Mechanical properties of new functional composite materials based on polymeric binders

Abstract

Composite materials which include components (binding and fillers) that provide technological and operational characteristics were investigated. As a fillers AlN, Al(OH)3, SiO2, CaSi03 powders are used. Binder – dimethylsiloxane rubber SKTN A + PMS silicone oil in 4:1 proportion. Studied composite materials are designed for dielectric coatings materials creation, which have a high thermal conductivity and do not support combustion (through the use of fillers with flame retardant properties). The results of experimental studies of the mechanical characteristics of composite materials based on siloxane binder and fillers in the form of fine powders AlN, Al(OH)3, SiO2, CaSi03 are presented. The values of strength, coefficient of elasticity, relative elongation in tensile tests, modulus of elasticity in compression tests, Shore hardness are measured.
