A mini ball acceleration system was developed for the study of dynamic fracture of ceramic and single crystal materials. This system consists of (1) low pressure gas gun, (2) sabot assembly, (3) stopper block with plastic membrane for second acceleration, (4) velocity measurement device for sabot and ball, and (5) enclosed target box. The plastic sabot assembly houses steel plunger and the void filled with silicone rubber. The sabot is stopped by the stopper block then the steel plunger inside the sabot compress the silicone rubber to high pressure to rupture the plastic membrane. Then the compressive energy of the silicone rubber is transferred to the ball. More than ten times of initial speed was attained. Non-contact velocity measurement system is measuring the supersonic speed of the mini ball. Maximum speed up to 1200m/s for plastic and 700m/s for steel ball was attained. Perforation test of glass window was successfully done by the developed impact system.
