The Effect of Fiber on EPDM Inhibitor Material

Abstract:

In this paper, we studied the different content of aramid fiber, aramid pulp, carbon fiber, high silica fiber, mullite fiber, alumina fiber's effect on EPDM inhibitor material. The result show that aramid fiber can significantly improve the ablation resistance of thermal insulation layer, when the content of aramid fiber up to 6.7%,the inhibitor material's ablating rate get the minimum value 0.04mm/s. Aramid pulp can improve ablation resistance of thermal insulation layer, but its dispersion in insulation material is difficult. Others inorganic fiber can't lower the ablating rate as much as aramid fiber, it mainly because of the brittleness of inorganic fiber, during the dispersion process, most of fiber had been triturated, so those fiber can't decrease the liner ablation rate of the inhibitor.
