Powder Bed Fusion of the Polyaryletherketone and Composites with High Performance-Research Status and Challenge

Powder Bed Fusion, which is a kind of Additive Manufacturing processes, uses the polymer powder and its composite powder as raw material. It could directly fabricate the polyaryletherketone (PAEK) and its composites with high me-chanical performance. By this technology, the parts with complex geometries could be prepared without any tooling or molding process, which provides a solution for structure optimization design and rapid development for high performance composite parts in the aerospace and automobile industry. In this paper, research status of the powder bed fusion of polyaryletherketone and its composites at home and abroad were introduced. The powder bed fusion system for PAEK, raw materials, process parameters, the enhanced PAEK composites and mechanical performances were discussed. At last, the challenges about the application of this technology were analyzed.
