Fiber Application Head with Retractable Flap
21 Sep 23
The present invention relates to a fibre application head for the production of composite material parts, comprising a compaction roller (3), guiding means (4), a retractable flap (6) which can be displaced between an active position in which the said flap is able to come by its distal end (63) against the fibre in order to bring the said fibre in abutment against with the roller, and a retracted position in which said flap is spaced apart from the roller, and a heating system (5) able to emit thermal radiation (51) towards of the nip zone between the roller and the application surface.

Method for Producing a Composite Material Part by Oriented Needling of a Preform
17 Jun 20
A method for producing a composite material part comprising—a step of producing a preform formed of unidirectional continuous fibers oriented in at least one fiber orientation,—a step of applying non-woven filaments to the preform, and—a step of needling the filaments by means of a needling device comprising a plurality of needles, each needle being provided with a notch extending along a notch axis perpendicular to the main longitudinal axis of the needle, or several notches each extending along a notch axis perpendicular to the main longitudinal axis of the needle, the notch axes being parallel to each other, the needles and the preform being arranged so that the notch axes form a non-zero angle with the fiber orientation.
