Description
Technical field
The present invention relates to the modification of composite material and interlayer toughened technology, specially a kind of screw type composite material toughening is thin
The forming method of stick, this method is mainly used for improving the interface performance between the thin stick of composite material toughening and laminate, to mention
The interlaminal toughness of high laminated composite.
Background technique
Conventional two-dimensional laminated composite has mechanical performance in good face, but does not have fiber reinforcement between its each layer,
Only play a part of bonding and transmitting load by matrix resin, therefore perpendicular to the performance phase between laying direction and laying
To weaker.When being acted on by external load, which often generates interlaminar failure, while composite layer first
Between the lower damage-resistant for also resulting in composite material of intensity can be poor.In order to improve these disadvantages of laminated composite, out
Many technologies for improving composite material interlayer toughness are showed.Thin stick toughening technology is cured in the thickness direction insertion of prepreg
The thin stick of composite material, to be provided overseas Chinese federation's power of thickness direction by toughening material.This method is since cost is relatively low, to material
Performance influences smaller in face, and toughening effect is obvious, the extensive concern by academia and industry.
The transmitting of load is realized by interface between the thin stick of toughening and laminate.And scientific research is used and industrial toughening is thin
Stick is the more smooth cylindrical structure in surface, if be modified to thin stick surface or to thin stick state improve thin stick with it is laminated
Interface performance between plate then can be further improved thin stick to the toughening effect of laminate.Composite material surface modification technology
Have very much, including the coarse modification of physics, chemical etching, coating etc..However, the diameter of section of the thin stick of composite material toughening generally exists
1mm is hereinafter, composite product for this fineness, the coarse modification of traditional physics are easy to cause to damage to material, engineering
There are difficulty in realization.Since the resin of the thin stick of toughening is usually that epoxy resin or span carry out phthalimide resin, both resins
There is excellent corrosion resistance, according to the method for chemical etching, effect is not obvious after solidification.In addition, carrying out table to thin stick
Finishing coat, toughening effect be not also significant.
Summary of the invention
In view of the above-mentioned problems, it is an object of that present invention to provide a kind of forming method of thin stick of screw type composite material toughening,
This method changes the section morphology of traditional slim rod, make the thin stick of composite material toughening have helical structure, using the thin stick into
When the interlayer toughened of row product, helical structure will generate packing interaction, can greatly improve the boundary between thin stick and laminate
The interlayer toughened of face performance and product.And this method only adds a twining steps in the thin stick production process of toughening, and it is right
The production efficiency of thin stick is almost no impact, and any subsequent independent process is not present, high-efficient, at low cost.
In order to achieve the above objectives, the present invention discloses a kind of forming method of thin stick of screw type composite material toughening: firstly, will
2~4 strands containing identical orientation infiltrate resin containing fibre bundle (twist is between 0.5~8 twirl/cm) is twisted respectively；Secondly, wearing respectively
Molding die independent is crossed, molding die has circular cross-section through-hole type chamber, and pore size is designed as fibre bundle in type chamber
Interior volume content is 25%~70%；Third twists all fibres Shu Jinhang spiral for passing through mold, realizes plying,
In, orientation is contrary with single-stranded fiber beam, and the twist is between 0.2~5 twirl/cm；4th, the helical form that twisting is completed is closed
Stock fibre bundle makes the resin solidification of infiltration by hot environment；Finally, obtaining the thin stick of screw type composite material toughening.
In the forming method, the fiber can be carbon fiber, glass fibre, aramid fiber, basalt fibre etc.
High-performance fiber.
In the forming method, the resin can be epoxy resin, phenolic resin, unsaturated polyester (UP), vinyl esters,
The thermosetting resins such as bismaleimide (BMI), polyimide resin.
In the forming method, the orientation of the finally obtained thin stick of screw type toughening is with sub-thread containing the orientation phase for twisting fibre bundle
Instead.This is because after each single-stranded fiber beam with identical orientation gathers together, the effect meeting nature obvolvent of internal stress, shape
At the twisted fiber beam with opposite orientation.In thin stick forming process, each single-stranded fiber beam, which is gathered after conjunction is twisted, to be kept naturally
Screw type combines state.
Compared with prior art, this technology has the advantage that
Firstly, the thin stick surface of screw type composite material toughening of this method production will generate spiral type groove, and it is laminated
Chimeric effect can be played between plate, to improve the interlayer toughened effect of product.Secondly, this method is in production composite wood
Expect what the process kind of the thin stick of toughening was realized, only the step of need to adding a twisting, easily realizes and automate, is at low cost, high-efficient.
