Abstract
A process for manufacturing a curved part of composite material, during which the layers of fibers of composite materials that will compose the part are held taut at least during the bending step, and displacement of the layers with relation to each other is controlled, is disclosed. A device capable of implementing this type of processs is also disclosed.
Claims10
A manufacturing process for a curved part of composite material, comprising:
- laying out a group of composite material fiber layers flat onto a support layer;
- placing the support layer together with the layers of composite material fibers between two plates, respectively an upper plate and a lower plate, with the lower plate adjacent to a preform presenting a curvature radius corresponding to an internal curvature radius desired for the part being manufactured;
- placing the support layer under tension;
- heating the support layer along with the layers of composite material fibers;
- bending the support layer and the layers of composite material fibers;
- measuring a sliding of the layers of composite material fibers with relation to each other;
- and
- stopping the bending of the layers when the composite material fibers have slid sufficiently to attain a desired angle.

A device for manufacturing a curved part of composite material, comprising:
- a lower plate;
- an upper plate;
- a preform with a radius of curvature, the preform extending beyond an edge of the lower plate;
- a support layer intended to extend at least partially over the upper and lower plates and to receive successive layers of composite fiber material used for manufacturing the curved piece;
- a traction system capable of maintaining the support layer under tension;
- and
- a system for measuring movement of the layers of composite fiber material with relation to the at least one of support layer or the lower plate.
