Description
Technical field
The present invention relates to composite production technical field, be specifically related to the making molding side of a kind of composite material pipe
Method.
Background technology
In recent years, carbon fiber pipe market development is rapid, is widely used in fields such as automobile, Aero-Space, buildings.China
Composite material tube market development is the rapidest, product output continuous expansion, and national industrial policies encourage composite material tube industry
Developing to high-tech product direction, domestic enterprise's newly-increased investment project investment gradually increases.Investor is to composite material tube market
Concern increasingly closer, this makes composite material tube market increasingly be paid close attention to by each side.Therefore, such as minimum one-tenth
It is high that basis, simplest method produce intensity, and the tubing of good rigidity becomes an extremely important problem.
Composite material tube manufacture method mostly is in the market:
1, winding method: this method molding needs wrapping machine, core, solidifying heating furnice, ingot stripper and masterful technique work
People, the method is applied to large-sized workshop, and the investment of needs is relatively big, relatively costly.
2, silicone rubber method: its manufacture method is with silicone rubber as core, is wound around fiber cloth (fiber prepreg at silastic surface
Material), utilize the principle that silicone rubber expands with heat and contract with cold, during heating, silicone rubber expands, and reaches the size of tubing requirement, lowers the temperature cold after solidification
But, silicone rubber shrinkage, become original size, it is simple to the demoulding.Silicone rubber is only 2-3 time service life, so method is relatively costly.
3, air bag method: its manufacture method is using air bag as core, and fiber reinforced plastic mold is external mold, and wherein air bag is only
For inner support effect.Owing to filling with air inside air bag, therefore core is softer, tubing inside dimension inaccuracy, product
Can be relatively low.
Summary of the invention
The shortcoming of prior art in view of the above, it is an object of the invention to provide the making of a kind of composite material pipe
Forming method, in order to improve the problem such as tubing high cost, low-intensity present in prior art.
To achieve these goals or other purposes, the present invention is achieved by the following technical solutions:
The making forming method of a kind of composite material pipe, comprises the steps:
(1) air bag is entirely pneumatic, standby；
(2) air bag after step (1) being inflated is internal fills iron ore, as core；
(3) mandrel surface in step (2) pastes politef mould, smears hole sealing agent, then smear after stickup
Releasing agent；
(4) mandrel surface obtained in step (3) is wound around carbon fiber prepreg, is then around release cloth, heat shrink films；
(5) baking oven elevated cure: put in baking oven by the product that step (4) obtains, be warming up to 95-100 DEG C, is incubated 30-
35min, then proceedes to be warming up to 125-130 DEG C, is incubated 30-35min；
(6) demoulding: after insulation terminates in step (5), after baking oven naturally cools to room temperature, product is taken out, by thermal contraction
Film, release cloth remove, and are poured out by iron ore, air bag and poly tetrafluoroethylene are removed, obtain composite material pipe.
Further, the diameter after described inflatable bag inflating is identical with pipe diameter.
Further, described air bag can heatproof more than 150 DEG C.
Further, a diameter of 0.2-0.3mm of described iron ore.Further, a diameter of 0.2mm of described iron ore.
Further, the hole sealing agent used in step (3) is that Zyvax Sealer AC (has than international trade purchased from an angstrom method
Limit company).
Further, it is 1-4 time that described hole sealing agent smears number of times, and each interval time is 20min.When mould uses for the first time
Time, the number of times of smearing of hole sealing agent is 4 times, and each interval time is 20min；When mould is not to use for the first time, hole sealing agent is smeared
Number of times only needs once.
Further, the releasing agent used in step (3) is that FLEX-Z-5.0 releasing agent (has than international trade purchased from an angstrom method
Limit company), one in Frekote-55NC releasing agent (purchased from Henkel-Le Tai).
Further, the number of times of smearing of described releasing agent is 2-6 time, and each interval time is 20min.When mould makes for the first time
Number of times of smearing be 6 times, each interval time is 20min, only need to smear twice when reusing, and time interval is 20min.
Further, the carbon fiber prepreg used in step (4) is available from Jiangsu Tian Niao new and high technology company limited, carbon
The 3k plain weave carbon fiber prepreg that fiber content is 59%, glue content is 41%, and carbon fiber content be 60%, glue content be
The 150g unidirectional carbon prepreg of 40%.
Wherein, in the present invention, carbon fiber prepreg is the composite semi-finished products that resin is manufactured with carbon fiber, is generally divided into
Two kinds of forms of dry and wet make, and carbon fiber prepreg used in the present invention is that wet method makes.
Further, step (4) core mould surface wrap two-layer carbon fiber prepreg, wherein top layer uses 3k plain weave carbon
Fiber prepreg material, is 0 ° of winding；Internal layer use 150g unidirectional carbon prepreg, by 0 °/90 °/45 °/-45 °/-45 °/
45 °/90 °/0 ° mode carries out symmetric layups.
Further, in the present invention release cloth can heatproof more than 150 DEG C, the acting as of release cloth facilitates composite product
The demoulding, i.e. realizes goods and separates with mould.
Further, heat shrink films of the present invention is the transparent film material of PVC thermal contraction, can heatproof 150 DEG C with
On, provide external pressure for production, it is achieved ensure the effect of product thickness.
Further, in step (5), the speed of twice intensification is 3 DEG C/min.
Further, during step of the present invention (6) demoulding, poly tetrafluoroethylene is not required to remove from air bag, convenient circulation
Use.
More than Zong He, the making forming method of the composite material pipe of the present invention, use iron ore to be filled in air bag, energy
The effective rigidity ensureing core, because the mobility of iron ore is easy to the demoulding during demoulding.Utilize poly tetrafluoroethylene, it is ensured that
The aesthetic property of tube surfaces and stripping result.Use heat shrink films, it is ensured that product surface uniform-compression, structural behaviour is strong.
Method provided by the present invention without shorter mould in the service lifes such as silicone rubber, but use blowing bag, iron ore,
Poly tetrafluoroethylene, heat shrink films etc., can effectively reduce cost, improves work efficiency；And gained tubing strength and stiffness are equal
Higher.
