Processing Of Ceramic Composite Armor Technology Research

With the progress of science and technology, especially the increasing might of anti-tank weapons and the naissance of special type weapons, the higher requirements for protective performance of tank armors are put forward, which demand the superior antibullet performance as well as the properties of light weight, high maneuverability, antifragment, antiradiation etc. For high antibullet performance, light weight and low cost, the ceramic composite armor is widely applied in the bodywork and casemate structures of tanks and armored vehicles. Usually, according to the assembly requirements in the working place, the ceramic composite armor demands secondary machining, such as drilling, shaving, cutting, slotting, especially plenty of hole drilling. The ceramic composite armor related to this thesis is composed of aluminum alloy, glass fiber reinforced composite and engineering ceramics.The main contents in this thesis are made up of four portions. Firstly, based on the analyses of mechanical properties and machining mechanism of component materials of ceramic composite armor, the machining process is researched in detail, which makes the theory basis for the machining study. Secondly, through the orthogonal experiments, the parameters of diamond bits are optimized. The experimental results show that the diamond bit with optimal parameters could work with high efficiency. Thirdly, through plenty of experiments, the technological parameters are studied, and the influence relations of rotation speed versus machining efficiency and axial service load versus machining efficiency are presented, which gives the basis for the determination of technological parameters. Fourthly, the wear regularity of diamond bits versus engineering ceramics is investigated with large amounts of experiments. The wear varying trend of sintering diamond bit versus engineering ceramics, the relations of wear of diamond bit versus axial service load and machining efficiency versus axial service load are obtained, which is a guide to manufacturing diamond bits, improving efficiency and decreasing matrix wear and tool cost.
