MIMOSA - Sistema Poli

Multimaterial airframes based on 3D joints between AM metals and carbon-fiber composites

Description

The MIMOSA Project’s goal is to create multi-material joint structures using innovative concepts that can take advantage of digital and hybrid processes to generate superior technological and financial outcomes than the existing traditional joints. Additionally, MIMOSA will pioneer the incorporation of recycling from the product and business ideation stage forward, paving the way for the circularity of materials and manufacturing. Using novel technology and a competitive technique for multi-material joints between AlSi10Mg alloy for additive manufacturing (AM) and composites (CFRP, carbon fiber-reinforced polymers), these goals and related needs will be met. The project suggests a new concept design for the joint, the regeneration of after-service materials, a reduction in weight (-51%), a reduction in lead time (-65%), and a reduction in the process’ total environmental footprint.

Result to be enhanced

Innovative technology and competitive process for multi material joints between AlSi 10 Mg alloy for additive manufacturing (and composites carbon fiber reinforced polymers).

-new concept design of the joint.

-after service materials regeneration (50% of metals and 90% of CFRP).

-weight (-51%) and lead time (-65%) reduction.

-overall process environmental footprint reduction.

Why is it important?

MIMOSA stands out as a key innovation initiative in aerospace engineering. It addresses major challenges in sustainability, performance, and industrial scalability through:

Structural joints without rivets or adhesives, improving efficiency and reliability

Integration of metal additive manufacturing and composite technologies

Recyclability of aircraft structures at end of service life

Regeneration of secondary raw materials, supporting material circularity

Development of certification guidelines for next-generation joint technologies
