Abstract
The invention relates to a preparation method for a carbon fiber composite material. The main preparation steps include: material selection, material mixing, carbon fiber prefabrication, impregnation, heat treatment, and curing. The carbon fiber composite material involved in the invention has the advantages of excellent tensile strength and breaking elongation, easy large area integral molding, and stable molding.
Description
Technical field
The present invention relates to a kind of preparation method of matrix material, relate in particular to a kind of preparation method of carbon-fibre composite.
Background technology
The appearance of carbon-fibre composite, has improved thermal expansivity, fracture toughness property, impelling strength, electrical property, the magnetic property of single metal material greatly, thereby is widely used in the sophisticated technology industries such as military project, space flight.But in the performances such as conventional its tensile strength of CB/PVC material and elongation at break, go back Shortcomings, overall performance is had to larger impact.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the invention provides a kind of carbon-fibre composite, this carbon-fibre composite has good tensile strength and elongation at break, easily big area global formation, stable molding.Concrete technical scheme is:
The present invention adopts following steps to prepare carbon-fibre composite:
(1) by parts by weight, be that the viscose fiber of 50 ~ 60 parts, the rayon fibers that parts by weight are 25 ~ 30 parts, the pitch that parts by weight are 15 ~ 20 parts pass through dry mixed, then by batch mixing wire drawing, in air, heat, temperature maintains 200 ℃ ~ 300 ℃ and continues 50 minutes, then in inert atmosphere, be heated to 1200 ℃, maintain 20 minutes, then in inert atmosphere, be heated to 2500 ℃, maintain 15 seconds;
(2) carbon fiber making is immersed to the steeping vat of filling epoxy resin by transmission mechanism; Dipping time is controlled at 10s ~ 20s;
(3) then the carbon fiber having flooded is sent in heating unit and is cured, be 10min ~ 20min set time, and solidification value is 120 ℃;
(4) after epoxy resin cure, send out heating unit, take out goods.
Preferred version, described rare gas element is high pure nitrogen.
Preferred version, described heating unit is infrared-ray oven.
The carbon-fibre composite that the present invention can make through above-mentioned steps, this matrix material has good tensile strength and elongation at break, easily big area global formation, stable molding.
