摘要：
Two types of multi-phase shear-thickening fluids (STFs) are prepared by adding high modulus materials such as carbon nanotubes (CNTs) and Kevlar staple fibers to a nano SiO2 suspension system. The Kevlar plain fabric is reinforced via the "soak and dry" process, and the yarn pullout test is applied to STF/Kevlar composite fabrics to analysis of the enhancement of interfacial friction properties between yarns. The DIC method is used to measure the shear deformation state and to evaluate the shear deformation stiffness of the STF/Kevlar. The results show that the multi-phase STFs demonstrate stronger interfacial friction enhancement in higher interfacial friction energy absorption and shear deformation stiffness, and the multi-phase STFs with different add-phases have different friction enhancement mechanisms on the interface between yarns.
