With strong expertise in cutting-edge industrial fields, the CSI's teams offer to design with you your products in composite materials and shape them in our workshops.
Our multi-material expertise, both metallic and composite, will allow us to support you towards a product that combines performance, resistance and lifespan.
Thanks to composite materials, you can :
- Lighten your components currently made of metal,
- Guarantee a very high mechanical resistance of your components,
- Have parts that resist corrosion,
- Obtain long-life components in an irradiated environment,
- Ensure the resistance of your components subjected to powerfull electromagnetic forces.
Our expertise is mainly focused on structural parts. Whether lightened or reinforced, large, and/or for harsh environment, our structures meet the highest performance requirements.
Large composite structure with internal polyurethane parts.
Large composite rings subjected to very high loads (~500 MPa in annular tension) and to a temperature of 4K (-270°C).
Composite door meeting naval requirements (acoustics, lightness, operating reliability, etc.)
1 composite worshop 100% integrated
From design to full-scale parts qualification : everything happens on our industrial site in La Seyne-sur-mer with our teams. We are a a vertically integrated supplier, able to develop special processes and to industrialize them.
Our industrial tool is 100% adapted to large scale and the achievement of out-standing performance. Our composite workshop is part of this logic.
- XXL shaping : dry machining, winding of pultruded material, filament winding, infusion, pre-impregnation (autoclave)…
- Large dimension metrology
- Laboratory dedicaded to material choices and characterizations
- Heat treaments (XXL ovens, autoclave)
- Scale 1 test benches to validate the expected performances. Custom developed.
