Composite materials are advanced materials created by combining two or more components with different properties to form a new material that outperforms the individual constituents. Typically, they consist of a polymeric, metallic, or ceramic matrix鈥攚hich determines the material's shape鈥攁nd a reinforcement, often made of fibers (carbon, glass, or ceramic-based), which provides mechanical strength, stiffness, and dimensional stability. Thanks to these characteristics, composite materials are increasingly used in sectors where high performance, weight reduction, and long-term durability are critical.
In this context, Matrix First emerges as an innovative method developed by the Hybrid Materials Laboratory at the MEMTi Institute, under the leadership of Prof. Alberto Ortona. By combining computational design with additive manufacturing, this approach enables the creation of complex matrices with engineered internal cavities, which are subsequently filled with high-performance fiber tows. The result is an optimized structure, specifically designed and manufactured to meet defined functional requirements and significantly enhance the material's performance under operating conditions.
