| Abstract: | The effect of chain extenders (CE) on mechanical properties of HTPB propellants is studied using tensile testing and other analysis tests.It is found that the effect of CE on mechanical properties of HTPB propellants is great and the microphase segregation is thought to be the main factor in improving the mechanical properties at low temperature. |
