Abstract
The present invention particularly relates to a pulling-extrusion section bar of assorted fiber and a processing method. Carbon fiber, glass fiber, modified resin of oxene group and flyash are mixed together, and then, pulling-extrusion processing is carried out; the pulling extrusion temperature is controlled to be from 120 to 140 DEG C, the speed is controlled to be from 0.5 to 1.5 meters/minute, the carbon fiber is from 0 to 30%, the glass fiber is from 0 to 60%, the modified resin of oxene group is from 0 to 40%, and the flyash is from 0 to 20%. The present invention solves the respective defects of the glass fiber and the carbon fiber and combines the advantages of the glass fiber and the carbon fiber together, the glass fiber can be better combined with resin, and the requirements for rigidity and strength of a member are satisfied; the present invention has the advantages of improved interlaminar capability of shearing resistance, cost control, cost reduction, engineering cost saving, structure weight reduction and various difficult overcoming during transportation, installation and use; part of the flyash is added in order to further reduce the cost on the basis of ensuring various items of data. The present invention has the advantages of very simple process, convenient operation and easy assurance of quality.
Description
Technical field
The present invention relates to fiber drawing and extruding section bar and processing method that a kind of civil engineering is used, particularly a kind of assorted fibre drawing and extruding section bar and processing method.
Background technology
Before the present invention, a large amount of polymer matrix composites that use in the civil engineering, as fiberglass, its fibrous material mainly is pure glass fibre, the section bar of producing is in light weight, intensity is high, decay resistance is superior, but cut defectives such as ability before, interlayer low owing to polymer matrix composites rigidity is anti-, limited its further application in technical field of civil engineering, particularly modern large scale civil engineering requires section bar to have the rigidity of stronger bearing capacity and Geng Gao, otherwise can't finish and guarantee these civil engineerings and safe operation; Along with science and technology development, the composite material field is also developed greatly, many performances different various resins and fibrous material have been developed and have produced both at home and abroad, as carbon fiber, Kafra fiber etc. having been arranged, epoxy resin, epoxy vinyl modified resin etc. have been arranged also in the resin field in fiber art; Wherein, carbon fibre composite not only has higher intensity and lower density than glass fiber reinforced plastics composite material, and have an elastic modelling quantity suitable with high-carbon steel, individual other or even high-carbon steel 2 times and more than, M601 carbon fiber stretch modulus as the exploitation of toray company has reached 588GPa, can more effectively improve the rigidity of its structure and reduce the structure own wt than fiberglass, but because present carbon fiber price is higher, every square metre reaches about 200,000 yuans, not that general civil engineering institute is receptible, thereby limited extensive use and research in its civil engineering.
Summary of the invention
Purpose of the present invention just is to overcome the defective of above-mentioned various section bars, development, exploitation a kind of new assorted fibre drawing and extruding section bar and processing method.
Technical scheme of the present invention is:
The civil engineering processing method of assorted fibre drawing and extruding section bar comprises step:
(1) carbon fiber, glass fibre, epoxy vinyl modified resin, flyash are mixed, its content is carbon fiber 6～30%, glass fibre 48～60%, epoxy vinyl modified resin 28～40%, flyash 0～20%, and each constituent content sum is absolutely;
(2) said mixture is carried out pultrusion processing, the pultrusion temperature is controlled at 120～140 ℃;
(3) pultrusion speed is controlled at 0.5～1.5 meter/minute.
Advantage of the present invention and effect have been to avoid glass fibre and carbon fiber defective separately, their advantages together, carbon fiber is used in main force part on the civil engineering member, use glass fibre in less important force part, and make that glass fibre and resin are better to be combined, the rigidity and the requirement of strength of member had both been satisfied, improve the shearing strength at intersection ability, may be controlled to this again, reduce price, save engineering cost, and reduce dead load, improve all difficulties in transporting, installing and using; Adding part flyash also is in order to guarantee that an enterprising step of every data basis reduces cost.Technology of the present invention is very simple again, and operation is also convenient, the quality assurance that is easy to get.
Description of drawings
Fig. 1---assorted fibre drawing and extruding section bar of the present invention " worker " word girder construction figure.
The specific embodiment
Embodiment 1:
Prescription: carbon fiber 6%, glass fibre 54%, epoxy vinyl modified resin 30%, flyash 10%; Carry out pultrude process processing after the mixing, the pultrusion temperature is controlled between 120～140 ℃, generally get 130 ℃ for good, temperature is crossed to hang down and can be made that adhesive property is very poor between the different fibers, have a strong impact on the mechanical property of section bar, temperature is too high then can be different with the coefficient of expansion between the glass fibre because of carbon fiber, and at the inner initial temperature pressure that produces of section bar, have a strong impact on the mechanical property of section bar, this is that work in-process must be noted that; Pultrusion speed is controlled at 0.5～1.5 meter/minute, generally gets 1.0 meters/minute for good, excessive velocities, also fully not bonding, can have a strong impact on the mechanical property of section bar between fiber and the resin, speed is low excessively, then can reduce speed of production, influence economic benefit, therefore will note especially excessive velocities.
The little beam section of " worker " word as shown in Figure 1, through detecting, the interlayer shear performance has improved more than 10%, rigidity improves more than 100%, cost be the carbon fiber drawing and extruding section bar 20% in addition less than.
Embodiment 2:
Prescription: carbon fiber 12%, glass fibre 48%, epoxy vinyl modified resin 30%, flyash 10%.Other are with embodiment 1.
Embodiment 3:
Prescription: carbon fiber 20%, glass fibre 50%, epoxy vinyl modified resin 30%, flyash 0%.
