Description
Technical field
The invention belongs to brake system of car technical fields, and in particular to a kind of non-metallic automotive brake block and its preparation side
Method.
Background technique
Brake block directly affects car steering performance as one of link important in entire braking system, braking ability
And concerning life security, especially some heavy-duty freight cars and car are when mountain highway is run at high speed, since brake is frequent
Braking causes brake block heat fading, causes brake efficiency to weaken or fail and particularly serious traffic accident occurs, give people's life wealth
Production brings huge loss.Traditional one, two generation brake blocks are easy to happen hot ceremonial dress for royalty and move back, wear away fast, braking stationarity when forcing dynamic
The outstanding problems such as difference and noise are big, can not adapt to the new demand of the modern means of communication.It studies and is suitble to higher speed, more may be used
By stabilization, good heat resistanceheat resistant Decay Rate, more environmentally-friendly and great replicability high performance brake material, meet the friendship of China's modern times
The demand of logical tool.
The brake block of fibre reinforced is the new hot spot of domestic and international new brake investigation of materials, has heat-resist, weight
Gently, the advantages that coefficient of expansion is small, wear-resistant and good heat resistanceheat resistant Decay Rate.Fibre reinforced brake material is broadly divided into carbon fiber
Dimension enhancing two classifications of carbon/carborundum based material and carbon fiber enhancement resin base composite material.Lot of documents is to domestic and international 9
Kind C/C composite airplane brake disc thermodynamics and friction and wear behavior are tested, the results showed that carbon matrix brake disc is every
It has excellent performance.It was found that bond vitrified and deformation also do not occur for 2000 DEG C of carbon/carbon compound material disc surface temperature, absorb heat function
Can, wearability and antifading is good and wear rate is low.Brake pad material is from carbon fiber skeleton structure, thickening technology, component
Etc. C/SiC brake material studied find that its average friction coefficient reaches 0.23, friction stability reaches 0.43, linear to grind
Loss rate is 9.3 μm/secondary face, and quality wear rate is 2.6mg/ face, and coefficient of friction is to braking number and surface temperature is unwise
Sense, there is no heat fading trend；The rubbing surface of sample worn surface formation continuous-stable.Carbon fiber can reduce compound after being added
The coefficient of friction of material, carbon fiber adding manner is different, also different to the influence of coefficient of friction；Detect the examination of different resins base
The frictional behaviour of sample, the results showed that its frictional behaviour is main related with temperature, and wear rate and coefficient of friction vary with temperature and become
Change, but correspond to different matrix, degree of susceptibility is different.
In terms of application achievements, patent CN104405804A and CN105156526A etc. provide various forms of carbon fibers and increase
Strong brake pad material and preparation method thereof, the carbon fiber introduced in improves the friction and wear behavior of brake block, but brakes
Appoint in piece component and so contain a large amount of metal materials, such as copper powder and metallic fiber material, these components are to improvement brake block
Require no any effect using modern automobile industries such as low noise comforts, instead exactly the origin cause of formation of brake block brake noise because
Element.Therefore, the new demand that high-performance and low-cost brake pad material is China's Modern Traffic transportation development is prepared.
