Synthesis Of Phenol Formaldehyde And Friction Materials Reinforced Brake Liner Material
Abstract
Abstract- The present invention relates to phenol formaldehyde resins and a process for making the resins. In
particular, the present invention is directed towards phenol formaldehyde resin having relatively high
formaldehyde to phenol ratio when compared with conventional resins. Manufacturing of Phenol formaldehyde
resin containing groups of phenols and formaldehydes. Phenol formaldehyde resin(PF) include synthetic
thermosetting resins such as obtained by the reaction of phenols with formaldehyde. The optimum properties of
a good friction material are an adequate coefficient of friction for the expected usage, ability to retain a constant
coefficient of friction under varying conditions. The friction material is made by molding and curing process
with a composition of iron fibers, phenol formaldehyde, silicon carbide & Carbon Nanotubes as the major
ingredient. Phenol resin is used as a binder in preparing the friction material. The graphite is inseparably
contained in the mixture of cashew Nut shell liquid and based on the experiments the material shows a high
frictional coefficient and reduced wear rate when compared with the literature available
