CARBON CONSTRUCTION PURPOSE BASED ON AROMATIC POLYAMIDE AND METAL-CONTAINING CARBON FIBER

Abstract

The main thermophysical and physico-mechanical characteristics of the aromatic polyamide phenylon C-2, reinforced
with a metal-containing carbon fiber, have been investigated. It is shown that the reinforcement of the polyamide binder with
chromium-containing carbon fiber in an amount of 17 wt. % significantly reduces the specific heat and the temperature
coefficient of linear expansion, and also improves its physical and mechanical properties. It was found that the developed
carbon fiber reinforced plastic has an average of 20-60% and 6-12 % lower, respectively, in comparison with the binder, the
temperature coefficient of linear expansion and specific heat. Reinforcement of a polyamide binder with a carbon fiber filler
increases its yield point and modulus of elasticity in compression by 20 and 124 MPa, respectively.
