Cleaned repeatedly with deionized water until filtrate pH value is 7, vacuum drying under conditions of filtrate then is placed in 55-60 DEG C, makes
Obtain acidifying graphite alkene；
It is 4.8-5.2 that dilute hydrochloric acid solution is added into absolute ethyl alcohol and adjusts pH value, then adds silane coupling agent and is configured to
Solute mass fraction is 2.5% mixed solution, and it is 1 that solid-liquid ratio is pressed into mixed solution:1 weight ratio adds acidifying graphite
Alkene, after ultrasonic disperse 30min, the mechanical agitation 2-3h under the conditions of temperature is 75-80 DEG C of water bath with thermostatic control, obtained reactant is used
Acetone cleaning after be filtered by vacuum, then with washes of absolute alcohol until filtrate pH value be 7, the vacuum drying under conditions of 85-90 DEG C,
Modified graphene is made.
Further, in preferred embodiments of the present invention, above-mentioned glass fibre is modified glass-fiber, the modified glass
The preparation method of glass fiber is：After glass fibre ultrasonic cleaning, dried under conditions of 125-130 DEG C, then add silicon
5-10min is stirred in alkane coupling agent, is dried under conditions of being placed in 80-100 DEG C, modified glass-fiber is made.
Further, in preferred embodiments of the present invention, above-mentioned curing agent is aromatic amine curing agent.
Further, in preferred embodiments of the present invention, above-mentioned aromatic amine curing agent is diethyl toluene diamine.
Further, in preferred embodiments of the present invention, above-mentioned diluent is the ring that viscosity is 150-200mpas
Oxygen tree fat.
Further, in preferred embodiments of the present invention, above-mentioned high-performance light composite material is included by weight
11 parts of 10 parts of 22 parts of 70 parts of compound resin, modified carbon fiber, glass fibre, the curing agent and 15 parts of diluent of meter.
