Abstract

Official abstract text for this publication.

A thermosetting resin composition includes a lignin derived from a lignocellulose, a lignocellulose fiber derived from the lignocellulose, and a thermosetting resin. In the thermosetting resin composition, the lignin derived from the lignocellulose and the lignocellulose fiber derived from the lignocellulose are dispersed in the thermosetting resin.

First claim

Opening claim text (preview).

The invention claimed is: 1. A thermosetting resin composition comprising: a lignin obtained by decomposing a lignocellulose; a lignocellulose fiber obtained by decomposing the lignocellulose; and a phenol resin, wherein after the lignocellulose is decomposed, the lignin and the lignocellulose fiber obtained therefrom are dispersed in the phenol resin, and wherein a content of the lignocellulose fiber is 1 to 20% by mass. 2. The thermosetting resin composition according to claim 1 , wherein a content ratio between the lignin and the lignocellulose fiber is 1:1 to 1:10 by mass ratio. 3. The thermosetting resin composition according to claim 2 , wherein the lignocellulose fiber has an average fiber length of 1,000 μm or less. 4. The thermosetting resin composition according to claim 1 , wherein the lignocellulose fiber has an average fiber length of 1,000 μm or less. 5. A method for producing the thermosetting resin composition as described in claim 1 , comprising: mixing phenol with the lignin and the lignocellulose fiber to form a phenol solution; and reacting the phenol solution with an aldehyde, thereby obtaining the thermosetting resin composition comprising the lignin dispersed and the lignocellulose fiber dispersed. 6. The method according to claim 5 , further comprising melt-kneading the thermosetting resin composition. 7. A friction material comprising the thermosetting resin composition according to claim 1 . 8. The friction material according to claim 7 , wherein a content of the thermosetting resin composition is 5 to 15% by mass. 9. A friction material comprising the thermosetting resin composition according to claim 2 . 10. The friction material according to claim 9 , wherein a content of the thermosetting resin composition is 5 to 15% by mass. 11. A friction material comprising the thermosetting resin composition according to claim 4 . 12. The friction material according to claim 11 , wherein a content of the thermosetting resin composition is 5 to 15% by mass.
