La description
In the last several years, the NFJ Foamy Fiber (porous
strengthening material) has been a novel material used in the
polymer based-friction materials. With the development of high
speed and heavy railway vehicles, and the requirement of
environment protection, it is demanded that the friction materials
should provide some new properties. It is widely recognized that
the next generation friction materials should be light-weight,
porous, elastic, low density, have rough surface, decrease the
dosage of polymers, including rubber and resin used as binders in
the friction materials. This will reinforce the mechanical and
friction properties of the braking components, reduce the noise and
increase the vehicle comfort. The enhanced binding strength
of inorganic materials can reduce the addition of nonferrous
metals, which will prevent their harm to the human beings.
In recent years, the developed countries have set up the policy
that the nonferrous metals are forbidden to be used in friction
materials due to the fact that the dust induced during the wear of
friction materials can do harm to human beings, and contaminate
water once it enters into the earth.
Our company has developed foamy fiber, which is a porous
strengthening material. It is mainly made of iron together with
carbon less than 0.*2 wt.%. Fe is an element beneficial to the
human beings. The NFJ foamy fiber, which is produced through
special technique, is loose, porous, plastic, low density and with
rough surface and resistant to rust. It has been widely used in the
friction materials for railway and automobiles.
