提高聚醚醚酮（PEEK）和PEEK/碳纤维（PEEK/CF）复合材料的加工性能，同时减少对其它性能的影响是非常重要的。采用一种新型高温润滑剂GENIOPLAST PELLETS（GPPS）降低PEEK和PEEK/CF复合材料的熔体粘度。采用动态流变仪、万能试验机、扫描电镜（SEM）、热重分析（TGA）和差示扫描量热法（DSC）对PEEK/GPPS和PEEK/CF/GPPS复合材料进行了表征。结果表明，少量GPPS可降低PEEK/CF复合材料加工过程中的熔体粘度，改善碳纤维在PEEK基体中的分散均匀性，进一步提高PEEK/CF复合材料的拉伸强度，但对复合材料的热稳定性影响不大。
An improvement in the processability of poly(ether ether ketone) (PEEK) and PEEK/carbon fiber (PEEK/CF) composites with less influence on the other properties is important. A novel high temperature lubricant, GENIOPLAST PELLETS (GPPS), was used to decrease the melt viscosity of PEEK and PEEK/CF composites. PEEK/GPPS and PEEK/CF/GPPS compounds were characterized by dynamic rheometry, universal tester, scanning electron microscopy (SEM), thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results showed that a small amount of GPPS could decrease the melt viscosity of the compounds during processing, and improve the dispersion uniformity of the carbon fiber in the PEEK matrix, and further enhance the tensile strength of PEEK/CF composites, but have little effect the thermal stability of the compounds.
