Abstract

Sliding bearing materials are made by distributing a powdered synthetic resin or synthetic resin-PTFE mixt. in a fibre fleece or fabric which is esp. a high polymer material, and pressing the prod. to form the bearing materials. Provides a cheap and simple method for making attention-free bearing materials, requiring less process stages than processes using liquid resin systems. The synthetic resin is pref. a phenolic resin contg. 5-25% PTFE powder with a max. particle size of 0.4 mm. The carrier material is e.g. a polyamide fabric. the resin powder can be distributed in the fibre fleece by brushing, spreading, etc., after which the material may be subjected to a short heat treatment at temps. up to the m. pt. of the resin to fix the resin on the fabric. The material can then be moulded to shape under heat and pressure as necessary.
