Title: The Innovative Contributions of Joel Bretagne
Introduction
Joel Bretagne is a notable inventor based in Saint-Nazaire, France. He has made significant contributions to the field of composite materials, holding a total of 2 patents. His work focuses on innovative manufacturing processes that enhance the efficiency and effectiveness of composite material applications.
Latest Patents
One of his latest patents is a press for forming an article of composite material. This press features a fixed lower platen and an upper platen that is movable vertically by means of an actuator. A former, which corresponds to the article to be obtained, is placed on the lower platen via a thermal insulation member. The former includes channels for the circulation of a heat exchange fluid. The material to be formed is placed on the former, while the upper platen carries an assembly with a resilient membrane. The periphery of this membrane is sandwiched between a lower frame and a cover connected to a source of fluid under pressure. The sealing between the membrane and the lid is ensured by the clamping pressure between these two parts, which results partly from the force exerted on the moving platen and partly from the pressure of the fluid.
Another significant patent by Bretagne is a method of manufacturing a protective sheath made of laminated material based on fibers impregnated with resin. This method utilizes a cylindrical draping mandrel, showcasing his innovative approach to composite material manufacturing.
