About us

H-PreC is a family business founded in July 2015 by Cécile CRASSOUS and her brother Arnaud, PhD in materials physics and a researcher at the Ecole Polytechnique Fédérale in Lausanne. The company is funded by Daniel Le Gal, founder of Gemalto, and by BPI France. 

The company was born from an observation: The use of composite materials increases in the industry. There are plenty of opportunities, but to seize them, companies have to face a major challenge: optimize processes and production rates in order to make composite materials more competitive.


Our first production unit is based in a high-tech building of 1000m² in Carros near Nice Airport. Two million euros were invested to adapt the actual production line to mass production: automatic fabric cutting, large capacity 5-axis CNC machine, machine and tooling for high-speed production...

Our company develops and manufactures thermosetting composite from its two exclusive industrial processes that make the high-quality composite accessible from prototype to mass production. 

Today we own two exclusive patented fabrication processes: the H-PreC One-Step® and the H-PreC BloK®.


Our processes and products are destined to manufacturers who want to take advantage of composite materials or optimize their current composite solutions.
