    摘要: A wet friction material is mainly composed of a fiber base material, a filler, an friction adjusting agent and a thermosetting resin. The wet frictional material is prepared by impregnating with a liquid thermosetting resin a paper formed by mixing a paper-forming solid thermosetting resin with a fiber base material as at least a part of filler, and then applying heat to the paper so that it is hardened. The solid thermosetting resin is preferably a phenol resin. The liquid thermosetting resin is preferably made of a silicone resin represented by the following average composition formula and the amount of trifunctional unit monomers (RSiO3/2 in which R represents a substituted or unsubstituted monovalent hydrocarbon group) in monomers constituting said silicone resin is from 40 to 100 mol-%: (R1)a(OR2)bSiO(4−a−b)/2.

    摘要: A wet frictional material having a high heat resistance, excellent durability and superior initial conformability. The wet frictional material contains a fiber base material, a filler, a frictional adjustment agent and a thermosetting synthetic resin. The thermosetting synthetic resin comprises a silicone resin represented by the following average formula. The silicone resin contains a trifunctional unit (RSiO.sub.3/2) (where R represents a substituted or unsubstituted monovalent hydrocarbon group) in an amount of from 40 to 100 mol % of units constituting the silicone resin:(R.sup.1).sub.a (OR.sup.2).sub.b SiO.sub.(4-a-b)/2where R.sup.1 represents a substituted or unsubstituted monovalent hydrocarbon group, and R.sup.2 represents a hydrogen atom or an organic group having from 1 to 10 carbon atoms, and 0.2.ltoreq.a.ltoreq.1.8 and 0
