Abstract

A thermosetting resin composition modified by a plant-based biomass, more specifically a thermosetting resin composition capable of giving sufficient bending strength to a friction material even in the case of using as a resin composition for a friction material is provided. A thermosetting resin composition includes a lignin derived from a lignocellulose, a lignocellulose fiber derived from the lignocellulose, and a thermosetting resin and the lignin derived from the lignocellulose and the lignocellulose fiber derived from the lignocellulose are dispersed in the thermosetting resin. A method for producing a thermosetting resin composition includes: mixing a plant-based biomass, a first acid and phenol, and heat-treating a mixture thereof, thereby obtaining a phenol solution in which a lignin and a lignocellulose fiber are dispersed in the phenol; and reacting the phenol solution with an aldehyde in the presence of a second acid, thereby obtaining a thermosetting resin composition comprising the lignin dispersed and the lignocellulose fiber dispersed.
