  • Process for the production of a multidirectional textile preform and piece of composite material incorporating said preform
    Publication number: 20040244859
    Abstract: A process for the production of a textile preform from interlaced filaments or sections of filaments, using a support (16) of a shape appropriate to the preform, on which are applied superposed layers of filaments or sections of filaments crossed in at least two directions, the layers being interconnected by filaments or sections of filaments which pass through them, and the filaments or sections being stretched or held on the support (16) by pins (18). The method further includes the step of reimplantation of the pins (18) by offsetting them, so as to avoid the concentration of defects inherent in the use of pins.
