Surface treatment of carbon fiber reinforcement to increase adhesion with butadiene elastomer

This study presents the results of the study of increasing the adhesive interaction of butadiene elastomer with the reinforcing fabric based on carbon fiber. Increased adhesion of elastomer with carbon fiber was achieved by surface treatment of reinforcing fabric with dissolved rubber mixture in toluene and Chemosil adhesive mixture. Examination of high-modulus materials for delamination of elastomer from carbon fiber showed an increase in adhesion strength. When a reinforcing fabric is treated with Chemosil adhesive mixture, the destruction occurs over the elastomer, the bond strength to the carbon fiber exceeds the cohesive strength of the elastomer. Increase of adhesion between reinforcing filler and butadiene matrix leads to change of elastic and strength properties of obtained high-modulus materials: increase of tensile strength and hardness, decrease of relative elongation and abrasion resistance. The method of electron microscopy has established that the surface treatment of carbon fabric leads to the formation of a dense contact with the elastomeric matrix. Thermomechanical analysis shows that these materials can be operated at negative temperatures.
