Description
Technical field
The present invention relates to a kind of pultrusion tubing and preparation method thereof, particularly relate to a kind of fibre reinforced materials pultrusion tubing and preparation method thereof with braiding structure.
Background technology
With the fibre reinforced composites pipe of traditional pultrusion manufactured, owing to have only unidirectional longitudinally fortifying fibre, hoop intensity and transverse strength are not high, thereby when using as the corrosion-proof lining of pressure-resistant pipeline and metallic conduit, pressure-bearing is lower.Adopt the fibre reinforced composites tubing of fiber winding forming, though can obtain withstand voltage very high tubing by the winding angle design of different layers, processing cost is far above the manufacturing cost of pultrusion.Chinese patent CN1072631A discloses a kind of process for making fibre-reinforced drawn-extruded, be to have the heating pultrusion die of core to make it be solidified into vertical unidirectional fibre reinforced plastics pipe that internal diameter meets the requirements by a pair earlier pitch based fiber, then, on this plastic tube, carry out fleece-laying at this heating pultrusion mould and the second heating pultrusion between touching, after the second above-mentioned heated mould it is solidified, though this method has solved the problem of the horizontal intensity of fiber, but because increased manufacturing procedure, processing cost increases, in addition, between pultrusion pipe that ground floor has solidified and second layer winding pipe, lamination problem may occur, thereby influence the transverse strength of pultrusion tubing.
Summary of the invention
The object of the present invention is to provide a kind of intensity expensive low fibre reinforced composites pultrusion tubing and manufacture method thereof.
One of the present invention's fibre reinforced composites pultrusion tubing is achieved by the following technical solution:

Main enhancement layer with fibre reinforced materials of control of two-dimensional braided structure;
It between main enhancement layer and outer surface layer the long fibre layers of reinforcement of vertically arranging;
Outer surface layer with fabric reinforcing material.
The enhancing sleeve pipe that described main enhancement layer is continuous weaving Cheng Huan, the braid angle of its control of two-dimensional braided structure are 30～60 °, and the braided sleeving diameter of its fiber master enhancement layer (2) is 5～500mm.
Four layers of fibre reinforced materials of the tube wall of described pultrusion tubing are for being the fibre reinforced materials of matrix with the resin, and wherein the matrix resin material is thermosetting resin or thermoplastic resin; Described thermosetting resin is selected from a kind of of unsaturated polyester resin, vinyl ester resin, epoxy resin or phenolic resins; Described thermoplastic resin is selected from a kind of of nylon, polypropylene, ABS, Merlon, polysulfones, polyether sulfone, polyphenylene ether, PEEK or PPS.
The fiber of described main enhancement layer and long fibre enhancement layer fibre reinforced materials is selected from one or more in carbon fiber, glass fibre, aramid fiber, superhigh molecular weight polyethylene fibers, basalt mineral fiber, boron fibre, the metallic fiber.
The fabric of described interior surface layers and outer surface layer fibre reinforced materials is selected from one or more mixed fibrofelt, cloth and the paper in carbon fiber, glass fibre, aramid fiber, superhigh molecular weight polyethylene fibers, basalt mineral fiber, boron fibre, the metallic fiber.
Two of purpose of the present invention is to provide above-mentioned preparation method with fibre reinforced composites pultrusion tubing of control of two-dimensional braided structure.
The preparation method of the present invention's two fibre reinforced composites pultrusion tubing is achieved by the following technical solution:
At first select the pultrusion pipe mold: determine inside and outside die size according to the wall thickness of pultrusion tubing, outer mold is by 120 ° of spacing design muscle grooves, and the width dimensions of muscle groove is 2～5mm, highly is 1～5mm, and inner mold is that an end is the pipe with conical in shape transition; Design the dawn number and the radical of the fiber of control of two-dimensional braided then according to the required caliber of reinforced pipe, determine braid angle, continuous weaving master enhancement layer sleeve pipe on two dimension three axial braiders, after braiding was finished, main enhancement layer, interior surface layers, outer surface layer and long fibre enhancement layer were shaped to the tubing shape of design in advance by the preforming mould of pultrusion.After preformed tubing passed through the steeping vat impregnation simultaneously, make resin solidification through selected pultrusion die, the bringing-up section of mould is 2 sections or 3 sections gradient increased temperatures, and making the one-shot forming in same pultrusion die of preformed tubing is pultrusion tubing.
Fibre reinforced composites pultrusion tubing with control of two-dimensional braided structure of the present invention can also be shaped to round tube, rectangular tube, oval pipe and polygon pipe.
The present invention solves the low problem of pultrusion tubing transverse strength from the configuration aspects of braided sleeving, and pultrusion of all reinforcing fiber materials, has solved the interface debonding problem of different fiber reinforcing texture layers, significantly cuts down finished cost simultaneously.The pultrusion tubing of manufacturing both can be applicable to fiberglass and had carried fluid media (medium) or similar applications, also can be used for especially oil field oil pipe and high pressure water injection pipe etc. of corrosion-proof lining pipeline.
