Recently ceramic based composites have been developed for space and energy application. In such application, the materials must be impacted by high velocity objects. Since suitable high velocity impact-test systems applicable for ceramic-based composites are not developed, impact phenomena have not been clarified until now.The aim of this study is to develop a system applicable for ceramic-based composites with the following characteristics : (1) a projectile is accelerated with propellant, (2) velocity of various types of projectiles can be measured, (3) many types of ceramic-related composites can be used as the target materials, and (4) the products of the projectiles velocity and size is over 10 mm km/s.The characteristics of the developed system in this study is as follows : (1) propellant and helium are used as the acceleration force, (2) nylon sabot having 8mm-diameter and 20mm-length can be accelerated unto 2.5km/s, (3) the velocity of a 4mm-diameter steel and a ferrite ceramic sphere can be measured, (4) shock wave velocity and particle velocity can be measured, (5) impact behavior of target materials can be observed through windows, and (6) one person can be operate this system twice a day.

近年来，陶瓷基复合材料已被开发用于空间和能源应用。在这种应用中，材料必须受到高速物体的冲击。由于没有开发出适用于陶瓷基复合材料的高速冲击试验系统，因此至今还没有弄清楚冲击现象。本研究的目的是开发一种适用于陶瓷基复合材料的系统，该系统具有以下特点：（1）用推进剂加速射弹，（2）可以测量各种类型射弹的速度，（3）多种陶瓷基复合材料可用作靶材料;（4）弹丸速度和尺寸的乘积超过10 mm km/s。（1）用推进剂和氦气作加速力;（2）直径8 mm、长20 mm的尼龙弹托可加速到2.5km/s;（3）可测量直径4 mm的钢球和铁氧体陶瓷球的速度;（4）可以测量冲击波速度和粒子速度;（5）可以通过窗口观察靶材料的撞击行为;（6）一个人可以每天操作该系统两次。
