“…Thomas et al [14] was able to increase the ductility and ultimate strength of the TiO 2 /AP composite propellant by 181% and 7%, respectively, using Tepanol as the bonding agent. Pereira et al [15] successfully applied Tepanol and castor oil as the filler-binder bonding agent (FBBA) by factorial design to improve the modulus and hardness of the propellant and discovered that the best mechanical properties and processability could be obtained with the NCO/OH molar ratio of 0.86, FBBA total concentration of 0.25, and CO:Tepanol mass ratio of 0.75.…”

Bonding agents are an important type of additive that are used to increase the interfacial interaction in propellants. A suitable bonding agent can prevent the dewetting between the oxidant and binder, and thus effectively improve the mechanical properties of the propellant. In the current paper, the bonding mechanisms and research progress of different types of bonding agents such as alcohol amine bonding agents, borate ester bonding agents, aziridine bonding agents, hydantoin bonding agents, neutral polymer bonding agents, and so on, are reviewed and discussed. The evaluation methods of their bonding performances including molecular dynamic simulation, contact angle method, in situ loading SEM, characterization analysis, and mechanical analysis are summarized to provide design ideas and reference for future studies.
