Description
Technical field
The present invention relates to a kind of composite material/metallic stacked structure multiple tube co-curing manufacturing methods, are suitable for inner wall
Composite material/outer wall is the manufacturing process of the laminated construction multiple tube of metal material, belongs to technical field of composite material molding.
Background technology
In face of the light-weighted active demand of the pipe fittings such as mechanical drive shaft, partly using composite material or all using composite wood
The pipe fitting of material becomes the most important thing, and for extraordinary demand, inner wall is that material pipe is answered in the part that composite material/outer wall is metal material
Part comes into being.The classical production process of such part is frequently with composite pipe is cured, by surface size of polishing, with reference to
The pattern that the solidification by cement pattern of glued membrane combines composite pipe with metal tube.And realize composite material/metal
The key technology of laminated construction compound pipe molding is how composite material blank is placed in inner wall of metal tube, and is effectively bonded
On inner wall of metal tube and cure without generating fold.At present, in domestic and international generally use second bonding moulding process is realized
Wall is the manufacturing process that composite material/outer wall is metal material laminated construction multiple tube, but this process combining material pipe fitting is consolidated
The matching of outer diameter and metal internal diameter size after change can not ensure to be reached, it is necessary to carry out substantial amounts of machine to multiple material pipe
With the degree of cooperation of metal tube, and the system of lamination multiple tube need to could be completed by solidification process twice using above-mentioned technique
It makes, does not possess the co-curing moulding process cycle short advantages such as at low cost.
The content of the invention
In view of the deficienciess of the prior art, the technical issues of Zhi Xie Decision of the present invention is to propose a kind of composite material/gold
Belong to laminated construction multiple tube co-curing manufacturing method, it is compound which can complete laminated construction during one-step solidification
The manufacturing process of pipe realizes the fast and low-cost manufacture of product.
For achieving the above object, the present invention adopts the following technical scheme that complete：
Composite material/metallic stacked structure multiple tube co-curing manufacturing method, which is characterized in that comprise the following steps；
1）According to metal inner surface size and blank Lay up design, prepare steel pipe as blank laying mould, be bonded on frock surface
One layer of one-side band glue polytetrafluoroethylglass glass cloth, and successively two layers of tetrafluoro cloth of laying, one layer have hole isolation film, one layer of AIRPAD rubber
Glue and one layer of non-porous release film；
2）According to Lay up design, successively in frock surface laying prepreg, every 3 ~ 5 layers of vacuum debulk is not less than 30min, waits to presoak
In 2 layers of glued membrane of its surface laying and compaction treatment after material laying；
3）Using the lubricating effect between two layers of tetrafluoro cloth, the prepreg blank for having coated glued membrane is demoulded from laying frock, it will
Blank is placed in parallel in Clean room along tube axis direction and is encapsulated in case follow-up use；
4）Inner wall of metal tube is done into roughening treatment to increase the bonding force between composite material and metal, clear up metal fragment and
Respectively with acetone and absolute ethyl alcohol cleaning inner wall of metal tube after solid impurity；
5）The prepreg blank of outer surface package glued membrane is placed in the heating given not higher than resin and glued membrane below safe temperature
Heating is no more than 30min in equipment, and inner wall of metal tube is plunged into after blank state is slightly soft, with polyfluortetraethylene plate by blank
It is depressed into after being substantially bonded inner wall of metal tube, metal tube is by the pattern of material vacuum cylinder bag overturning encapsulation together with blank overall package
One vacuum passage, vacuumize makes blank be bonded inner wall of metal tube completely using negative pressure, and during subsequent one-step solidification
By glued membrane by metal tube with answering material pipe co-curing as entirety.
As a preferred embodiment, in step 2, it is necessary to when air-heater can be used giving safe temperature not higher than resin
Following local heating is to ensure glued membrane good fit prepreg.
Advantageous effect compared with prior art is：Composite material/metallic stacked structure multiple tube co-curing manufacturing method,
The process characteristic of auxiliary material is made full use of, blank not easy mold release is solved the problems, such as by specific laying order, and adopts
Packaging technology is overturn with vacuum cylinder bag, is pasted blank and inner wall of metal tube perfection using the negative pressure after encapsulation in vacuum bag system
It closes, and frock and product are encapsulated as whole pattern and make inside and outside compression balanced, and laminated construction is completed within the one-step solidification cycle
The same inch of multiple tube manufacture, the risk for effectively avoiding pressure differential that metal tube is caused to deform.
, there is not the problems such as fold, the subtle buckling of fiber in the laminated construction multiple tube manufactured using the moulding process
Degree does not influence product delivery, and compound by being bonded to composite material inner wall detail sanding or using cold curing adhesive
Material sheet calibrates the static balance of laminated construction multiple tube or dynamic balancing, you can reaches the lightweight purpose of pipe fitting.Really solution
Traditional dependence second bonding moulding process manufacture inner wall of having determined is that composite material/outer wall is that metal material laminated construction multiple tube is deposited
Curing after the matching of multiple material outer diameter and metal internal diameter size can not ensure the problems such as, avoid substantial amounts of follow-up machine
Add process and secondary curing process, be truly realized the fast and low-cost manufacture of composite material/metallic stacked structure multiple tube.
