Title: Innovations by Michel Jehan: A Pioneer in Composite Tubular Products
Introduction
Michel Jehan, an innovative inventor based in La Flamengrie, France, has made significant contributions to the field of composite manufacturing. With a total of two patents to his name, Jehan's work focuses on enhancing processes that introduce additives into molten metal baths. His expertise and inventive spirit have propelled him to great heights in the industry.
Latest Patents
Jehan's latest patents revolve around the manufacture of a composite tubular product. Specifically, these inventions outline a method for introducing a reactive powder into a molten metal bath. In this process, a reactive powder is enclosed within a tubular sleeve made of a metal compatible with the bath. Remarkably, the cross-section of the sleeve is reduced after filling, which compacts the powder while maintaining its porosity. The filled sleeve can be efficiently formed by profiling a metal strip into a cup-shaped cross-section, followed by metering the powder into this profile. The edges of the strip are then closed together to encase the powder, after which they are shaped to hook together and crimped securely.
