聚醚醚酮材料改性、加工与应用

摘要

PEEK and the relevant composites are widely used in aerospace,automotive and medical field due to the perfect performances in thermal,mechanical and other properties. Properties of PEEK can be greatly improved by re⁃inforced modification with inorganic particles,glass fiber,carbon fiber etc. The PEEK and reinforced composites can be processed into different products by extrusion,injection molding and 3D printing,and applied in many engineering fields. This paper mainly reviews the recent investigations of researchers in China and abroad from three aspects which include reinforced modification,processing and application on PEEK.%聚醚醚酮（PEEK）及其复合材料在航空、汽车、医疗等领域具有很大的应用市场。通过增强改性，聚醚醚酮材料力学、热学等性能得到了很好提升，利用熔融挤出机、注塑成型机以及3D打印机等成型装备，将聚醚醚酮及其复合材料制备成不同类型的产品，以适用不同领域的材料需求。从聚醚醚酮的改性方法、制品成型制备以及主要应用领域3个方面，简要介绍了近些年国内外学者的研究工作与研究重点。
