Abstract
The invention relates to the technical field of carbon fiber treatment, in particular to a method for treating the surfaces of novel carbon fibers. The method includes the steps that the carbon fibers are subjected to oriented winding through a winding roller and dragged into a surface treating pool; a solvent, a strong-alkalinity compound, modified silicon oil and a chemical treating agent are added into the treating pool, and the carbon fibers pass through the treating fluid through staggered fiber dragging devices; the carbon fibers treated through the treating fluid are dragged to an ultrasonic device, and barbs on the surfaces of the carbon fibers are detected; the carbon fibers detected through the ultrasonic device are selectively treated, and if the number of the barbs of the carbon fibers does not meet the requirement, the carbon fibers are dragged into the treating pool again to be subjected to secondary treatment; if the number of the barbs of the carbon fibers meets the requirement, purifying collecting is carried out through a washing device. By means of the carbon fibers treated with the method, production of fiber webs is even, and convenience is brought to production; the content of Z-direction fibers of a carbon fiber needling preform manufactured through the treated carbon fibers is increased, the interlaminar shear strength of the carbon fiber needling preform manufactured through the treated carbon fibers is improved, and the needling preform also has good resin wettability and good heat-field evenness.
Description
Technical field:
The present invention relates to carbon fiber processing technology field, be specifically related to a kind of novel carbon fiber surface treatment method.
Background technology:
Carbon fiber is the fibrous carbon material that phosphorus content is greater than 90%, it has high-tensile strength, high stretch modulus, low-density, high temperature resistant, anti-yaw damper, anticorrosive, the premium properties such as high connductivity and thermal conductance, low-thermal-expansion self-lubricating and good biocompatibility, is desirable resistance to ablation, 26S Proteasome Structure and Function composite constituent element.At present, carbon fiber and composite thereof are mainly used in the aspects such as the manufacture of the hard-core technology industry such as aerospace, aviation, atomic energy and sports equipment.
As a kind of novel high-performance fiber, the net tire that carbon fiber superimposed fiber is made and the prefabricated component that carbon cloth is formed through acupuncture all have special high-temperature mechanics and thermal property, both all have the characteristics such as excellent elevated temperature strength, wear-resistant and high temperature resistant ablation, are therefore widely used in high temperature thermal field material.But due to carbon fiber self easily crisp, easily broken, the feature such as rigidity is large, elastic modelling quantity is little, collude with powerful poor between fiber, cause later stage production and processing inconvenience, therefore must carry out surface treatment to its carbon fiber and improve its surface-activity.
But traditional carbon fiber treatment process is coarse, the process of carbon fiber surface hangnail does not meet technological requirement, brings can cross trouble to post-processed.
Summary of the invention:
The object of this invention is to provide a kind of novel carbon fiber surface treatment method, its process after carbon fiber make net tire production evenly, be convenient to produce, Z-direction fiber content and the interlaminar shear strength of the carbon fiber needling preform using the carbon fiber after process to obtain all are improved, and needling preform also has good resin wettability and thermal field uniformity.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: its processing method:
Step one: carbon fiber wire is carried out orientation winding by being wound around roller bearing, carbon fiber wire is drawn in surface treatment pond;
Step 2: add solvent, strongly alkaline compound, modified silicon oil and chemical treatments in treatment pond, leads silk device by carbon fiber wire through treatment fluid by staggered;
Step 3: the carbon fiber wire through treatment fluid process is drawn to Vltrasonic device, detects carbon fiber surface hangnail;
Step 4: the carbon fiber wire after being detected by Vltrasonic device carries out selective process, if carbon fiber hangnail discrepancy of quantity closes requirement, again draws and carry out after-treatment to treatment pond; If carbon fiber hangnail quantity meets the requirements, carry out purification by cleaning device and collect.
Beneficial effect of the present invention: its process after carbon fiber make net tire production evenly, be convenient to produce, Z-direction fiber content and the interlaminar shear strength of the carbon fiber needling preform using the carbon fiber after process to obtain all are improved, and needling preform also has good resin wettability and thermal field uniformity.
Detailed description of the invention:
The present invention is described in detail.
In order to make object of the present invention, technical scheme and advantage clearly understand, the present invention is further elaborated.Should be appreciated that detailed description of the invention described herein only in order to explain the present invention, be not intended to limit the present invention.
This detailed description of the invention is by the following technical solutions: its processing method:
Step one: carbon fiber wire is carried out orientation winding by being wound around roller bearing, carbon fiber wire is drawn in surface treatment pond;
Step 2: add solvent, strongly alkaline compound, modified silicon oil and chemical treatments in treatment pond, leads silk device by carbon fiber wire through treatment fluid by staggered;
Step 3: the carbon fiber wire through treatment fluid process is drawn to Vltrasonic device, detects carbon fiber surface hangnail;
Step 4: the carbon fiber wire after being detected by Vltrasonic device carries out selective process, if carbon fiber hangnail discrepancy of quantity closes requirement, again draws and carry out after-treatment to treatment pond; If carbon fiber hangnail quantity meets the requirements, carry out purification by cleaning device and collect.
The beneficial effect of this detailed description of the invention: its process after carbon fiber make net tire production evenly, be convenient to produce, Z-direction fiber content and the interlaminar shear strength of the carbon fiber needling preform using the carbon fiber after process to obtain all are improved, and needling preform also has good resin wettability and thermal field uniformity.
The above, only in order to technical scheme of the present invention to be described and unrestricted, other amendment that those of ordinary skill in the art make technical scheme of the present invention or equivalently to replace, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of right of the present invention.
