The invention improves the shearing strength and, which reduces cost.
Description
Technical field
The present invention relates to a kind of preparation method of self-reinforced interlayer shearing intensity resin base fiber reinforced composite material.
Background technology
Advanced polymer matrix composites with its outstanding lightweight, high heat-resisting, height ratio strong, the characteristics of height ratio mould and playing the part of indispensable key player in modern industry, the research and development level of composite has been considered to estimate the important indicator of a national comprehensive strength.The performance that material is higher, better manufacturability, suitable cost are the targets that people pursue always.Yet general, the interlayer shear performance of composite is lower, and impact is very sensitive, especially when suffering low velocity impact.And be the advanced composite material of representative with the carbon fiber, this problem is more outstanding, seriously restricts it than the more application under the exacting terms of work on hand environment.
The method of the interlaminar shear strength of raising composite is more, roughly can consider, promptly obtain the composite of high interlaminar shear strength by the interfacial adhesion strength between the body intensity, fiber and the matrix that improve polymer, the structure (as two dimension, 3 D weaving etc.) of rationalization's fibre reinforcement from resin matrix, fortifying fibre, three aspects, interface.These methods are all comparatively effective and obtained application, but also have certain problem, can make the bigger potentiality of existing resin system performance as braiding structure, still be method itself no matter from resin system, all help reducing cost, still, this method is difficult to be used in labyrinth.In addition, braiding structure causes the bending of fiber inevitably, thereby reduces the mechanical property of composite.Moreover the cost of braiding is higher.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of self-reinforced interlayer shearing intensity resin base fiber reinforced composite material.
The technical solution adopted for the present invention to solve the technical problems is: the step of this method is as follows:
1) liquid crystal hot solids weight resin percentage composition is 5～100% in the matrix resin, and the aathermoset resin system weight percentage is 95～0%;
2) prepare the fiber prepreg by wet method or fusion method; Or adopt liquid phase moulding process forming composite, then need not prepare prepreg;
3) with prepreg overlay, put into mould, composite material forming method forming composite routinely, in forming process, apply magnetostatic field or variable pulse magnetic field that magnetic field intensity is 2-20T simultaneously, the liquid crystal hot solids is orientated at direction initialization, after mold pressing finishes, naturally cool to normal temperature after, mould unloading promptly gets the self-reinforced interlayer shearing intensity polymer matrix composites; Or carry out post processing again, naturally cool to normal temperature after, mould unloading promptly gets the advanced polymer matrix composites of self-reinforced interlayer shearing intensity.
Described liquid crystal hot solids resin system is a kind of and any combination in epoxy resin by using liquid crystal system, liquid crystal bismaleimide resin system, liquid crystalline acrylate ester resin system or the liquid crystal unsaturated polyester resin system.
Described aathermoset resin system is a kind of and any combination in epoxy-resin systems, bismaleimide resin system, unsaturated polyester resin system, properties of diallyl isophathalate resin, cyanate ester resin system or the phenolic resin system.
Described liquid phase moulding process is meant resin transfer moulding and resin infiltration process.
Described conventional forming composite method is compression molding, laminated into type, autoclave moulding, vacuum bag is molded, contact is molded or long filament is Wrapping formed.
The present invention compares the beneficial effect that has with background technology: the present invention is a matrix with the resin that contains the aligned liquid-crystal hot solids, utilizing electromagnetic field effect is liquid crystal molecular orientation, thereby improve the fracture strength of material by the development that molecularly oriented effectively hinders crazing, obtain self-reinforced material.Secondly, effectively reduce thermal coefficient of expansion (CTE), it is poor because of CTE differs the shrinkage stress difference and the interfacial stress that cause too greatly to reduce matrix and interlaminar resin.The 3rd, make the differently-oriented directivity of mesomorphic unit and the radially quadrature of fiber, forming " pinning " effect makes the contact between fiber and the resin matrix become the three-dimensional connection with three-dimensional effect from original simple bonding interface (two dimension), thereby increase substantially the interlaminar shear strength of goods, effectively solve the interlayer cracking problem that is prone to after the laminar composite goods are hit.
