Skill.
Background technique
In recent years, the research work of a large amount of aircaft configurations, which is all put forth effort on advanced composite material to manufacture, bears big load
Main force support structure, such as commercial and military aircraft wing, fuselage and empennage component, people are by thermosetting property and thermoplasticity
Matrix is in the machines such as subsonic speed transporter, advanced tactical fighter and the supersonic speed in future/hypersonic transporter.Aluminium closes
Gold is always the main material of aircraft and space shuttle structure, and the performance of present conventional aluminum alloys can no longer meet aircaft configuration
The requirement of weight and rigidity.Test result is it has been proved that composite structure can fully meet the requirement of aircaft configuration.
Summary of the invention
Expensive in order to overcome existing metal joint processing difficulties, the deficiency of quality weight, the present invention provides a kind of weight
Gently, intensity is high, rigidity is good, endurance, erosion-resisting composite joint structure.It by scientific design, rationally manufactures, sufficiently sends out
It waves that high-module high-strength carbon fiber specific strength is high, specific modulus is big, endurance, erosion-resisting advantage, and then obtains the ears of superior performance
Connector.
The technical scheme adopted by the invention is that: full carbon fiber ears connector, including be made of high-module high-strength carbon fiber
Bottom surface laying, the double layings of vertical auricle list laying and vertical auricle, vertical auricle list laying and the double layings difference of vertical auricle
It is arranged perpendicular to horizontal laying, the ratio of 0 °, 45 °, 90 ° laying of above-mentioned laying is 25:50:25.
Further, carbon fiber is separately filled between vertical auricle list laying and the double layings of vertical auricle and horizontal laying
One-way tape.
Further, the ratio of the laying of the double layings of horizontal bottom laying, vertical auricle list laying and vertical auricle is
50%。
Further, ears joint thickness is 6mm, part thickness 6.5mm, with vertical auricle list laying and the double pavings of resin auricle
The joint face of layer is the laminate structure of V-structure.
Pass through the integral ears connector of autoclave molding legal system, and the combination die in autoclave using composable mold
Tool gives ears connector product to apply pressure in the movement of autoclave interior orientation, is then pressed into ears connector using vacuum bag.
Further, composable mold includes left mold, intermediate mold and right mould tool, and these three molds are successively set respectively
In the leftward position of the ears of ears connector, middle position and right positions.
Compared with prior art, the beneficial effects of the present invention are: full carbon fiber ears connector produced by the present invention, sufficiently sends out
Wave that high-module high-strength carbon fibre composite specific strength is high, specific modulus is big, endurance, erosion-resisting advantage, and then it is excellent to obtain performance
Ears connector more, can make jointing loss of weight 15% ~ 25% on the basis of original hardware, while the invention can be with
It promotes the use of on other kinds of connector.
Detailed description of the invention
Fig. 1 is the ply angles schematic diagram of full carbon fiber ears connector；
Fig. 2 is the three-dimensional figure of the embodiment of Fig. 1；
Fig. 3 is the annexation figure of the ears connector and the mold for manufacturing it of the embodiment of Fig. 1；
Wherein: the bottom surface 1- laying, the vertical auricle list laying of 2-, the double layings of the vertical auricle of 3-, 4- carbon fiber one-way band, 5-V
The laminate structure of type structure, the left mold of 6-, 7- intermediate mold, 8- right mould tool.
Specific embodiment
In order to deepen the understanding of the present invention, present invention will be further explained below with reference to the attached drawings and examples, the implementation
Example for explaining only the invention, does not constitute protection scope of the present invention and limits.
As depicted in figs. 1 and 2, full carbon fiber ears connector, including using bottom surface laying made of high-module high-strength carbon fiber
1, vertical auricle list laying 2 and the double layings 3 of vertical auricle, vertical auricle list laying 2 and the double layings 3 of vertical auricle are respectively perpendicular to
Bottom surface laying 1 is arranged, and the ratio of 0 °, 45 °, 90 ° laying of above-mentioned laying is 25:50:25.
In the above-described embodiments, it is filled out respectively between vertical auricle list laying 2 and the double layings 3 of vertical auricle and horizontal laying 1
Filled with carbon fiber one-way band 4.The ratio of the laying of horizontal bottom laying 1, vertical auricle list laying 2 and the double layings 3 of vertical auricle
Be 50%, the ears connector being prepared under shape unanimous circumstances, using only original ears joint thickness one third extremely
The thickness of a quarter can reach intensity and rigidity as existing ears connector, while largely mitigate
The weight of ears connectors.
When ears joint thickness is 6mm, part thickness 6.5mm, the company with vertical auricle list laying and resin auricle pair layings
Junction is the laminate structure 5 of V-structure, and ears connector obtained has higher intensity and bending rigidity, and its weight
Only existing 15-18%.
Pass through the integral ears connector of autoclave molding legal system, and the combination die in autoclave using composable mold
