Description
Technical Field
The utility model relates to a strengthen the core, especially relate to an inside is provided with aramid fiber's strengthen core.
Background
In the prior art, the reinforcing core is aligned with the glass fiber reinforcing core, and the glass fiber reinforcing core has the defects of high brittleness, poor tensile resistance and bending resistance, no moisture-proof layer, poor moisture-proof performance of the reinforcing core and reduced service life of the reinforcing core.
SUMMERY OF THE UTILITY MODEL
The utility model provides a technical problem provide an inside is provided with aramid fiber's enhancement core, sets up the dampproof course in aramid fiber's outside, has solved enhancement core stretching resistance and bending resistance can be poor, does not have the dampproof course for the dampproof course of enhancement core is poor, has reduced the life's of enhancement core problem.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an inside is provided with aramid fiber's reinforced core, reinforced core includes middle base member, middle base member includes aramid fiber tow, aramid fiber tow passes through the adhesive bonding solidification and forms cylindric base member, cylindric base member outside has set gradually dampproof course and outer protective layer, first spiral groove has been seted up on the outer protective layer surface, the second spiral groove has been seted up to one side in first spiral groove, the cross-section in first spiral groove and second spiral groove is semi-circular, and all is provided with round chamfer between semicircular both ends and the core.
Further, the method comprises the following steps: the adhesive is coated on the outer surface of the fiber bundle to form a solidified layer.
Further, the method comprises the following steps: the outer protective layer is a polyolefin protective layer.
Further, the method comprises the following steps: the moisture-proof layer is a non-woven fabric layer.
The utility model has the advantages that: through the inside aramid fiber bundle that sets up at the enhancement core through the adhesive bonding solidification formation cylindric base member make the stretching resistance and the bending property of enhancement core better, the adhesive can be epoxy, the poor problem of moisture resistance has been solved to the dampproof course that cylindric base member outside set gradually, has reached the effect that improves the stretching resistance and the bending property of enhancement core for enhancement core life is longer, first spiral groove and the second spiral groove of seting up on the surface of outer protective layer, and the semicircle of first spiral groove and second spiral groove cross-section has reduced core cross sectional area, has reached the effect that has increased the bending strength of enhancement core.
Drawings
Fig. 1 is a schematic view of a reinforcing core with aramid fibers disposed therein.
Labeled as: the anti-moisture anti-corrosion coating comprises a middle matrix 1, aramid fiber bundles 2, a moisture-proof layer 3, an outer protection layer 4, a first spiral groove 41 and a second spiral groove 42.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1, the reinforcing core internally provided with aramid fibers comprises a middle base body 1, the middle base body 1 comprises aramid fiber bundles 2, the aramid fiber bundles 2 are bonded and cured by an adhesive to form a cylindrical base body, a moisture-proof layer 3 and an outer protection layer 4 are sequentially arranged outside the cylindrical base body, a first spiral groove 41 is formed in the surface of the outer protection layer 4, a second spiral groove 42 is formed in one side of the first spiral groove 41, the cross sections of the first spiral groove 41 and the second spiral groove 42 are both semicircular, and round chamfers are arranged between the two semicircular ends and the core body; through the inside aramid fiber tow 2 that sets up at the enhancement core through the adhesive bonding solidification formation cylindric base member make the stretching resistance and the bending property of enhancement core better, the adhesive can be epoxy, and the moisture barrier 3 that cylindric base member outside set gradually has solved the poor problem of moisture resistance, has reached the effect that improves the stretching resistance and the bending property of enhancement core for it is longer to strengthen core life, and first spiral groove and second spiral groove seted up on the surface of outer protective layer, and the semicircle of first spiral groove and second spiral groove cross-section has reduced core cross sectional area, has reached the effect that has increased the bending strength of enhancement core.
On the basis, as shown in fig. 1, the adhesive is coated on the outer surface of the fiber bundle to form a cured layer, so that the fibers in the fiber bundle 2 can move relatively.
On the basis, as shown in fig. 1, the outer protective layer 4 is a polyolefin protective layer, and compared with the traditional material, the polyethylene protective layer pipe has the characteristics of high mechanical strength, impact resistance, environmental stress cracking resistance, corrosion resistance, low temperature resistance, strict sealing, no leakage, long service life and the like.
On the basis, as shown in fig. 1, the moisture-proof layer 3 is a non-woven fabric layer, so that the non-woven fabric has good moisture absorption performance, and the strength of the reinforcing core can be further improved.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
