Through being used as brake material.Before the 1970s and 1980s in last century asbestos friction material as traditional product always by people
Class is largely used, after this, because known widely asbestos can cause pulmonary lesion and celiothelioma and relevant with the generation of lung cancer.
International medical oncology discussion in 1972 confirms that asbestos fibre contains carcinogen, hereafter, friction goods without asbestos and nothing
Pollutionization is increasingly becoming the common recognition of world's sexual development.
With the development and the raising of modern society's environmental consciousness of auto industry, the condition of work of automotive brake friction material
It is increasingly harsher, to its performance requirement also more and more higher, for example require brake friction material have enough and stable coefficient of friction,
Good thermal conductivity, larger thermal capacity, certain high temperature mechanical strength, good wearability and block resistance, it is difficult scratch
Mating plate, noiseless, low cost, environmentally safe etc..Current most widely used brake friction material has two classes, and a class is
Using the semimetal braking friction material of Stainless-steel fibre, the shortcoming of this kind of material is to cause product when dosage of steel fiber is excessive
Excessive high hardness, easy-to-rust, easily cause shriek and produce and tremble during braking;Another kind of is without asbestos organic friction material, mainly
Be addition glass fibre, potassium titanate crystal whisker or Fanglun slurry cake etc. as reinforcing material, but aramid fiber is expensive, shredding compared with
Difficult the problems such as, limits the application of the material.
Therefore, in view of the above-mentioned problems, the present invention proposes a kind of new technical scheme.
