Abstract In this work, shear thickening fluid (STF) was fabricated and encapsulated by using three different encapsulation methods for the first time. The mechanical properties of individual STF capsules were investigated to obtain optimal encapsulation method and formula. Much more energy can be absorbed for STF capsules during impact than that of quasi-static compression. The introduction of ultraviolet (UV) curable resin can significantly improve the static strength of STF capsule and thus enhance the handleability of STF capsule. The STF capsules synthesized through the two-step polymerization method show an elastic shell which can stand multiple impacts without any damage. This STF capsule possesses higher static strength and absorbs more strain energy than capsules synthesized through the other two methods. Furthermore, incorporation of the STF capsules into silicone gel enhances the energy absorption capacity of matrix material up to 71.3%.

剪切增稠流体包封技术优化及包封胶囊与聚合物复合材料的动态响应

摘要 在这项工作中，首次使用三种不同的封装方法制备和封装了剪切增稠液（STF）。研究了单个 STF 胶囊的机械性能，以获得最佳的封装方法和配方。与准静态压缩相比，STF 胶囊在撞击过程中可以吸收更多的能量。紫外线（UV）固化树脂的引入可以显着提高STF胶囊的静态强度，从而增强STF胶囊的可操作性。通过两步聚合法合成的 STF 胶囊具有弹性外壳，可以承受多次冲击而不会造成任何损坏。与通过其他两种方法合成的胶囊相比，这种 STF 胶囊具有更高的静态强度并吸收更多的应变能。此外，
