Title: Innovations of Patrice Dourthe
Introduction
Patrice Dourthe is a notable inventor based in Rion des Landes, France. He has made significant contributions to the field of composite materials, particularly through his innovative patents. With a total of five patents to his name, Dourthe's work focuses on the development of maleic resins and bis-maleimide resins that can be set by ionization.
Latest Patents
Dourthe's latest patents include compositions of maleic resins that can be set by ionization. This invention relates to compositions that comprise a maleic resin and a reactive diluent, which includes compounds such as dipentaerythritol pentacrylate and hydroxyethyl methacrylate. The total quantity of reactive diluent ranges from 10 to 70 parts by weight per 100 parts by weight of maleic resin. These compositions allow for the production of composite materials with fibrous reinforcement that can be set by ionization without the need for additional post heat treatment. Another significant patent involves a process for the hardening of a bis-maleimide resin. This process includes adding a reactive diluent to a basic resin prior to its use, which is then subjected to ionizing radiation. The total quantity of the diluent is carefully measured to ensure the maleimide functions of the basic resin are consumed during the radiation action.
