Abstract: The baton is one of routine equipment for armed policeman ensuring public security. The inside of traditional baton is made of metal component. So the whole baton is heavy and cause hand vibrated, and even have a danger to hurt opponent. The novel composite baton was researched detailedly in this paper. Firstly, different configuration and manufacturing technology of composite as the component inside baton were investigated, and the form of cylindroid spiral spring was confirmed. The elasticity force, bend reversion rate and damping property of composite baton were also tested and analysed. Compared with traditional metal baton, composite baton not only conforms to international convention, but also has good performance.
