โœฆ Synopsis

The use of injection moulded thermoplastic composites is increasing, but withoutfillers, reinforcements, or lubricants, they are limited by their thermal behaviour. This study looks at four polymers -polyamide 46, polyphthalamide, polyetherimide, and polyphenylenesulphide -containing first glass fibres as reinforcement, and a second version with added PTFE. Two types of wear test were undertaken, sliding wear (pin-on-disc and block-on-ring), and reciprocally fretting wear. The test materials showed different wear rates both under different tests and at various temperatures.

## This paper presents the general results of an investigation of the friction and wear of a carbon-carbon (C/C) composite material in dry nitrogen and ambient air using a constant speed type of test apparatus. With brake applications in mind, much of the work has been carried out at experimental
