Abstract
The invention discloses a carbon fiber rod, which is made from the following raw materials of: by weight, 60-80% of carbon fiber, 5-10% of an inorganic nanometer powder, 20-30% of a resin and the balance being additives. A preparation method of the carbon fiber rod comprises the following steps of: mixing the carbon fiber, the inorganic nanometer powder and the resin in proportion, adding a proper amount of the additives with uniformly stirring, and adopting an extrusion moulding method to obtain the carbon fiber rod. The additives are a coupling agent, a promoter, a flexibilizer and a mold lubricant, and the total addition of the additives is less than or equal to 10%. The inorganic nanometer powder is TiO2, the particle size of which is 20-30nm. The resin is a vinyl resin or epoxy resin. The carbon fiber rod provided by the invention has good surface regularity, uniform appearance, excellent tensile strength and bending strength and high fiber volume fraction, is corrosion resistant and acid and alkali resistant, has a light weight, and has good flexibility.
Description
Technical field
The present invention relates to a kind of carbon fibre material, specifically is that a kind of surperficial regularity is good, has the carbon fiber rod of good tensile strength and flexural strength.
Background technology
Thomel (carbon fibre), as its name suggests, it not only has the intrinsic intrinsic property of carbon material, has the soft workability of textile fibres again concurrently, is fortifying fibre of new generation.Thomel can be processed into fabric, felt, seat, band, paper and other materials.Thomel did not generally use separately except that as the heat-insulating material during tradition was used, and how to join in the materials such as resin, metal, pottery, concrete as strongthener, constituted matrix material.The carbon fiber reinforced matrix material can be used as aircraft construction material, electromagnetic shielding and removes health substitute material such as electric material, artificial ligament and be used to make rocket casing, powership, industrial robot, leaf springs of car and drive shaft etc.
Summary of the invention
It is good to the purpose of this invention is to provide a kind of surperficial regularity, has the carbon fiber rod of good tensile strength and flexural strength.
Technical scheme of the present invention is achieved in that a kind of carbon fiber rod; In massfraction; Its raw material comprises thomel 60-80%, inorganic nanometer powder 5-10% and resin 20-30%, and all the other are additives, and the preparation method of said carbon fiber rod is with thomel, inorganic nanometer powder and resin proportional mixing; Stir after adding suitable additives, adopt extrusion process to obtain carbon fiber rod then.
Said additive is coupling agent, promotor, toughner and releasing agent, its total addition level≤10%.
Said inorganic nanometer powder is TiO
2, its particle diameter is 20-30nm.
Said resin is Vinylite or epoxy resin.
The invention has the beneficial effects as follows: carbon fiber rod of the present invention surface regularity is good, and outward appearance is even, tensile strength and flexural strength excellent property, the fiber volume fraction height, and corrosion-resistant, acid and alkali-resistance, in light weight, snappiness is good etc.
