Title: The Innovative Contributions of Alain Lefumeux
Introduction
Alain Lefumeux is a notable inventor based in Orsay, France. He has made significant contributions to the field of pyrotechnics, holding a total of 8 patents. His work focuses on developing advanced materials and processes that enhance the performance and safety of pyrotechnic products.
Latest Patents
One of Lefumeux's latest patents is for non-detonatable pyrotechnic materials designed for microsystems. This invention involves novel materials that are less than 500 µm thick or weigh less than 15 mg. These materials can sustain combustion after localized initiation with electrical power ranging from 150 mW to 800 mW for a duration of 20 ms to 600 ms. The composition includes 25% to 80% by weight of an energy-releasing binder, along with ammonium perchlorate and potentially nitramine. These materials are intended for use as miniature gas generators, propulsion units, or heat generators.
Another significant patent by Lefumeux is a continuous process for the solvent-free manufacture of heat-curable composite pyrotechnic products. This process allows for the continuous industrial production of small crosslinked composite pyrotechnic charges without the constraints of 'pot life'. The method involves mixing a heat-curable liquid binder with a thickening filler to create a viscous premix that remains unreactive at ambient temperature.
