| Abstract: | The interface bonding in solid rocket motors is a very important condition to the grainconstruction integrity. In this paper, the interface bonding between case and insulation in motors is researched and four types of debonds between case and insulation are often seen in motors. These interface debonds are critical damaging to safe reliability of motors. The reasons for every type of debondsare demonstrated by analyzing with gas chromatography, nondestractive testing and dissection. Basedon experiments, technical preventatives of the debonds are given. The investigation results show thatthese technical measures are quite available to development of motor grains. |
