Embodiment

[0019] A method for organically modified nanoparticles to reinforce carbon fiber resin-based composite materials. Firstly, organic modifiers are used to treat nanoparticles to produce a small amount of amino functional groups on the surface, and then combine them with low-viscosity resin components in the reinforced resin system. Mechanical stirring and ultrasonic dispersion to uniformity to form a nano-enhancer masterbatch; add the nano-enhancer masterbatch to the resin system in a certain proportion, so that the mass percentage of nanoparticles in the entire resin system is 0.1% to 10%, and add nano-enhancer The resin system of the agent masterbatch is compounded with carbon fiber to prepare a carbon fiber resin matrix composite material.

[0020] The organic modifier adopts one or a mixture of cetyltrimethylammonium bromide, dihexadecyldimethylammonium bromide, 3-hexadecylammonium bromide, and silane coupling agent . The nanoparticles are one or a mixture of nano-montmoril...

Abstract

The invention provides a method for enhancing a carbon fiber resin based composite material through organic modified nano-particles. The method comprises the following steps: firstly processing nano-particles by virtue of an organic modifying agent to generate amino groups on the surfaces of the nano-particles, mechanically stirring the nano-particles with low-viscosity resin components in an enhanced resin system, and carrying out uniform ultrasonic dispersion, so as to form enhanced nano-master batch; adding a nano-enhancer into the resin system in a certain proportion, compounding the resin system with carbon fibers, so as to prepare the composite material. According to the method, a nanometer effect of the nano-particles is exerted when the rigidity of the nano-particles is adequately utilized, so that the compression strength of the resin system composite material is effectively improved, and meanwhile, the system has excellent impact resistance and can be applied to the aviation market with extremely high requirements on the impact resistance of the composite material.

Description
