Study About Mechanical Property and Machinability of Carbon-Fiber Reinforced Polyetheretherketone

摘要

The carbon-fiber reinforced PEEK (CF/PEEK) is a high performance macro-molecular compound with particular micro-structure and mechanic property. It has been shown better application properties in various aspects and widely used in structural components. The purpose of this paper is to investigate the microscopic mechanical property and machinability of CF/PEEK. The microscope mechanical property of CF/PEEK is studied by nano-indentation while the single-point diamond turning (SPDT) is used to study the machinability. Then the surface roughness and form accuracy of the machined surface are measured. The experiment results show that CF/PEEK has good machinability while the microscopic mechanical property is not uniform.
