Description
The application is Application No.：201610333315.7, the applying date：2016-05-19, " one kind has bubble to patent name
The divisional application of the patent of invention of the double-deck carbon fiber pipe and its manufacture craft of foam interlayer ".
Technical field
The present invention relates to carbon fiber field, and in particular to a kind of making work of the double-deck carbon fiber pipe with foam layer
Skill.
Background technology
Carbon fibre composite is progressively popularized from high-end fields such as Aero-Space to civil area, and carbon fiber pipe has
Proportion is small, rigidity is big, intensity is high, it is corrosion-resistant the advantages of, be widely used in medicine equipment, sports equipment.But it is due to its own
Characteristic makes the mechanical connection of carbon fiber pipe extremely difficult, so then being become using glue bonding, one kind is fairly simple efficiently to be connected
Connect mode.Nowadays, many steel construction pieces on automobile just gradually mitigate weight using the replacement of carbon fiber product.
The vehicle frame of truss-like automobile is formed by connecting by multiple tubing element, and traditional truss frame materials are mainly steel pipe or aluminium
Compo pipe, now new truss vehicle frame uses carbon fiber pipe, but is due to the connection between carbon fiber pipe and carbon fiber pipe
Connection with other parts can not use welding, can only be using bonding or bolt connection, but the intensity of bonding is smaller, and bolt
Connection can then destroy the carbon filament of carbon fiber pipe, make easily to be broken during its stress, for these situations, be used in the prior art
The carbon fiber pipe of truss vehicle frame is all to be bonded a metal joint at the two ends of carbon fiber body, then passes through metal joint and other
Carbon fiber pipe or part are attached.
Prior art is all first to make carbon fiber pipe, then coats glue on metal joint, then by carbon fiber pipe and
Metal joint sticks together, and fabrication cycle is long.Connect for convenience, fit-up gap be often set between carbon fiber pipe and joint,
The axiality so resulted between carbon fiber pipe and joint is bigger than normal, and glue is in uneven thickness, if coating adhesive dilutional hyponatremia
Words, unnecessary glue can also flow to joint be used for connect internal thread at, and joint and carbon fiber pipe end face, glue curing
After be very difficult to processing, cause post processing workload increase.When carbon fiber layer is Nian Jie with glue, joint modes of emplacement is usually
Horizontal positioned or vertical placement, due to the influence of gravity, glue federation skewness causes carbon fiber pipe Nian Jie with joint
Quality Down afterwards.
Existing carbon fiber pipe is all individual layer, because the thickness of carbon cloth is smaller, therefore carbon fiber pipe often wall thickness
It is smaller, its noise to automobile and vibrate no attenuation so that the noise of truss-like automobile and vibrate larger.Carbon cloth
The area Nian Jie with joint is also smaller, and in order to improve adhesive strength, generally requires the boss lengthening of joint, with increase its with
The area of carbon cloth contact, but so again the weight of carbon fiber pipe can be caused to increase.

Outer layer (91) is removed from external mold (9)；
Described outer layer carbon fiber pipe forming step is：To remove the external molds (9) of the first outer layer (91) again with metal joint
(4) connect, carbon cloth is wound on froth bed (2), the lateral surface of the second dome platform (61), to the metal joint (4) of one end
On the first permeability hole (53) in pour into the first permeability hole (53) on epoxy resin, the metal joint (4) of the other end by true
Blank pipe is connected with knockout drum, vavuum pump successively；The region that shell (90), internal model (8), the first sealing ring (53) are surrounded is vacuumized
And pressurize is for a period of time, the carbon cloth being wrapped on froth bed (2) and first dome platform (51) lateral surface is set to be cured as outer layer
Carbon fiber pipe (1).
2. a kind of manufacture craft of double-deck carbon fiber pipe with foam layer according to claim 1, it is characterised in that：
In described carbon fiber pipe forming step, epoxy resin is poured into the 3rd permeability hole (73) on the metal joint (4) of one end
And in the solidification process of internal layer carbon fiber pipe (3), described internal layer carbon fiber pipe (3) at the uniform velocity rotates around its axis all the time；To
The solidification process of foam, coagulator and froth bed (2) is poured into the second permeability hole (63) on the metal joint (4) of one end
In, described froth bed (2) at the uniform velocity rotates around its axis all the time；The first permeability hole (53) on the metal joint (4) of one end
In pour into the solidification process of epoxy resin and outer layer carbon fiber pipe (1), described outer layer carbon fiber pipe (1) is all the time around its axle
Line at the uniform velocity rotates.
