INSTALLATION FOR PRODUCING NEEDLE FIBROUS PREFORMS FOR THE MANUFACTURE OF PARTS MADE OF COMPOSITE MATERIAL.

摘要

The installation comprises a support tool (10) whose shape corresponds to that of the preform to be produced and on which can be draped in superimposed layers of layers of a two-dimensional fibrous texture, a needling head (30) comprising a group of needles, a device for driving the needles in reciprocating translational movement parallel to themselves, and a support plate, provided with perforations for the passage of the needles, and capable of being applied with pressure against a draped stratum on the support tool, an arm (25) carrying the needling head and having several degrees of freedom, and a device (28) for automatic movement control of the arm to move the needling head, within the radius of action of the arm, following trajectories and with predetermined orientations.
