New Composite Material Surpasses Aluminum Alloys in Strength

Researchers at Peter the Great St. Petersburg Polytechnic University in Russia have developed a groundbreaking composite material that outperforms many aluminum alloys in strength. Published in the International Journal of Adhesion and Adhesives, their findings highlight a composite crafted from alternating layers of glass or carbon fiber-reinforced plastic and metal, primarily aluminum. This structure not only offers lower density but also superior impact and fatigue strengths compared to traditional materials.

Central to the innovation is the enhanced adhesion between layers, achieved through the use of fullerene carbon black, an inexpensive nanomaterial derived from graphite burned in an inert gas atmosphere. According to Ilya Kobykhno, head of the Polymer Composites Laboratory, this breakthrough improves both the strength and impact resilience of the material, marking a significant advancement in composite technologies. The potential applications for this new material span across various sectors, including transport and general engineering, with particular implications for the aircraft and aerospace industries. Kobykhno also noted the scalability of the production process, which leverages a by-product of fullerene production, suggesting that this development could soon see widespread industrial implementation.
