Evaluation of heat resistance of carbon fiber reinforced plastics based on organosilicon compounds

The paper presents composite materials based on elastomeric matrices in combination with phenol-formaldehyde resin, reinforced with carbon fiber fabric. Technology of obtaining composites is described. Polymer binder has been modified by introducing inorganic additives (SiC, ZrB₂, glass microspheres). Experimental data of thermogravimetric analysis of the obtained carbon plastics are presented. Comparative tensile strength tests of composite materials have been carried out before and after plasma treatment. Materials described in the paper are intended for use in high-temperature heat shielding. (paper)
