Abstract: |
In this paper, how to enhance mechanical performances of EPDM rubber ablation insulation for SRM chamber is studied, the results show that adding viscosity resin and unsaturated metal carboxylic acid have good adding-strength effects on EPDM rubber insulation, stretch strength and elongation at break of EPDM rubber are evidently improved, as well as the influence mechanism of mechanical performances are analyzed. |
Key words: EPDM rubber ablation insulation;mechanical performances;improvement |
