Innovations and Benefits

Aeronautics and space industries require light materials with high performance in terms of thermo-mechanical properties, hardness and erosion/corrosion resistance. Ceramic materials are often the only ones that can achieve the performance required for these extreme environments, in association or replacement materials traditionally used.
CVI/CVD technology are the preferred technique for the production of high performance materials. It is a high flexible process, thanks to its ability to change the nature of the deposited materials and furthermore allows the simultaneously production of components with different geometries and near net shape.

Use

Functional components and devices for engines, thermal protection systems, structural components, thermal barriers.
CVI/CVD technology applications:
• ceramic composites production;
• ceramic coating development;
• porous component functionalization.

Applications and ongoing Activities

CVI/CVD pilot sized plant is set up in Faenza laboratories TEMAF.
The results of the research activities are supported by collaborations with companies in the sector, both as contracts and as joint participation in local and European projects, and by registered patents.
