1. A process for fabricating a multidirectional fibrous reinforcement designed to be a porous preform for producing a part made of a composite material, said process comprising the steps of:

  • depositing at least one reinforcing thread in at least two successive layers on a support surface;

    providing a binder in association with said reinforcing thread so as to adhere said reinforcing thread to said support surface wherein said binder also provides a bond between said successive layers; and

    pressing said reinforcing thread against the support surface during said depositing step in a manner that exerts a pressure substantially perpendicular to said support surface at the point where the thread is deposited.
