Unlike synthetic fibers, bast fibers are made up of bundles of fibers. These bundles are broken down mechanically or chemically to achieve the fineness required. The degree of this breakdown, in turn, dictates their end use.

Bast fiber can be used as a reinforcement friction raw material for making non-asbestos brake pad, brake lining, clutch facing and paper based friction material.

bast fiber can improve friction material stability performance  and reduce material shrinkage and expansion performance during braking.

bast fiber can resist corrosion on friction material surface, especially corrosion by electrochemical corrosion of metal fiber is affected by environment.

using bast fiber making friction material and the product have more stomata, that can reduce the braking noise. For bast fiber soft character can reduce shaking during braking.

The price of bast fiber is very low than any other raw material.
