Scientists from Peter the Great St. Petersburg Polytechnic University (SPbPU) have created a new composite material. It is stronger than many aluminum alloys.
The basis for the creation of the new development was fiber-metal laminates. This popular class of composites consists of alternating layers of metal (for example, aluminum), glass and carbon fiber. It is this combination that makes the new material unique in its fatigue, strength and density properties compared to aluminum.
The properties of the composite are enhanced by the fact that when a crack is impacted or increased, the released energy is dissipated between the polymer and the metal. But such a reaction is possible only in the case of adhesion (high strength of compounds) - this is exactly what the SPbPU scientists worked on.
We have improved the adhesion of the surfaces of different layers of the material through the use of an inexpensive and easy-to-use nanomaterial - fullerene soot.
The plans are to use the new material in industry, in particular, to use it in mechanical engineering and the construction of various kinds of structures.
Fullerene soot nanoparticles are a cheap and affordable nanomaterial obtained by burning graphite in an inert gas and also a by-product of fullerene production, so the development can be easily scaled up for industrial implementation.
According to the expert, such studies make it possible to develop new methods for joining metal and composite parts, as well as improve the properties of fiber-metal laminates.
Earlier www1.ru reported that in Russia developed a new material for optoelectronic devices in the near-IR range on silicon.
