Processing technology and ballistic-resistant mechanism of shear thickening fluid/high-performance fiber-reinforced composites: A review

Shear thickening liquid (STF) is a reversible phase change material that can realize ?liquid-solid? transformation when subjected to high-speed impact shear, and return to the liquid state after impact disappearance. Combined with high-performance fiber, it can be made into a ?liquid protection device?. STF/ highperformance fiber composite materials are flexible and lightweight with intelligent mechanical response and energy absorption mechanism. This article introduces the ballistic-resistant mechanism and properties of STF/ high-performance fiber composites. Various factors affecting ballistic impact property are also discussed to better understand the ballistic impact process and the reaction mechanism of materials. Different characterization methods of ballistic properties have also been considered to provide some new ideas for the research, development, and application of flexible and intelligent ballistic materials with high responsiveness.
