The carbon fiber composite material core rod is the core of carbon fiber composite core wire.In the prior art, manufacture method be with unidirectional continuous carbon fibre, glass fibre jointly as reinforcing material,, form by process manufacturings such as resin-dipping, mold heated, mechanical tractions as matrix with epoxy resin and curing system thereof.Its shortcoming is in the carbon fiber composite material core rod, carbon fiber and glass fibre are unidirectional fibre, thereby its compressive strength and shear strength are low, easily brittle failure and splitting under coiling, distorting stress effect, cause fail safe to reduce, in addition, this carbon fiber composite material core rod does not have conducting function.
Summary of the invention
According to the technical problem of above-mentioned proposition, and provide a kind of carbon fiber composite material core rod and processing method thereof.The technological means that the present invention adopts is as follows:
A kind of carbon fiber composite material core rod, it is characterized in that: be provided with glass layer I and glass layer II at the carbon fiber core external surface, described glass layer I by some strand parallel with described carbon fiber core body and from around evenly coat described carbon fiber core body the one-way glass fiber consist of, described glass layer II is made of the some strands of glass fibres that axially evenly weave along described glass layer I.
Preferably, link into an integrated entity by epoxy resin adhesive curing between described glass layer I and described glass layer II and the described carbon fiber core body.
Preferably, be added with conductive powder in the described epoxy resin adhesive.
The present invention also provides a kind of processing method of carbon fiber composite material core rod, it is characterized in that comprising the steps:
1. under the effect of hauling machine, carbon fiber and segment glass fiber are entered in the resin storage tank that is full of epoxy resin solution, pass through again the preforming device behind the impregnating resin, carbon fiber is concentrated formed carbon fiber core body, glass fibre from coating equably described carbon fiber core body all around, form the moistening circular glass fibrage I of one deck, and enter mould;
2. by the Horizontal weave machine glass fibre that another part is continuous, sentence 25 ° of-45 ° of angles in die inlet and be woven on operating, the moistening carbon fiber core body with the glass layer I, form the glass layer II;
3. under the draw of hauling machine, enter mould through the carbon fiber core body with glass layer I and glass layer II after the braiding, through 160 ℃ of-230 ℃ of sclerosis, one-shot forming is the carbon fiber composite material core rod.
Compare than prior art, processing method provided by the invention is for making up by braiding and pultrusion two kind equipments, the technique of while and continuous operation is made the carbon fiber composite material core rod, carbon fiber core body, glass layer are reinforcing material in the plug of the present invention, epoxy resin adhesive is matrix, have that quality is light, high strength, high-modulus, low coefficient of linear expansion, conduction, the excellent properties such as ageing-resistant, in composite material manufacturing field, have higher technology content.Plug of the present invention is core and the key technology of making carbon fiber composite core wire ACCC (Aluminum Conductor Composite Core).
Glass layer provided by the invention is to form with the braiding of certain angle with continuous glass fibre, has significantly improved compressive strength and the shear strength of plug, the anti-roll that has effectively strengthened plug around and anti-torsion ability; In addition, the basis material epoxy resin adhesive is carried out modification, give the function of plug conduction, directly improved the transmission capacity of carbon fiber composite core wire.
The present invention has more excellent mechanical property and safety guarantee, improves the transmission line capability of carbon fiber composite core wire, and operating cost is low.
