Description
Technical field
The present invention relates to a kind of friction material, more particularly to a kind of composite fibre high-quality friction material and its preparation side
Method.
Background technology
Friction pair is machine driving and the significant components of brake portion, and it is related to the reliable of vehicle power transmission and control
Property.Friction pair is made up of friction plate and antithesis piece, and the performance of wherein friction pair depends primarily on the friction and wear behavior of friction plate.
Existing domestic friction plate has that frictional behaviour is unstable, wear rate is high and the low problem of heat resistance in use, still,
The serious performance for constraining the excellent mobility of assembly.Therefore, develop and match with high load capacity, high-energy, high-speed drive system
, the Novel friction plate that service life length, reliability are high and friction pair it is very urgent and necessary.
Friction material is the critical material for constituting friction pair, and the high performance grinding under high speed, severe duty is applied at present
Material mainly includes：Powder metallurgy friction material, carbon/carbon-carbon friction material, ceramic-based friction material, semimetal friction material and paper
Base frication material.
Compared with metal base frication material, non-metal base friction material has excellent tribological property, is current friction
One of material important development direction.The current non-metal base friction material mainly applied has carbon/carbon-carbon friction material, ceramic base friction
Material and paper friction material.
（1）Carbon/carbon-carbon friction material
Carbon/carbon-carbon friction material due to height than by force than mould, low-density, heat conductivility and frictional behaviour is excellent and high-mechanic energy
The outstanding features such as power, long life, than Metal Substrate brake material Mass lost 40%, the longevity is being used as aircraft finance lease
3-5 times of life extension, can be used for big energy brake, with high reliability and maintainability.Therefore, carbon/carbon-carbon friction material is extensive
Critical material as aircraft brake system.In the U.S., many military aircrafts use carbon/carbon brake disc, such as F-16, B-1
Deng；Domestic Zhongnan Polytechnic Univ, Northwestern Polytechnical University and Shenyang metal etc. preparation in carbon/carbon brake disc and its frictional behaviour
Research in terms of achieve abundant achievement.At present, it is domestic to prepare the process that carbon/carbon-carbon friction material uses and be mainly
CVD, haves the shortcomings that production cycle length, the small, cost of batch are high；Technique is prepared also in laboratory preparatory phase, at present still
Industrialization can not be formed.Above mentioned problem is to need to solve during carbon/carbon-carbon friction material develops.
（2）Ceramic-based friction material
Ceramic-based friction material can bear high surface temperature, with higher coefficient of friction, higher compression strength and relatively low
Thermal coefficient of expansion, slide abrasiveness and corrosion stability be good, is class important materials in Friction Materials field in recent years.Mesh
The more ceramic-based friction material of preceding research has Al2O3Base frication material and C/SiC friction materials, and with fiber reinforced ceramic
Friction material is important development direction, to solve the brittleness problems of ceramic material.
C/SiC friction materials have the performances such as density is low, intensity is high, high temperature resistant, thermophysical property are good, especially with friction
Coefficient is high and stably, and the advantages of influence to environment is insensitive, the advantage with substitution C/C friction materials is rubbed greatly by the U.S. four
Wipe Materials Co., Ltd and be set to aircraft friction material of new generation.Meanwhile, because of the friction and wear behavior that C/SiC friction materials are excellent, in height
The high energy such as fast train, automobile, aircraft, tank, which carry field, also to have wide practical use, thus C/SiC friction materials turn into current
One of focus of high-quality friction material research.Using chemical vapor infiltration（CVI）Association reaction molten liquid forming（RMI）System
It is high with kinematics and static friction coefficient for inexpensive, high performance C/SiC aircraft friction materials（Respectively 0.34,0.41）, it is wet
State is almost undamped（About 2.9%）, wear and tear small（About 1.9 μm）, the features such as stable friction performance.At present, the crisp of ceramic material is solved
Property is the research emphasis of ceramic-based friction material.
（3）Paper friction material
Paper friction material comes across late 1950s, is that yield is maximum in the world today, most widely used wet type is rubbed
Wipe one of material.Paper friction material is by cellulose fibre, high-performance fiber, special particle and additive and different viscous
Connect agent to be made, be soft and porous material, through-thickness even structure is interconnected between hole.When friction pair is not engaged
When, in hole can lubrication oil, when friction pair is engaged, oil flows out from porous material, so as to cool down friction surface.Paper base material
Material elasticity is good, can be distributed uniform load on the whole surface by deforming during engagement.But it is due to that it is organic structure,
Therefore the thermal conductivity factor of paper friction material, ratio of heat capacities copper base friction material are small.Meanwhile, excessive surface pressing can make material
Fiber binder below surface disconnects, and spot occurs in material or large area comes off, and causes material failure.
In summary, the high cost of carbon/carbon-carbon friction material, the fragility of ceramic-based friction material and paper friction material
Low-intensity is the bottleneck problem for restricting its large-scale promotion application, thus research has relatively low manufacturing cost, and with stabilization
The friction material and its friction pair of coefficient of friction, low wear rate and high-fire resistance energy are the developing direction of non-metal base friction pair.
