Problems solved by technology

However, due to the existence of π-π bonds and large van der Waals forces between graphenes, graphene is prone to agglomeration when it is used as a reinforcement phase of composite materials, which makes the dispersion of graphene in the prepared composite materials uneven, which seriously affects the composite material.

Abstract

The invention relates to a preparation method of a graphene-toughened-resin-based carbon fiber composite. According to the method, firstly, graphene and a low-viscosity reactive dispersing agent are subjected to ultrasonic dispersion, a graphene dispersing solution is prepared and then is mixed with resin, toughened resin in certain concentration is formed through mixing, then graphene-toughened carbon fiber prepreg is prepared through continuous impregnation and drying with the carbon fiber prepreg preparation technology, and the required graphene-toughened-resin-based carbon fiber compositeis prepared through laying, mold pressing and solidifying. The graphene-toughened-resin-based carbon fiber composite is high in toughness, the graphene dispersion performance is good, the structure iscomplete, the dispersing agent has the low viscosity and the characteristic of capability of cross-linking reaction, so that graphene can enter the space among carbon fiber bundles along with the resin, the binding force among the fibers can be increased, and the method is widely applied in the field of reinforced resin composites.

Description

【Technical field】 [0001] The invention relates to the field of composite materials. The intercalation effect of graphene is utilized, and the low viscosity and reactivity characteristics of the dispersant are used to allow graphene to infiltrate between carbon fiber fibers, thereby improving the strength of the composite material, especially the effect of toughening, specifically In other words, it is a preparation method of graphene toughened resin-based carbon fiber composite material. 【Background technique】 [0002] Graphene is a carbon atom sp 2 Composed of hybrid orbitals, the hexagonal honeycomb lattice planar film has a thickness of only 0.334nm, and the quasi-two-dimensional planar crystal structure of graphene with only one atom thickness and the in-plane conjugated π electron system make graphene have excellent properties. Electrical, thermal and mechanical properties. However, due to the existence of π-π bonds and large van der Waals forces between graphenes, gr...
