Title: Innovations of Louis G Heraud
Introduction
Louis G Heraud is a notable inventor based in Bordeaux, France. He has made significant contributions to the field of thermostructural composite materials, holding a total of six patents. His work focuses on the development of advanced materials that can withstand extreme conditions.
Latest Patents
One of his latest patents is a process for the manufacture of a thermostructural composite material. This innovative material is produced by forming a fibrous preform made from refractory fibers coated with a sizing agent. The preform is then densified by a refractory matrix, particularly ceramic, while a carbon interphase is provided between the fibers and the matrix. The fibrous preform is made from refractory fibers coated with a sizing agent that leaves behind a carbon residue upon thermal decomposition. The carbon interphase is produced by the thermal degradation of the sizing agent, which occurs after the preform is made. The sizing agent is selected from phenolic, acrylic, and cellulose resins, specifically carboxymethylcellulose.
Another significant patent involves a cooled refractory structure and its manufacturing process. This structure consists of a composite material that has a reinforcement texture and a matrix. The composition of the matrix varies continuously in the thickness direction of the structure, transitioning from an essentially refractory material at the front face, which is exposed to very high temperatures, to a material that is primarily heat conductive. Cooling fluid circulation conduits can be arranged within the structure where the matrix is essentially heat conductive.
Career Highlights
Throughout his career, Louis G Heraud has worked with prominent companies such as Societe Europeenne de Propulsion and Jacques Cotteret. His experience in these organizations has contributed to his expertise in the field of composite materials.
