Abstract:
1. 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.
