Research of the Influence of Carbon Microfiber on the Properties of Elastomer Fire-Protective Materials

Resumo

The influence of carbon microfiber on the physicomechanical, thermophysical, and fireproof characteristics of elastomeric compositions based on ethylene propylene diene rubber is considered. Microfibrous filler contributes to the manifestation of the effect of “micro-reinforcement,” which leads to an increase in the heatprotective properties of the material due to the increase in the strength of coke. The correction of microfibers with a phosphorus-boron-containing oligomer enhances the carbonization of the material, which leads to an increase in the warming-up time of the unheated sample surface by 8–10% and a decrease in the linear combustion rate by 10–15% compared to known analogues.
