Description
Technical field
The present invention relates to a kind of carbon fibre composites, more particularly to one kind is for weaving microscopical structure carbon fiber composite
The three-dimensional framework of material.
Background technique
Currently, 3 D weaving carbon fiber composite material is steady by its superpower toughness, energy absorption, lightweight flexible, structure
The characteristics such as fixed, corrosion-resistant and high temperature resistant, have been widely used in the fields such as aerospace, high-end industry, but in practical application
In, especially in use condition more harsh environment, existing carbon carbon composite is had the following deficiencies:
First, existing most of carbon carbon composite skeletons are first is that the Nomex made of nonwoven acupuncture technique, this method
The big tow precursor with polyacrylonitrile (PAN), through pre-oxidizing tow made of pre-oxidation process equipment, through subsequent stretch break method or
The process of chopping becomes pre-oxidation staple fiber (not being carbon fiber).Then pre- oxygen staple fiber is passed through into nonwoven acupuncture process equipment process,
The pre- oxygen Nomex of limited thickness is made, becomes framework material.Because being limited by needling process condition, Nomex is soft, close
It spends lower in 0.26g/cm3Left and right, and preoxidized fiber intensity is poor.Second is that two dimension (the warp, latitude) planar cloth being made by carbon fiber,
Or by carbon-fibre nonwoven prepreg cloth (piece), in in-plane between layers with 0 °/90 ° angles or other angles laying, and
Short carbon fiber is filled therebetween, its density is increased with this, is overlapped into required thickness, then in vertical direction (Z-direction), then by carbon fiber
Dimension long filament is continuous through the three-dimensional framework material that suture (the similar method for pricking sole by hand) is constituted, and density is in 0.3~0.4g/
cm3.So carbon fiber skeletal density is not high, after subsequent vapor deposition or liquid impregnation high temperature enhancing processing intensity it is not high,
Especially needling process method, the more aobvious intensity of preoxidized fiber used is insufficient.
Second, the skeleton made of Nomex, because of restriction of the length by steel needle length of material and rigidity of Nomex, needle
The thickness of thorn felt is usually no more than 50 millimeters, to obtain required thickness, to be then superimposed in layer with adhesives, thickness
500 millimeters (50 millimeters x10 layers), therefore easily delamination strength is poor.And the skeleton made of the method for layer paving, because being grown by elongated acupuncture treatment
The restriction of degree and rigidity, such skeleton are no more than 360 millimeters in length direction maximum.So both methods can not all be made
The carbon fibre composite skeleton of large volume.
Third, the carbon fibre composite skeleton made of the method for Nomex or layer paving, skeletal internal path is chaotic,
It is easy to produce resistance, causes to penetrate into not deeply, and the gas of skeletal internal is not easy to be discharged, thus manufactured composite inner meeting
Gas bag is formed, is not easy to be discharged, when encountering high temperature and pressure, the destruction of product can be brought.
Fourth, the carbon fibre composite skeleton made of the method for Nomex or layer paving, can only use single original
Material is of limited application, and cannot improve performance by the way of shuffling according to special application characteristic.
Therefore, for the problems of above-mentioned prior art, on those skilled in the art urgently develop and can overcome
State the carbon fiber rod skeleton structure of disadvantage.
Summary of the invention
Present invention aim to address carbon fibre composite institute is made with the method that Nomex or layer are spread in the prior art
The existing above problem, provides that a kind of stabilized structure, uniform force, anti-impact force are strong, the thin for weaving of large volume can be made
See the three-dimensional framework of structural carbon fiber composite material.
To achieve the above object, the invention adopts the following technical scheme:
The present invention provides a kind of for weaving the three-dimensional framework of microscopical structure carbon fibre composite, including one group laterally sets
