Abstract
We present results of studying mechanical properties of four groups of metallic and nonmetallic composite materials in a temperature range of 300–4.2 K. Types of glass-reinforced and carbon-reinforced plastics with the best low-temperature strength and elastic characteristics have been specified. A deterioration of the strength characteristics of boron-fiber-reinforced aluminum alloy after temperature cycling in the temperature range 20–443 K has been detected. It has been shown that superconducting composites with ultra-fine filaments, fabricated by hydrostatic extrusion without intermediate annealings, possess optimal combination of mechanical and electrical characteristics.
