Organic fiber 1,organic fiber 2,carbon fiber powder and nanoinorganic substance were added to HN
BR matrix respectively. By morphology analysis and Xray energy dispersive spectroscopy (EDS),the effect of different amount of different fillers on ablation performance and mechanical properties of HNBR was studied. It is foundthat HNBR with organic fiber 1 and nano inorganic substance possesses good ablation performance. HNBR with organic fiber 1 has poor mechanical properties,while nano inorganic substance have little impact on mechanical properties ofHNBR. HNBR with organic fiber 2 and carbon fiber powders has little impact on mechanical properties but unsatisfactory ablation performance.
