Study on Mechanical Property and Structure of Water Erosion Triple Base Propellants

摘要

The water immersion technique is conducted to increase the surface area of the triple base propellant. In order to investigate the influence of water erosion on triple base propellants, the SEM and material tester were used to observe the surface texture and test the mechanical property at different temperature. The result shows that the effect of water erosion on structure is superficial, the erosion depth is about 50～150 μm after 60 minutes, which does not impact the interior structure. The tests of mechanical property indicate that the mechanical property declines with the time of water erosion increasing, the decrease at room temperature is less than the decrease at high and low temperature.
