复合材料夹层结构在舰艇碰撞防护中的研究进展

为了提高舰艇的碰撞防护能力，已发展了各种舰艇碰撞防护方法。传统的碰撞防护手段会使舰艇重量大幅增加，影响舰艇总体性能。复合材料夹层结构的出现给舰艇碰撞防护结构设计提供了另外一条途径，成为近期国内外相关研究的热点。本文以舰艇碰撞防护为背景，从复合材料夹层结构的低速冲击实验方法、变形损伤机理、冲击吸能影响因素、分析研究方法等几方面进行回顾、总结和归纳，并对今后的研究方向进行展望。

Research progress of composite sandwich structure in ship collision protection

In this paper, various collision protection methods were presented to ameliorate naval ships' collision protective capability. Conventional collision protection methods may result in the increase of the ship's weight and reduction of its functional performance. Composite sandwich plates serve as a new approach to the design of the collision protection structure, and have become one of the hottest research topics worldwide. With naval ships' collision resistance as its academic background, this paper reviewed the recent advances in the areas of experimental methods, deformation damage mechanisms, energy absorption factors, analysis methods and offered suggestions of future research directions in composite sandwich plates.
