Abstract

The invention discloses a method for preparing a composite reinforcement by taking plant fibers as a template. The method specifically comprises the following steps: modifying the surfaces of plant fibers by adopting 2-acrylamide-2-methylpropanesulfonic acid; mixing the plant fibers with a metal salt solution; adding sodium ethylene diamine tetracetate and an ammonia water solution for reaction; after the reaction is finished, mixing the prepared solid with a mixed solution of magnesium nitrate, strontium acetate and aluminum nitrate, adding a sodium hydroxide solution for reaction, drying theprepared solid after the reaction is finished, performing carbonization treatment in a muffle furnace to prepare a composite reinforcement, and mixing the composite reinforcement with a metal matrixto prepare the composite material. The method is simple to operate, the prepared composite material is high in strength and good in toughness, and sound interface bonding is achieved between the reinforcement and the metal matrix.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a method for preparing a composite reinforcement using plant fibers as a template and its application in metal matrix composite materials. Background technique [0002] With the development of modern science and technology, higher and higher requirements are put forward for the comprehensive properties of metal materials. In addition to good mechanical properties, the processing requires materials to have good comprehensive properties, such as wear resistance and fatigue. High performance toughness. Traditional single materials can no longer meet the needs of development, so it is necessary to compound different types of materials together to maximize their strengths and avoid their weaknesses to obtain materials with excellent performance, that is, composite materials. A composite material is a multiphase solid material composed of two or more substances with different physic...
