Description
Technical field
What the present invention relates to is a kind of matrix material and preparation thereof of carbon fibre material technical field, specifically is a kind of three-dimensional orthogonal carbon fiber reinforced aluminum matrix composite and preparation method thereof.
Background technology
Carbon fiber reinforced aluminum matrix composite approaches zero thermal expansivity and good dimensional stability in addition when having high specific strength, be successfully applied to man-made satellite support, man-made satellite parabolic antenna, space telescope etc.But unidirectional carbon fiber dimension reinforced aluminum matrix composites is adopted in above application more.The check configuration matrix material has anisotropic shortcoming, and the laminate structures matrix material also exists easy layering, along the rigidity of thickness direction with deficiency such as intensity is low, impelling strength and low, the anti-inplane shear intensity of damage tolerance are low.The matrix material of said structure exists above structure and performance deficiency, can not satisfy the multidirectional stressed request for utilization of high-strength light structured material.In addition, the prefabricated carbon fiber spare of unidirectional and laminate structures is in the process of preparation matrix material, and the easy generation of thomel gathers and buckling phenomenon partially, thereby causes the integral material mechanical properties decrease.And three-dimensional orthogonal prefabricated carbon fiber spare is the general frame structure, has very high rigidity, in the process of preparation matrix material, takes place to gather partially and crooked problem thereby overcome thomel.
Retrieval through to prior art is found; One Chinese patent application numbers 200910249794 in open day on May 26th, 2010, has been put down in writing a kind of " metal matrix three-dimensional netlike carbon fiber composite material and method of manufacture thereof "; This technology constitutes the three-dimensional netlike carbon fiber structure by multilayer carbon nanotube; But this prior art for preparing complex process at first needs formulated suspension, passes through technologies such as drying treatment, compressed moulding, setting treatment, high temperature sintering and composite molding again.Thomel skewness in the prefab of suspension settlement method preparation, fiber volume fraction is distribution gradient on thickness direction.In addition, sticker and the dispersion agent introduced during formulated suspension have disadvantageous effect to the composite material interface performance.
Summary of the invention
The present invention is directed to the above-mentioned deficiency that prior art exists; A kind of three-dimensional orthogonal carbon fiber reinforced aluminum matrix composite and preparation method thereof is provided; Adopt the three-dimensional orthogonal thomel to strengthen body, the method through extrusion casting obtains a kind of three-dimensional orthogonal carbon fiber reinforced aluminum matrix composite, and wherein fibrous bundle runs through three directions of X, Y, Z of material; Fibrous bundle does not interweave each other, has fundamentally solved the defective of existing continuous carbon fibre reinforced aluminum matrix composites on structure and performance.Adopt weaving directly to prepare the three-dimensional orthogonal carbon fiber structure; There are not formulated suspension and subsequent drying processing, compressed moulding, setting treatment, high-sintering process; Thereby simplify preparation technology greatly, shorten preparation time; Avoided the problem of fiber volume fraction distribution gradient on thickness direction, sticker of having introduced when also having avoided formulated suspension and dispersion agent are to the disadvantageous effect of composite material interface performance.Because the fiber volume fraction of three-dimensional orthogonal carbon fiber structure is higher, so liquid metal is bigger to the filling difficulty of prefab.To the three-dimensional orthogonal constructional feature of prefabricated carbon fiber spare,, realized the compound of three-dimensional orthogonal thomel and aluminum or aluminum alloy through choosing suitable Squeeze Casting Parameters on Microstructure.Meanwhile, the general frame structure of high rigidity has overcome thomel and in the process of preparation matrix material, takes place to gather partially and crooked problem.
The present invention realizes through following technical scheme:
The present invention relates to a kind of three-dimensional orthogonal carbon fiber reinforced aluminum matrix composite; Its component and volume ratio are that 30～60% thomels strengthen body and 40～70% aluminum or aluminum alloy matrixes are formed; Wherein: the component of aluminum or aluminum alloy matrix and mass percent are: 0～13%Si, 0～11%Mg, 0～10%Zn, 0～8%Cu, 0～2%Mn, 0～1%Ti, all the other are Al.
The present invention relates to the preparation method of above-mentioned three-dimensional orthogonal carbon fiber reinforced aluminum matrix composite, utilize woven working method that carbon fiber bundle is made into three-dimension integrally reticulated structure body, and place the metal die preheating; Then fused aluminum or aluminum alloy melt cast is gone in the metal die,, obtain the three-dimensional orthogonal carbon fiber reinforced aluminum matrix composite at forming under the pressure.
The temperature of described preheating is 400 ℃～600 ℃.
