Abstract: |
A type nozzle liners of solid rocket motor (SRM) requires the properties of ablation resistance, scour resistance and heat insulation. Using the excellent temperature resistance and high carbon residue ratio of boron phenolic resin, a carbon fiber/boron phenolic lining with excellent performance is developed by optimizing and improving the formulation and process. The carbon fiber/boron phenolic lining has passed the high and low temperature cycle, the thermal impact test and the test run. The results show that the developed carbon fiber/boron phenolic lining has reliable properties and the technological properties meet the requirements. |
Key words: boron phenolic resin;carbon fiber reinforced boron phenolic composite;SRM integration molding liner |
