Description
Technical field
The invention belongs to composite Z-pin (i.e. Z-direction strengthens) technical field, more particularly to a kind of composite Z-direction increases
Strong ultrasound method for implantation.
Background technology
Most advanced composite material is formed by prepreg laying solidify afterwards, for answering for being prepared from by prepreg
Condensation material laminate, its interlayer performance is weaker, and the impact to foreign object is quite sensitive, under the impact compared with low energy object,
Also such as fibrous fracture, MATRIX CRACKING, layering equivalent damage can be caused in laminate, under causing its mechanical property by a relatively large margin
Drop.Interlayer performance deficiency is the greatest weakness of composite laminated plate, improves the method for interlayer performance and can substantially be divided into two classes：
(1) the materialogy method of laminate interlaminal toughness is improved by improving component material performance；(2) introduce and increase in a thickness direction
The construction design method of strong fiber, such as Z-pin technologies, 3 D weaving, suturing skill.
Composite laminated plate is easily layered, and delamination damage can be produced to structural strength and had a strong impact on, and layering interfaces are due to answering
Power, which is concentrated, to be more prone to crack.In the technology for improving interlaminal toughness, for other manner, Z-pin enhancing technology tools
There is production cost low, production prepares simple, the advantages of processing quality is easy to control.Z-pin presence can significantly improve lamination
The interlaminar strength and separation resistance of plate, while local strengthening can be carried out to part-structure.
Document " number of patent application is 201310694677.5 Chinese invention patent " discloses a kind of containing Z-pin reinforcings
Fibre preforms manufacturing method, this method prepares the foam preform containing Z-pin first, and will prepare the foam preform finished
Fiber preform surface to be fortified is positioned over, is then directly pressed the Z-pin in foam preform using ultrasonic implanted device
Enter in the fiber preform.It can make Z-pin is implanted into fiber preform in this way in theory and carry out longitudinal strengthening.
But in practice, because the fiber in precast body interlocks fine and close distribution, and often diameter is smaller (generally for carbon fiber Z-pin components
The 0.1mm orders of magnitude), when the certain depth being implanted in precast body, the front end of carbon fiber Z-pin components is due to wearing and tearing just no longer
It is sharp keen, start to diverge, this causes implantation resistance to rise rapidly, starts simultaneously at and causes wider to the fiber in precast body
Destruction, when the preceding end resistance of carbon fiber Z-pin components increases to a certain degree, just can not continue implantation, if pass through increase
Carbon fiber Z-pin components are pressed into by the mode of external force by force, it is likely that cause laminate precast body combination property significantly under
Drop.
The composite laminated plate component thickness in the fields such as Aero-Space alreadys exceed 50mm, super using existing Z-pin
Sound method for implantation can not meet the resultant performance enhancements of this kind of large-thickness component.Consulting the feelings of a large amount of correlation technique datas
Under condition, find it is domestic at present also without it is a kind of be suitable for big thickness, it is difficult be implanted into, the composite laminated plate precast body of easy damaged
Interlayer reinforcement technique.Therefore, if can be on the basis of the ultrasonic method for implantation of existing Z-pin, introducing portion innovation surpasses Z-pin
Sound be implanted in meet big thickness laminate precast body efficiently implantation on the premise of, while the comprehensive of composite is substantially improved
Can, this large-scale application to composite in every field has great importance.
