Title:
湿式摩擦材用樹脂組成物および湿式摩擦材
Document Type and Number:
Japanese Patent JP4053330
Kind Code:
B2
Abstract:
A resin composition for wet friction materials contains as a main component a phenolic resin formed as a result of the reaction between phenols and aldehydes in the presence of a basic catalyst, and a particulate filler having a specific surface area of 35 to 410 m<2>/g as an additive. A wet friction material is formed using the resin composition for wet friction materials described above as a binder. The thus formed wet friction material exhibits a small initial rate of change in friction coefficient, a large positive gradient of Deltamu-V characteristic, and excellent durability.
