Abstract
The invention discloses a molding method for a carbon fiber composite material pipe. The molding method comprises the following steps: step 1. impregnating carbon fibers and glass fibers into a resin base body to form prepreg; step 2. softening the prepreg by a hot roller on a pipe reeling machine; winding the prepreg on a core shaft according to the required thickness, and winding and tensioning the outer surface of the prepreg by using a thin film; step 3. putting the prepreg into a curing furnace, curing, and carrying out post-treatment on a cured and molded pipe; and step 4. winding the prepreg on the pipe according to a pre-set path and putting the prepreg into a baking oven, and pulling out the core shaft to be de-molded after the resin is hardened. The molding process is simple, the process controllability is strong and the quality of finished products is stable.
Description
Technical field:
The present invention relates to a kind of tubular object extruding technology, is specifically a kind of forming method of carbon fibre reinforced pipe.
Background technology:
Relative to ductile iron pipe and armored concrete pipe of cement, fiber composite pipe has apodeictic environment resistance, anticorrosion, and acid and alkali resistance and industrial atmosphere are functional, can not produce corrosion.The test of fiber composite pipe endurance can reach more than 1,000,000 times, from the mode of fatigue fracture, the fatigue fracture of general ductile iron pipe and armored concrete pipe of cement be all paroxysmal, there is no sign, and the fatigue fracture of fiber composite pipe is generally after there is crackle, objectively add the possibility of accident anticipation, thus improve the security of use.For damage, fiber composite pipe has good recoverability, long service life.When damage appears in ductile iron pipe and armored concrete pipe of cement, recoverability is little, repair or weld job difficulty large.But when damage appears in fiber composite pipe, only simply need repair damage location, just effectively can improve the service life of fiber composite pipe.Lightweight, the density of resin-based carbon fiber and glass fiber compound material is respectively 1.8g/ ㎝
3, 2.5g/ ㎝
3, far below the density of ductile iron pipe and armored concrete pipe of cement, be easy to carry and transport, greatly reducing cost of transportation.Intensity is strong, and rigidity is large.Its stretch modulus can reach more than 1.5 times of high-strength steel.The tensile strength of ductile iron pipe is: 550Mpa, and percentage elongation is 7%; The tensile strength of carbon fiber is: 4900Mpa, and percentage elongation is: 2.1%; The tensile strength of glass fibre is: 3497Mpa, and percentage elongation is: 4.6%.Anti-permeability performance is strong.The anti-permeability performance of ductile iron pipe does not have the anti-permeability performance of fiber composite pipe strong, and will increase wall thickness when armored concrete pipe of cement does small-bore pipe and could meet seepage resistance demand, and this is do not need to increase wall thickness just can reach seepage resistance demand for fiber composite pipe.
But the complex forming technology of existing carbon fibre reinforced pipe, the not high quality of finished that causes of process controllability is unstable, thus makes cost remain high.
Summary of the invention:
Technical problem to be solved by this invention is, provide a kind of moulding process simple, the forming method of the carbon fibre reinforced pipe that process controllability is strong, the method can significantly improve the end product quality of carbon fibre reinforced pipe, and production cost is low.
Technical solution of the present invention is, provide a kind of forming method of carbon fibre reinforced pipe, it comprises the following steps,
The first step, by carbon fiber with glass fiber impregnatedly form prepreg in resin matrix, the mass percent of carbon fiber and glass fibre is respectively 10-30% and 70-90%;
Second step, softens prepreg by the hot-rolling on rolling machine, makes the resin melting on prepreg, is wound on mandrel by prepreg by stack design structure, and is wound around tension in the outside of prepreg with film strip;
3rd step, takes off from rolling machine, puts into curing oven and solidify after cold roller cooling and shaping, and carries out end face equating, the post processing of cleaning dust to the tubing of curing molding;
4th step, is wrapped in prepreg on tubing by the path preset, then puts into baking box, by the central spindle abstraction demoulding after hardening of resin.
As preferably, the carbon fiber in the first step and the resin matrix of glass fibre are epoxy resin.
As preferably, the mass percent of carbon fiber and glass fibre is respectively carbon fiber 20%, glass fibre 80%.
Further, the film strip in second step is polypropylene film with.
The present invention has the following advantages compared to prior art: moulding process of the present invention is simple, and process controllability is good, can duplication of production, is applicable to producing in enormous quantities, reduce production cost, and automaticity is high, fiber continuity.
Detailed description of the invention:
Below in conjunction with detailed description of the invention, the invention will be further described:
Embodiment
A forming method for carbon fibre reinforced pipe, it comprises the following steps,
The first step, by carbon fiber with glass fiber impregnatedly form prepreg in resin matrix, the mass percent of carbon fiber and glass fibre is respectively 10-30% and 70-90%, adopts carbon fiber 20% in the present embodiment, glass fibre 80%, resin matrix is epoxy resin;
Second step, by the hot-rolling on rolling machine, prepreg is softened, make the resin melting on prepreg, under certain tension force effect, roller is in operation process, by the frictional force between roller and core, prepreg thickness is on request wound on mandrel, and is wound around tension in the outside of prepreg with polypropylene film band;
3rd step, takes off from rolling machine, puts into curing oven and solidify after cold roller cooling and shaping, and carries out end face equating, the post processing of cleaning dust to the tubing of curing molding; In this step in order to better clean dust, first can carry out demoulding process, namely mandrel being taken out and carrying out post processing again, again mandrel being put back to after post processing completes;
4th step, is wrapped on tubing by prepreg by the path preset, adopt miter angle, 0 degree of angle and an angle of 90 degrees to circulate successively in the present embodiment to be wound around ply angles, then put into baking box, by the central spindle abstraction demoulding after hardening of resin.
The carbon fiber of fibrous composite pipe employing 20% and the glass fibre processing of 80% roll bag and paste shaping, and effectively combine carbon fiber resistance to compression, hot strength is good, non-deformability is the highest, lightweight feature and glass fibre cost low, shock resistance is good, absorbs damping good, nonconducting feature.The ply angles that Lay up design uses miter angle, 0 degree of angle and an angle of 90 degrees to circulate successively respectively.Miter angle fiber, plays the effect of antifatigue, 0 degree of angle and an angle of 90 degrees fiber lay down layer method, then mainly increase its compression strength and the anti-interior intensity of pressure.
Below only just preferred embodiment of the present invention is described, but can not be interpreted as it is limitations on claims.
