Optimum optimization is obtained using with performance, can not only save a large amount of material, but also there is more excellent mechanical property and change
Performance, but circumferential and axial stress cannot be improved simultaneously and use denaturation energy.A kind of continuous fibre of patent CN201310123058
The production method and wind of dimension winding enhancing thermoplastic pipe, the patent of invention provide a kind of continuous fiber winding enhancing heat
The production method and wind of plastic tube, belong to pipeline production technical field.It solves existing continuous fiber winding and increases
Heat-flash plastic tube be easy to cause the secondary damage of continuous fiber to generate filoplume or fracture during the preparation process, reduces continuous fiber
Performance, the slickness of the pipeline outer wall of preparation and the problem that the robustness of pipeline is poor, strength character is unstable.
A kind of high temperature resistant of CN201410038369, high pressure resistant enhancing thermoplastic composite tube and its process units disclosure of the invention are a kind of resistance to
High temperature, high pressure resistant enhancing thermoplastic composite tube successively include inner tube, enhancement layer, outer tube from inside to outside；Said inner tube and enhancement layer
Between be provided with internal insulation, outer heat insulation layer is provided between the enhancement layer and outer tube.CN201120466107 is a kind of continuous
The multiple pipe of fiber prepreg tape winding enhancing
The patent includes tube wall outer layer and tube wall internal layer, and compound setting is by continuous glass between the tube wall internal layer and tube wall outer layer
Glass fiber PE prepreg tape cross-helicity is wrapped in enhancement layer made of tube wall internal layer surface, and enhancement layer cross winding is in tube wall internal layer
Outer surface, and be integrally formed with tube wall internal layer, the fusion of tube wall outer layer.The utility model obtains compound by using above-mentioned technology
Pipe, novel in design, structurally reasonable, the shortcomings that overcoming both metal tube and steel-plastics composite pipe, using continuous glass-fiber PE prepreg tape
The problem of cross winding is integrated as middle reinforcement layer, three layers of fusion, and production technology is controllable, and interfacial separation is not present, and it is resistance to
Compressive Strength is high, cost is also greatly lowered, and has very high cost performance.CN201310705553 continuous fiber reinforcement polyolefin is multiple
It closes pipe and its preparation process patent is related to a kind of continuous fiber reinforcement polyolefin multiple tube and its preparation process, including internal layer modeling
Interior hot melt adhesive layer is arranged outside, continuous fiber impregnated tape is arranged outside interior hot melt adhesive layer for expects pipe, the inner layer plastic tube, and continuous fiber soaks
External hot melting glue-line is set outside stain band, outer layer plastic tube is set outside external hot melting glue-line, which effectively increases the resistance to of composite pipe
Compressive Strength, multiple tube crushed material can directly have longer glass with recycling and reusing, simple process and low cost, and in crushed material
Fibre is used as reinforcing material, which can be used as high-intensitive enhancing modified materials and use.
It is enhancing that sum up all patents, which are all not involved with high pressure and large-diameter pipeline after being satisfied with circumferential pressure,
Axial stress and the Strengthening Design made.
With the pipe-line system of pressure, the more big corresponding axial tension stress of its bigger basal area of caliber increases at geometry grade；Together
Its basal area of the pipe-line system of caliber is identical, but increases exponentially as pressure increases exponentially its axial tension stress.
The continuous fiber reinforced plastic compound pipeline complex pipeline sold in the market is twined with circumferential unidirectional prepreg tape hot melt
Requirement of 2.0MPaDN500mm or less the pipe-line system to axial tensile stress is satisfied with around pipeline sandwich layer.
