This work is devoted to the development of pyrotechnic delay mixtures from a titanium matrix reinforced with carbon nanotubes using a combination of preliminary mechanical activation and thermal explosion. The phase and structural transformations of the Ti-CNTs mixtures were analyzed by microscopy and X-ray diffraction. The combustion temperature is practically independent of pressure, it remains constant over the entire range of argon pressure. These delay compositions are not sensitive to different mechanical influences. It is proved that certain amount of CNTs added to delay composition can increase delay precision and further doing so achieved less temperature dependence. The retardant compositions BaCrO4 + Ti/CNT containing carbon nanotubes have the improved characteristics of the retardant composition, such as delay accuracy, combustion stability. The developed retarding compositions are safe in production and at all stages of circulation.
