LAMINATED COMPOSITE MATERIAL OF HIGH MOLECULAR WEIGHT POLYETHYLENE AND PHENOLIC RESIN AND THE PROCESS FOR ITS MANUFACTURE

摘要

A laminated composite material is disclosed which comprises a high molecular weight polyethylene with a viscosimetrically determined molecular weight above 500,000 and a phenolic resin. Also disclosed in a method of securing high molecular weight polyethylene to a phenolic resin composition by employing an ethylene copolymer thermoplastic bonding agent. The material possesses improved firmness, hardness and heat resistance and is useful in a variety of industrial fields, particularly where a combination of strength and heat resistance with impact and shock absorbing qualities is required. The material is particularly useful for the construction of apparatuses such as, by way of example only, weaving loom parts and brake linings in the motor industry. The material is also useful in railway track construction.
