Abstract: The present invention relates to the technical field of polymer composite materials, and specifically, to a shear thickening composite material, a preparation method therefor, and use thereof. According to the present invention, a solid composite material with shear thickening performance is prepared by limiting the types and contents of all components in raw materials. This composite material is kept soft and has a proper elastic shape under a normal state, and can be rapidly subjected to strain enhancement through local density increase when being rapidly and violently impacted or extruded, so that a significant shear thickening phenomenon is presented, namely this material is a hard solid when being impacted by an external force, then this material has an increasing strength with the increase of the external force, and this material restores to an original relaxed, soft, and elastic state when the external force is removed.
