Our previous study focused on not only how the physical properties of pad matrix strength and porosity depend on the titanates' crystal structure and shape, but also on the chemical properties of the titanates themselves.

As a result, it was found that the reaction that occurs on the friction surface of the titanate and the phenolic resin has an influence on the tribological performance of brakes. Our conclusion was that titanates affect the thermal reaction of phenolic resins.

Our newest study uses 1/7-scale dynamometer testing to further investigate the relationship between titanate compounds and phenolic resins. The results make clear that when titanate is added, μ is more stable than when not added. The results of chemical experiments showed that the products of pyrolysis are different when titanate is added or not added. Our conclusion is the property of the products of pyrolysis affects the stability of μ.
