Research on High Performance Organic Silicon Ablative Materials for Use in Solid Rocket Motors
Abstract
This Chinese translation discusses the effects of the structure of organic silicon resins (R/Si and Me/Ph molecule chain forms and comonomer structures) on the thermal stability of materials and ablative properties. Opting for the use of special composite techniques and precise formulation designs, it is possible to compound resins with structures that are linear and branched. They have small weight losses under heat. The char yield ratios are high. The charring layers have great strength, and anti-scouring properties are good. Using endothermic chemical reactions that occur at high temperatures between fillers in order to design materials for formulation, it is possible to effectively lower the cold wall temperature, improving ablative properties.
