Title: Jacques Dazord: Innovator in Carbon Fiber Coating Technologies
Introduction
Jacques Dazord is a notable inventor based in Villeurbanne, France. He has made significant contributions to the field of materials science, particularly in the coating of carbon fibers. With a total of 2 patents, Dazord's work focuses on innovative processes that enhance the properties of carbon filaments.
Latest Patents
Dazord's latest patents include a process for coating carbon fibers with a carbide. This process involves continuously coating a strand of carbon filaments using a refractory carbide through a reactive technique. The method requires the strand to travel under mechanical tension within a hermetic enclosure. During this process, a carbon-free gas mixture, consisting of hydrogen and a volatile compound capable of forming a refractory carbide, is introduced into the enclosure. The reaction mixture is then heated under controlled conditions, allowing for the formation of a carbide deposit on the filaments through a chemical reaction. This self-regulated reaction produces a thin, homogeneous passivation coating on each filament.
Another patent by Dazord also focuses on the continuous coating of carbon filaments with a carbide using reactive CVD deposition. Similar to the previous process, this method involves the strand traveling under mechanical tension within a hermetic enclosure. A gas mixture of hydrogen and a volatile compound is introduced, and the reaction mixture is heated to facilitate the formation of the carbide deposit. The self-regulation of the reaction is achieved through the diffusion of carbon through the already formed carbide layer.
