Description
Technical field
The present invention relates to a kind of method of producing automobile brake disc, especially relate to a kind of method that carbon pottery automobile brake disc is produced in a step densification.
Background technology
Disc brake is the stopper that current passenger car the most generally uses, it have structure simple, be swift in response, the advantage such as effect stability, easy-maintaining.Retarding disc is the core component of disk braking system, and its performance decides the driver comfort of the braking safety of automobile.Now widely used disc brake material is cast iron, and it has easily processing and the advantage such as wear resistance is better, but it also has shortcomings such as quality is large, thermostability is poor, get rusty easily, brake noise is large.
Along with the development of Manufacturing Technology for Automotive Parts, retarding disc is just lighter towards quality, frictional coefficient is larger and the better future development of weather resistance.In the face of passenger car is to the active demand of high-performance retarding disc, research and development Novel brake disk material not only has major and immediate significance, but also has huge application value.
Carbon fibre reinforced ceramics retarding disc, adopt carbon fiber as a class friction materials of strongthener, it takes full advantage of carbon fiber in physicals, has the features such as intensity is large, modulus is high, density is little, heat conduction is good, high temperature resistant, rub resistance, Heat stability is good, has again the features such as the high rigidity of stupalith concurrently simultaneously.Carbon fiber plays the effect of bearing load in carbon ceramic composite material, and pottery and carbon basal body play the effect of transmitted load in carbon ceramic composite material.
Carbon fiber whether can play a role in carbon ceramic composite material depend on pottery and carbon basal body whether fine and close, so densification process is the key of the performance that decide carbon ceramic composite material.First the first step prepared by carbon ceramic composite material is that carbon fiber knit is become precast body, then introduces in precast body by pottery and carbon element presoma, and make carbon element and pottery be combined the matrix material forming densification with carbon fiber by Pintsch process, this step is called densification.
The densifying method of current carbon ceramic composite material mainly comprises several as follows: (1) chemical Vapor deposition process, by pottery and the at high temperature cracking of carbon element precursor gas, makes pottery and carbon deposition on carbon fabric perform to reach the object of densification; (2) liquid-phase impregnation process, by impregnated carbon fiber in carbon element precursor liquid, then curing molding, then put into High Temperature Furnaces Heating Apparatus and carry out cracking, finally go deep into carbon carbon base substrate to reach densification object with molten silicon; In above-mentioned technique, (1) preparation technology's cycle is long, and gas effciency is low, and cost is high, and deposition later stage surface ventilate is blocked, and needs continue deposition after processing, complex process.Technique (2) is because splitting gas effusion causes matrix material void content high in Pintsch process process, and need repeatedly to flood-Pintsch process circulation, the process time is long, density is on the low side.
Summary of the invention
In order to overcome the deficiency that existing densification process exists, the object of the present invention is to provide an a kind of step densification to produce the method for carbon pottery automobile brake disc, having obtained higher density carbon ceramic composite brake disc by a step densification, strengthen ceramic automobile retarding disc.
The technical solution used in the present invention adopts following steps:
Step one: the braiding of carbon fabric perform
Carbon fibre tow is carried out plain weave or satin weave becomes carbon cloth, carbon cloth edge cleavable polymer line carries out lockstitching a border in case the dislocation of blocking fibre bundle;
Step 2: the preparation of carbon fibre initial rinse stain body
Graphite Powder 99, silica flour and resin-oatmeal are carried out mixing to be dissolved in dehydrated alcohol, and the mass ratio of Graphite Powder 99, silica flour, resin-oatmeal and dehydrated alcohol is 30-60:2-20:30-70:70-90, fully stirs and makes soilless sticking powder in solution; This solution is evenly coated in advance the surface of carbon cloth, then fully dries at normal temperatures, obtain carbon fibre initial rinse stain body;
Step 3: the compression molding of carbon fibre initial rinse stain body
Carbon fibre initial rinse stain body is carried out lamination, and fiber architecture direction and next layer of offset angular of every one deck make the fiber architecture direction of adjacent two layers not identical; Then the carbon fibre initial rinse stain body after lamination is placed in the die cavity of molding die, initial press is to the pressure of 10-30MPa, keep initial press pressure to be first warming up to 120 DEG C, finally keep that pressure is constant is warming up to 180 DEG C, be incubated and be cured formation carbon fibre preform in 30 minutes;
Step 4: the processing of carbon fibre preform
Carbon fibre preform is carried out processing punching, after excising unnecessary corner, effects on surface carries out polished finish;
Step 5: the charing of carbon fibre preform
Be placed in by carbon fibre preform in charring furnace and carry out charing process, carbonization temperature is 1400 DEG C, finally obtains carbon ceramic Moving plate.
Cleavable polymer line in described step one is polypropylene fibre or terylene.
Carbon fibre tow in described step one is the carbon fibre tow of 1K, 3K, 6K or 12K.
The resin-oatmeal of described step 2 is adopted as high carbon residue resin or pitch.
The Graphite Powder 99 of described step 2 and silica flour are 10000 orders.
The solution banister brush that described step 2 obtains evenly brushes the surface at carbon cloth.
Lamination is carried out again after the carbon fibre initial rinse stain body of described step 2 carries out cutting.
Protect by argon gas, nitrogen or vacuum during charing process in the charring furnace of described step 5.
The invention has the beneficial effects as follows:
The additive such as Graphite Powder 99, silica flour and mixed with resin dissolve by the present invention, are then coated on carbon cloth in advance, then carry out compression molding charing, finally obtain carbon fibre reinforced ceramics composite brake dish.
The present invention and Traditional liquid phase flood the interpolation distinguished and be Graphite Powder 99 and silica flour, like carbonization process rate of change of the density less, obtain the carbon ceramic composite brake disc of greater density by one-step moulding charing, the preparation cycle overcoming vapour deposition and liquid impregnation method be long, the shortcoming such as the difficult control of process.
