform for the part to be produced is formed; - the preform is detached from the deflection devices and is removed from the mold (1); and - once the preform has been detached from the de-flection devices, an injection process or infusion process is carried out in order to form the part. Also disclosed are a mold (1) and a device for carrying out said method.
Procédé de fabrication d'un élément en matériau/plastique renforcé par des fibres à partir de mèches (R) au moyen d'un moule (1), ce procédé comportant les opérations suivantes: appliquer des mèches (R) formées de fibres sèches sur la surface du moule (3) par tension des mèches (R) au moyen d'un dispositif d'application (13), une tension étant créée entre des dispositifs de renvoi dans une orientation donnée; appliquer un agent liant sur les mèches (R) tendues; consolider la disposition de faisceaux de fibres et d'agent liant par application d'une température et d'une pression pour obtenir une préforme de l'élément à fabriquer; dissocier la préforme des dispositifs de renvoi et sortir la préforme du moule (1); après dissociation de la préforme des dispositifs de renvoi, effectuer une injection ou une infusion pour former l'élément. L'invention porte également sur un moule (1) et sur un dispositif destinés à réaliser ce procédé.
