The interfacial bonding between a series of bonding agents including polyhydroxy alcohols bonding agents (LBA-22,LBA-201,hyantoin/triazines composite bonding agents,neutral polymeric bonding agents and substituted amides and RDX were studied. Meanwhile,all of the bonding agents were used to prepare RDX-CMDB propellants.
