ANTIFRICTION AND CONSTRUCTION MATERIALS BASED ON MODIFIED PHENOL-FORMALDEHYDE RESINS REINFORCED WITH MINERAL AND SYNTHETIC FIBROUS FILLERS

摘要

Novel polymer composite materials (PCM) based on resole phenol-formaldehyde resins modified with polyamide and reinforced with a combination of organic and inorganic fibrous fillers have been developed. PCM are characterized by a Charpy impact strength of up to 250 kJ/m~2, an ultimate strength in static bending of up to 468 MPa, an ultimate strength in compression of up to 178 MPa, a Martens thermal stability of up to 300°C, a friction coefficient of up to 0.12, and mass wear of up to 0.76 mg/(cm~2.km). They can be used for the fabrication of products intended for antifriction and constructional purposes.
