- Rheological characterization and synergistic energy absorption under fluid–solid interaction of shear thickening gel/3D angle interlocking composites Zixuan Liu Yuwei Zhao Xiayun Zhang Hongwei Tian Bao Shi Zhenhong Chen Lixia Jia Yuefen Han Sainan Wei Ruosi Yan Polymer Composites AbstractThis study reveals the impact resistance of shear thickening gel (STG) impregnated four‐layer regular angle interlocking fabrics (AIF) composites. The effects of STG parameters, including reaction time, reaction temperature, and reaction ratio, on the rheological characterization and mechanical properties of STG/AIF flexible composites were investigated. The results show that the increase in STG parameters accelerated the formation of BO crosslink bonds within the STG. The energy storage modulus of STG increased by three orders of magnitude for a reaction temperature of 230°C, a reaction time of 9 h, and a reaction ratio of 12.5%. STG had an obvious shear thickening effect. The coupling effect of STG and AIF increases the inter‐yarn friction. The shear thickening effect of STG and the deformation of AIF fabric synergistically absorbed the impact energy, and the energy absorption rate reached 95.6%. The material surface was not significantly damaged after the low‐velocity impact. The STG/AIF flexible composites showed excellent impact energy absorption properties.Highlights A new high‐energy absorption and impact resistance composite was prepared. Increased STG reaction ratio and temperature promoted its internal reaction. B and O atomic interactions enhance the rheological properties of STG. STG and fabric synergistically improve the impact resistance. 10.1002/pc.28396 http://onlinelibrary.wiley.com/termsAndConditions#vor
