An investigation of the microstructure and tribological behavior of polyether ether ketone composites fabricated by extrusion?based additive manufacturing
Carbon fiber reinforced polyether ether ketone (CF/PEEK) composites are widely used as tribo?materials in aerospace and automotive industry. To amplify the industrial utilization of extrusion?based additive manufacturing fused deposition modeling (FDM) in fabricating CF/PEEK tribo?composites, the composites' microstructure?property relationship was studied with respect to carbon fiber content varied between 5?wt% and 30?wt%. It was revealed the incorporation of carbon fibers helped enhance the mechanical strength of PEEK greatly with an optimal content of 5?wt%, at which the composite material exhibited the highest crystallinity as well as the best mechanical performance. Tribological tests indicated that CF/PEEK composites were more suitable for high speed and heavy load conditions especially for 20?wt% CF/PEEK, which was associated with the establishment of high quality transfer films covered on counter steel surfaces. The present work provides a simple and low cost way of fabricating high performance PEEK composites used as tribo?materials.This article is protected by copyright. All rights reserved.
