The carbon fiber is microcrystalline graphite material prepared from a natural fiber by carbonization and graphitization treatment. The invention has the beneficial effects that carbon fiber composite compound provided by the invention remains small coefficient of thermal expansion in a wide temperature span range, has the characteristics of high strength, high temperature resistance, corrosion resistance and fatigue resistance; and the composite compound prepared from carbon fiber and silicic acid fiber has the characteristics of strong compression resistance and durability.
Description
Technical field
The present invention relates to carbon fiber complex chemical compound.
Background technology
Carbon fiber complex chemical compound be complex chemical compound is applied more extensive, a kind of complex chemical compound that performance is comparatively excellent, its specific tenacity, specific modulus overall target, existing structure material is the highest, having the field of strict demand in density, rigidity, weight, fatigue characteristic etc. and requiring the occasion that high temperature, chemical stability are high, carbon fiber complex chemical compound all has much advantage.
But every general character of the thermal expansion of existing carbon fiber complex chemical compound is poor, the coefficient of expansion of elastomerics under multiple temperature condition changes greatly, and under lower temperature conditions, molecular rupture, produces thermally splitting.
Summary of the invention
In view of the defect that prior art exists, it is an object of the invention to provide a kind of less at bigger temperature span scope thermal expansion coefficient, there is the carbon fiber complex chemical compound of high flexibility, high strength.
For achieving the above object, the technology used in the present invention solution: a kind of carbon fiber complex chemical compound, its composition comprises carbon fiber, epoxy resin, silicate fiber, polyethylene and auxiliary agent, described carbon fiber is the micro crystal graphite material obtained through carbonization and graphitization processing by natural fiber, described auxiliary agent comprises toughener, toughner, antioxidant, antiseptic-germicide and thermo-stabilizer, described toughener is boron fibre, described toughner is liquid polyester rubber, described antioxidant is to second phenol and dicyclopentadiene butylation product, described antiseptic-germicide is manganese oxide, described thermo-stabilizer is Dythal.
Described complex chemical compound composition by quality proportioning is: carbon fiber accounts for 35-48%, and epoxy resin accounts for 16-22%, and silicate fiber accounts for 12-16%, polyethylene accounts for 8-12%, toughener 3-5%, and toughner accounts for 2-4%, antioxidant 1-3%, antiseptic-germicide account for 1-2%, and thermo-stabilizer accounts for 2-3%.
Described complex chemical compound composition is preferably by quality proportioning: carbon fiber accounts for 44%, and epoxy resin accounts for 20%, and silicate fiber accounts for 14%, and polyethylene accounts for 10%, toughener 4%, and toughner accounts for 3%, and antioxidant 2%, antiseptic-germicide account for 1%, and thermo-stabilizer accounts for 2%.
The mean diameter of described carbon fiber is 10 48nm, and mean length is 5 15um, fibre density: 1.74-1.79G/cm, elongation (%) >=1.5, carbon content: >=95%, in the temperature range of-60 DEG C 248 DEG C, average coefficient of linear expansion is less than 100ppm/k.
The invention has the beneficial effects as follows: the present invention provides a kind of carbon fiber complex chemical compound, less thermal expansivity is still kept within the scope of bigger temperature span, there is the characteristics such as intensity height, high temperature resistant, corrosion-resistant and resistance to fatigue be good, the complex chemical compound being mixed with carbon fiber and silicate fiber, also has that resistance to compression is strong, the characteristic of durable.
