1) graphene oxide is taken, the graphene oxide water solution that concentration is 0.05-5mg/ml is made into, is with ultrasonic power
The ultrasonic device ultrasound of 300-1000W 10-60 minutes；
Carbon cloth being fitted in container bottom, then by step 1) the good graphene oxide water solution of ultrasound uniformly falls
Enter in said vesse, then the bubble in carbon cloth is driven out of and carbon cloth is fitted in container bottom, afterwards by container
It is put into baking oven, 80 DEG C of dryings 24 hours；
The carbon cloth surface for having graphene oxide in deposition afterwards uniformly applies and is covered with epoxy resin layer, obtains final product composite
Unit；
2) by laminating technology after, by the hot pressing 2 in the case where temperature is 150 DEG C and pressure is 5MPa of multi-layer composite materials material unit
Hour, obtain final product described orientation graphene oxide modified carbon fiber composite.
The orientation graphene oxide modified carbon fiber composite that the present invention is provided is by natural subsidence technique, without having
Machine solvent, by the affinity of the functional group of graphene oxide its own face so that graphene oxide orientation is simultaneously mutually firm to be obtained
It is combined together, one layer of barrier film of densification is formed in carbon fiber surface, then together with being compound to epoxy resin with laminating, most
Solidify afterwards obtain composite product.
Principle of the invention is as follows：This technology by natural subsidence technique, without organic solvent, by graphene oxide from
The affinity of the functional group on body surface so that graphene oxide orientation is simultaneously mutually firm must to be combined together, in carbon fiber surface
One layer of barrier film of densification is formed, so as to improve the impermeabilisation ability of carbon fibre composite.
For in prior art before relatively, the invention has the advantages that：
The present invention by natural subsidence technique, without organic solvent, by the functional group of graphene oxide its own face
Affinity so that graphene oxide orientation and it is mutually firm must be combined together, carbon fiber surface formed one layer of densification every
From film, so as to improve the impermeabilisation ability of carbon fibre composite.
