高阻尼材料既具有结构材料的良好力学性能，又具有高阻尼减振能力，是目前普遍认为的最直接的减振解决方案。然而，在金属和合金中，同时表现出高阻尼能力和良好的机械性能通常是不相容的，因为负责内部摩擦（即阻尼能力）的微观机制取决于控制机械强度的参数。为了实现折衷，最重要的方法之一是开发两相复合材料，其中每一相都扮演着特定的角色：阻尼或机械强度。本文综述了高阻尼复合材料设计概念的发展及其制备和性能（包括力学性能和阻尼性能）的研究，提出了一种新的高阻尼复合材料的设计概念，其中硬质陶瓷添加剂在室温下由于应力而表现出高阻尼能力，高密度点缺陷在陶瓷相中的诱导再取向和复合材料的高阻尼能力主要来自陶瓷相。
Nowadays it is commonly considered that high damping materials which have both the good mechanical properties as structural materials and the high damping capacity for vibration damping are the most direct vibration damping solution. In metals and alloys however, exhibiting simultaneously high damping capacity and good mechanical properties has been noted to be normally incompatible because the microscopic mechanisms responsible for internal friction (namely damping capacity) are dependent upon the parameters that control mechanical strength. To achieve a compromise, one of the most important methods is to develop two-phase composites, in which each phase plays a specific role: damping or mechanical strength. In this review, we have summarized the development of the design concept of high damping composite materials and the investigation of their fabrication and properties, including mechanical and damping properties, and suggested a new design concept of high damping composite materials where the hard ceramic additives exhibit high damping capacity at room temperature owing to the stress-induced reorientation of high density point defects in the ceramic phases and the high damping capacity of the composite comes mainly from the ceramic phases.
