Technical field
The present invention relates to the preparation technology of carbon cloth copper facing and metallic composite, belong to metallurgical technology field, relate in particular to a kind of preparation method of carbon cloth-Al alloy composite.
Background technology
Carbon cloth-Al alloy composite is composited by aluminium alloy with high specific strength and the carbon cloth with high ratio modulus, stretch-proof, has that density is low, specific strength is high, stretch-proof and a specific modulus advantages of higher.Its mechanical property can be carried out the adjustment in the certain limit through distribution and the control of al alloy component of adjustment carbon cloth in aluminium alloy.In fields such as building, military projects good prospects for application is arranged.
Use carbon cloth and metal material compound tense in the construction material of present stage, how it is pasted on the metal as the surface or as interlayer.Be characterized in that manufacturing procedure is simple and easy to control.But shortcoming is that this composite adhesion is very low, in use takes off easily and takes out, and is difficult to give play to carbon cloth stretch-proof and shear-stable advantage.
The specific strength of aluminium alloy Yin Qigao is usually used in the protection field.Present stage can be prepared short carbon fiber-Al alloy composite, but to improve its anti-shear ability effect significantly and arranging of carbon fiber be difficult to control.
Carbon cloth is being heated to meeting generation weightlessness more than 450 ℃, and this temperature can't reach the cast temperature of aluminium alloy; And because of it has hydrophobicity and surface inertness, moistening bad with metal bath, can't directly pass through casting method and aluminium alloy compound.
The present invention utilizes the method for electro-coppering after the carbon cloth preliminary treatment or electroless copper earlier with its metallization, and then compound with it in the casting cycle of aluminium alloy, has solved the problem of carbon cloth and aluminium alloy moistening badness, associativity difference.The material of processing has high specific strength and specific modulus, and the distribution of the shape of finished product and internal carbon fibers cloth thereof, the composition of aluminium alloy are all controlled.
Summary of the invention
The objective of the invention is to overcome carbon cloth and be difficult to the compound shortcoming of going in the aluminium alloy and combining difference, a kind of have high specific strength, specific modulus and the carbon cloth distribution is controlled, al alloy component is controlled carbon cloth-Al alloy composite and preparation method thereof are provided.
The present invention solves the problems of the technologies described above the technical scheme of being taked: make its metallization on the carbon cloth surface through copper facing, prevent under hot conditions, to take place weightless when having improved with the liquid aluminium wetability again.In the process of making fusible pattern, carbon cloth is arranged on request, the molten aluminium alloy of the required composition of casting obtains final finished again.
The preparation method of the above-mentioned carbon cloth-aluminium alloy with high specific strength and specific modulus is following:
Step 1: the size according to carbon cloth in the finished product is carried out cutting to it, punches on demand at its edge.Again to its remove photoresist, alligatoring, neutralization, sensitization, activation, reduction handle;
Step 2: the method that adopts electro-coppering or electroless copper is in carbon cloth surface plating.Take out the back and wash 15min, drier 20min in 70～80 ℃ hot blast with deionized water;
Step 3: make the fusible pattern formwork by the dimensional requirement of required finished product and the distribution requirement of internal carbon fibers cloth thereof.With mechanical means carbon cloth is fixed in formwork;
Step 4: smelting aluminium alloy, need add alloying element and skim by composition, and use aluminium film parcel refining agent to carry out degasification, add and cast after stirring the modulation cast temperature after the alterant.Cooling means is an air cooling.
The present invention obtains carbon cloth-Al alloy composite with respect to existing through pasting, and it is advantageous that:
(1) makes its metallization on the carbon cloth surface through copper facing, prevent again when having improved weightlessness takes place under hot conditions, make to become feasible through casting method acquisition carbon cloth-Al alloy composite with the liquid aluminium wetability.
(2) carbon cloth that obtains through casting method-Al alloy composite interface combines good, and difficult taking off taken out, and guaranteed the high ratio modulus of material.
(3) distribution and the al alloy component of carbon cloth in aluminium alloy all can be controlled.
