Abstract:
Nacre is regarded as an excellent template for biomimetic materials because of its unique structure. The nacre-like laminated armor materials inspired from this highly complex multi-level laminated structure, have a combination of excellent strength, toughness and impact resistance. As a result, they have received extensive attentions in the field of bulletproof protection. At present, most researches of nacre-like laminated armor materials focused on the reason exploration and verification of the excellent properties, as well as the biomimetic synthesis in various materials. In this paper, the strengthening and toughening mechanisms, fabrication technology and protective properties of various nacre-like laminated armormaterials are reviewed. Firstly, the intrinsic and extrinsic mechanisms behind the excellent performance are reviewed, as well as various commonly used biomimetic techniques and mechanical properties. In terms of protective performance, the various ballistic tests and finite element analysis of the nacre-like laminated armor materials are mainly reviewed. Various studies have shown that the materials do have high strength, high toughness, and high fracture absorption work, etc., but more researches are needed to achieve more efficient biomimetic preparation and fine structure control.
