A Fractal Model of Reinforcement of Carbon Polymer–Nanotube Composites with Ultralow Concentrations of Nanofiller

The structural aspects of determining the degree of reinforcement (increase in elasticity modulus) of carbon polymer–nanotube composites with ultralow concentrations of nanofiller are considered. It is shown that the specified parameter is controlled by two factors, the structure of the nanocomposite and the type of reinforcing component. The introduction of a nanofiller in the polymer matrix modifies its structure due to the formation of interfacial regions. Hence, the efficiency of nanofiller as the reinforcing element is determined by its ability to generate interfacial regions.
