Function of Carbon Materials Used in Solid Propellants and Their Action Mechanism

WANG Han,ZHAO Feng-qi,LI Shang-wen,GAO Hong-xu (Xi′an Modern Chemistry Research Institute,Xi′an 710065,China)  
The function in catalyzing combustion,action mechanism and action rules of carbon black,C_(60),fullerene soot,carbon fiber and carbon nanotube in solid propellants are summarized.It is found that the carbon black and C_(60) in double base(DB)or composite modified double base(CMDB) propellant can enrich catalyst,prevent catalysts from conglomerating and make double base systematic propellant produce plateau or mesa effect,the pressure exponent of double base systematic propellant reduce and the burning rate at low pressure of double base systematic propellant enhance evidently.The carbon fiber improves the conduction of heat exchange,increases intensity of propellant,enhances the burning rate of propellant and prevents propellant from cracking.The carbon fiber and carbon nanotube in propellant promote the decomposition of energetic material and enhance the burning rate of composite propellant. The development direction of the carbon materials used in solid propellants is prospected.
