| Abstract: |
| In this paper theorems on homogeneous materials subjected to impingements and fatigue was quoted. Erosive behavior of C/phenolic materials applied to solid rocket nozzle throats was investigated. Analysis and calculation on a single substrate and substrate covered by a changing char layer was conducted respectively. Sum up the thermo-chtr cal erosion calculation and contrast with the test results, the qualitative and quantitative results of particle impingements were gained. |
