Existing defects：Compressive strength lifting effect of the first way for fibre reinforced composites is limited；It is fine in the second way
The laying of dimension and mix compressive strength lifting effect for fibre reinforced composites also and unobvious, and three-dimensional woven is set
Standby expense is sufficiently expensive, substantially increases the production cost of fibre reinforced composites.In addition, at present both at home and abroad on the company of raising
The patent that continuous fibre reinforced composites are compressed axially performance is also less.
Utility model content
For in the prior art the defects of, the main purpose of the utility model, which is to provide one kind, can improve continuous lod
The enhancing bundle of composite fibers of composite material axial direction compression performance.

Reinforcing fiber bundles composition fiber be high-modulus inorfil, the fiber that high-modulus inorfil is made of inorganic material, and
And its modulus is not less than 176cN/dkex.In this way, by being in one layer of winding fibre bundle of reinforcing fiber bundles surface wrap simply
The compressive strength of former reinforcing fiber bundles and compression performance can be greatly improved.
Further, the material of reinforcing fiber bundles described in above-mentioned enhancing bundle of composite fibers be carbon fiber, it is glass fibre, profound
One or more mixing in military rock fiber.
Further, the composition fiber that fibre bundle is wound described in above-mentioned enhancing bundle of composite fibers is polypropylene fiber, superelevation
One or more mixing in molecular weight polyethylene fiber, polyparaphenylene's benzo dioxazole fiber.
Further, fibre bundle is wound described in above-mentioned enhancing bundle of composite fibers to be a plurality of, every winding fibre bundle is increasing
The angle of the helical angle of strong fibre bundle perficial helical winding is 30-75 °.The definition of helical angle：Cylinder where reinforcing fiber bundles
It is sharp folded by between the tangent line for the helix that winding fibre bundle is wound and the cylindrical surface straight edge line for passing through point of contact on surface
Angle.
Further, every winding fibre bundle is wound in reinforcing fiber bundles perficial helical in above-mentioned enhancing bundle of composite fibers
Helical angle is identical.It is parallel between each other that can be interpreted as every winding fibre bundle.
Further, described in above-mentioned enhancing bundle of composite fibers it is a plurality of winding fibre bundle every between at intervals of 2-
6mm.This is to further improve the compressive strength and compression performance of enhancing composite material.
Further, fibre bundle is wound described in above-mentioned enhancing bundle of composite fibers includes two winding fibre bundles：First twines
Around fibre bundle and the second winding fibre bundle；The first winding fibre bundle is equal with the distance between the second winding fibre bundle.
Further, reinforcing fiber bundles described in above-mentioned enhancing bundle of composite fibers are per the enhancing of Shu Hanyou 1000-12000 roots
Fiber, the specification of the reinforcing fiber is 594-7200 denier；The every Shu Hanyou 50-200 root reinforcing fibers of winding fibre bundle,
The specification of the winding fiber is 5-50 denier.
In conclusion enhancing bundle of composite fibers provided by the utility model in the winding of reinforcing fiber bundles outer surface by winding
Fibre bundle so that strengthen composite material compressive strength and compression performance can more former reinforcing fiber bundles improve 15-45%, the party
Method is simple to operation, and production equipment cost is low, can be easy to popularity, obtains high-performance fiber using simple method, is
High-performance textile material field provides a kind of new way.
