Fiber reinforcement material based on liquid metal and preparation method thereof

Abstract

The invention discloses a fiber reinforcement material based on liquid metal. The fiber reinforcement material based on the liquid metal comprises a fiber reinforcement and the liquid metal, wherein the fiber reinforcement mainly plays a supporting role, and the external load is dispersed to all positions along the trend of fibers; the liquid metal fills the fiber reinforcement and plays a supplementary supporting role, the rigidity adjustment can be realized along with the change of the existence state, when the temperature is lower than the melting point of the liquid metal, the liquid metalexists in a solid state, and the rigidity of the material is the highest; and with the increase of temperature, the liquid metal gradually changes from the solid state to a liquid state, the rigidityof the material is gradually decreased, and the rigidity of the material is decreased to the minimum when the liquid metal completely exists in the liquid state. The invention further provides a preparation method for the fiber reinforcement material. The fiber reinforcement material and the preparation method thereof have the advantages that the rigidity of the obtained material can change continuously along with the change of the external temperature, the fiber reinforcement material is a good material with controllable rigidity and can be applied to various fields such as flexible robots and exoskeletons.

Description

technical field [0001] The invention belongs to the technical field of fiber skeleton materials, in particular to a liquid metal-based fiber skeleton material and a preparation method thereof. Background technique [0002] Fiber skeleton materials generally refer to a series of composite materials that use fibers as the internal skeleton and are filled with flexible substances on the outside. The network skeleton formed by the internal fibers can disperse the force on the material everywhere, and has high toughness, high strength and load-carrying properties. Good strength and other advantages, it has important applications in the fields of rubber products such as tires, tapes and hoses. In addition, different raw materials for constructing the fiber skeleton will have very different mechanical properties along different directions of the skeleton, which provides a simple idea for manufacturing anisotropic materials. [0003] Liquid metal has the advantages of good electric...
