Abstract
A thermosetting resin composition for a friction material includes a thermosetting resin and a lignocellulose nanofiber dispersed in the thermosetting resin. A method for producing a thermosetting resin composition for a friction material includes a first step and a second step. In the first step, a plant-based biomass containing a lignocellulose is mixed with a dispersion medium to obtain a mixture thereof, and the mixture is subjected to a defibration treatment to obtain a slurry of a lignocellulose nanofiber. In the second step, phenol is reacted with an aldehyde in the presence of an acid catalyst to obtain a thermosetting resin, and the slurry is added to the thermosetting resin. The lignocellulose nanofiber is dispersed in the thermosetting resin while removing the dispersion medium and unreacted phenol.
