The paper reviews the current research status of rubber elastomer materials and reinforcement materials for flexible joints of solid rocket motor.It can be seen that rubber elastomer materials have two main development directions:low-modulus elastomer materials and wide-temperature-range elastomer materials.For reinforcement materials,our main focus is on using composite materials in order to simplify the structural design of flexible joints and reduce quality.The three moulding technologies of flexible joints,namely cold bonding moulding,hot bonding moulding and injection moulding,are introduced.It is proposed that injection moulding,which is capable of forming flexible joints with high speed,high precision and high reliability,is the future development trend of flexible joints manufacturing technology.
