Preparation method and application of carbon-fiber-reinforced macromolecule-based composite

Abstract

The invention discloses a preparation method and application of a carbon-fiber-reinforced macromolecule-based composite. A saline solution required by an inorganic compound is put in a reaction kettle, a base material used for inducting an alternating magnetic field is put in the reaction kettle, the reaction kettle is sealed and then put into water-heat induction heating equipment, then the reaction kettle is cooled to the room temperature, and the base material loaded with the inorganic compound is taken out to be cleaned and dried; and finally, hot press molding is conducted on the base material, and the carbon-fiber-reinforced macromolecule-based composite is obtained. According to the method and application, the water-heat induction heating technology is applied to surface grafting of a carbon fiber, and the defect that the carbon fiber cannot be combined with other components easily due to surface inertia of the carbon fiber is overcome. In addition, under the action of the alternating magnetic field, multiple kinds of nanometer materials are promoted to grow on the surface of the carbon fiber due to the high temperature of the carbon fiber, more engaged position points are provided for bonding of the carbon fiber and resin, and interfacial bonding of the carbon fiber and the resin and the mechanical performance of the composite are improved.

Description

【Technical field】

[0001] The invention belongs to the technical field of composite material preparation, and relates to a preparation method and application of a carbon fiber reinforced polymer matrix composite material. 【Background technique】

[0002] Carbon fiber is often used as a reinforcing material for polymer matrix composites because of its excellent comprehensive properties (high specific modulus and strength-to-weight ratio, low thermal expansion, high electrical conductivity, high thermal conductivity, wear resistance, and high temperature resistance, etc.) [Zhou Xiya Ed. Composite Materials. Beijing: Chemical Industry Press, 2005.01.]. However, due to the small surface energy of carbon fiber, poor wettability with the resin matrix, and poor interface bonding performance, the mechanical properties of the composite materials prepared by it are often different from the theoretical value [ChoiI, LeeDG. 2013;48:1-8.].

[0003] Therefore, proper treatment of the carb...
