Lavoisier Composites

LAVOISIER COMPOSITES is a start-up specialized in the development of eco-sourced composite materials and parts.

Production hazards lead to the removal of materials or parts because they go beyond the limits of an established specification or an expected period of use.
This process is at the origin of a major wastage. While their residual properties would be considered of very good level for a number of applications, these materials excluded from the aeronautical processing industry unfortunately end up in an incinerator or landfilled.
The famous 18th century chemist Antoine LAVOISIER‘s law "Nothing is lost, nothing is created, everything is transformed" is at the foundation of Lavoisier Composites and Carbonium®.
Implemented following a process that has been the subject of 3 patents, Carbonium® brings its aerospace grade structural properties and a totally unique aesthetic to the parts obtained.

Company Lavoisier Composites



Carbonium is a new generation of carbon fiber composite material entierly sourced from the Aerospace supply-chain.

An aircraft is a product of long life cycle, nevertheless at the end of life, composite materials contained will have to be recycled. For such a purpose, industrial units have been established across the world to recover mainly by Pyrolysis Carbon Fiber from cured composites waste. For today, the concern is more on massive and recurring volumes of post-production residues generated every day. Bearing in mind that about 2/3 of these volumes are still reactive thermosets, the use of existing recycling technics to recover carbon fiber only is a nonsense. Instead, at Lavoisier Composites we believe that we can reuse these high added value residues to recover carbon fiber AND resin. That’s why we have developed CARBONIUM®. Specifically, to manufacture the different versions of the Carbonium® range: 1. We supply by-products of carbon / epoxy prepregs originally intended for structural parts of commercial civil aircraft. 2. Although discarded from the aeronautical manufacturing process, these batches of materials are traced and controlled to enter our manufacturing process. 3. From these materials, our process allows us to obtain products: a. in bulk form also called "BMC" (for Bulk Molding Compound), b. in the form of a roll mat also called "SMC" (for Sheet Molding Compound). These products are specially designed for compression molding in order to obtain parts of variable geometrical complexity. Depending on the material configurations and the molding process, it is possible to obtain very good mechanical properties. The particularity of our product is to obtain complex geometries while keeping fiber lengths up to 50mm. With no less than 2/3 carbon fiber mass content and the use of structural epoxy resins 180 °C class, we get a high-performance product whose density (1.55) is almost half of that of the aluminum. In addition to being moldable, our product can be drilled and machined according to technical constraints. This machinability allowed us to exploit an interesting aesthetic rendering in the Original version or in the Gold version in collaboration with the Swiss watchmaking company Ulysse Nardin. The first two luxury watch models (Freak X and Skeleton X) presented at the last SIHH show (International Salon of Haute Horlogerie) in Geneva in January 2019 are already a commercial success. Since our products are sourced from by-products of the French and European aerospace industry, their environmental impact is much lower. The LCA (Life Cycle Assessment) conducted in connection with a consultant enabled us to evaluate the overall impact improvement from -40 to -50% on the various criteria. Compared with an equivalent compression molding product sourced from virgin raw materials, the climate change criterion corresponds to a saving of 13kg of CO2 equivalent per Kg of product.
