Title: The Innovative Contributions of Jean-Marie Parenteau
Introduction
Jean-Marie Parenteau is a notable inventor based in Bordeaux, France. He has made significant contributions to the field of composite materials and engineering, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is a method of producing a nozzle or a divergent nozzle element made of a composite. This invention involves obtaining a fiber preform by conforming panels of fiber texture on a former that reproduces the desired shape of the nozzle. The panels are bonded together at their edges, and a consolidated fiber reinforcement is formed by shaping the impregnated fiber preform. This process ensures that the final product has a fiber volume percentage of at least 35% and a thickness of less than 5 mm over a significant portion of its axial dimension. The densification of the fiber reinforcement is further enhanced by chemical vapor infiltration after pyrolyzing the resin, resulting in a part that closely resembles the intended shape and wall thickness of the nozzle.
Another significant patent by Parenteau is for a high-speed composite turbine wheel. This innovative wheel comprises a central portion with blades at its periphery, made from a single piece of composite material. The fibrous reinforcement is constructed from a helical fabric with both radially and circumferentially oriented fibers. The density of these fibers varies along the radius of the wheel, accommodating the radial and circumferential stresses experienced during operation. The materials used in the construction of the wheel are selected for their high mechanical resistance and resistance to high temperatures and chemical attacks.
