Description
The application be application No. is: 201610333315.7, the applying date: 2016-05-19, patent name " one kind have bubble
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 fields, and in particular to a kind of production work of the double-deck carbon fiber pipe with foam layer
Skill.
Background technique
Carbon fibre composite is gradually universal to civil field from high-end fields such as aerospaces, and carbon fiber pipe has
The advantages that specific gravity is small, rigidity is big, intensity is high, corrosion-resistant is widely used in medical instrument, in sports equipment.But due to its own
Characteristic keeps 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 are just gradually replaced using carbon fiber product to mitigate weight.
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, novel truss vehicle frame uses carbon fiber pipe now, but due between carbon fiber pipe connection and carbon fiber pipe
Connection with other parts is not available welding, using bonding or can only be bolted, but the intensity being bonded is smaller, and bolt
Connection can then destroy the carbon filament of carbon fiber pipe, make to be easy to happen fracture when its stress, in view of 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 both ends of carbon fiber tube body, then pass through metal joint and other
Carbon fiber pipe or part are attached.
The prior art is all first to make carbon fiber pipe, then the coating glue on metal joint, then by carbon fiber pipe and
Metal joint sticks together, and fabrication cycle is long.In order to facilitate connection, fit-up gap is often set between carbon fiber pipe and connector,
Result in the concentricity between carbon fiber pipe and connector bigger than normal in this way, and glue is in uneven thickness, if coating glue is excessive
Words, extra glue can also flow to connector for connection internal screw thread at and connector and carbon fiber pipe end face, glue curing
After be very difficult to handle, cause post-processing workload increase.When carbon fiber layer is Nian Jie with glue, connector modes of emplacement is usually
Horizontal positioned or vertical placement, due to the influence of gravity, glue is always unevenly distributed, and causes carbon fiber pipe Nian Jie with connector
Quality decline afterwards.
Existing carbon fiber pipe is all single layer, since the thickness of carbon cloth is smaller, carbon fiber pipe often wall thickness
It is smaller, noise and the no attenuation of vibration to automobile, so that the noise of truss-like automobile and vibration are larger.Carbon cloth
The area Nian Jie with connector is also smaller, and in order to improve adhesive strength, generally requires to lengthen the boss of connector, with increase its with
The area of carbon cloth contact, but the weight that will lead to carbon fiber pipe again in this way increases.

The region that one outer layer (91), internal layer carbon fiber pipe (3), the second sealing ring (62) surround；Then it removes external mold (9), and by first
Outer layer (91) is removed from external mold (9)；
The outer layer carbon fiber pipe forming step are as follows: will remove the external molds (9) of the first outer layer (91) again with metal joint
(4) connect, froth bed (2), the second dome platform (61) lateral surface on wind carbon cloth, the metal joint (4) of Xiang Yiduan
On the first permeability hole (53) in pour into epoxy resin, the first permeability hole (53) on the metal joint (4) of the other end passes through true
Blank pipe is successively connect with knockout drum, vacuum pump；The region surrounded to shell (90), internal model (8), the first sealing ring (52) vacuumizes
And pressure maintaining is for a period of time, and the carbon cloth being wrapped on froth bed (2) and first dome platform (51) lateral surface is made 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 the carbon fiber pipe forming step, epoxy resin is poured into the third permeability hole (73) on the metal joint (4) of Xiang Yiduan
And in the solidification process of internal layer carbon fiber pipe (3), the internal layer carbon fiber pipe (3) is at the uniform velocity rotated around its axis always；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, the froth bed (2) is at the uniform velocity rotated around its axis always；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), the outer layer carbon fiber pipe (1) is always around its axis
Line at the uniform velocity rotates.
