Ball milling time is an important factor that affects the rheological properties of shear thickening fluid (STF), which is rarely studied. In this study, SiO2 particles with a diameter of 500 nm and PEG 200 were mixed and milled for 4, 6, 8, 16, and 24 h in an omnidirectional planetary ball mill to obtain the corresponding shear thickening fluids (STFs). Through TGA, SEM, DLS, and other characterization methods, it was found that a long ball milling duration would lead to the surface breakage and wear of SiO2 in STF. The effects of STFs with different milling durations on the inter-yarn friction and puncture resistance of STF-Kevlar composites were also studied. The results show that the STFs produced with a ball milling time of 4 h or 6 h are not uniform, with some semi-solid lump remained. Compared with other milling time durations, the peak viscosity of STF with a milling time of 8 h can better improve the friction between yarns in the fabric and the fabric puncture resistance.
