摘要/Abstract

摘要： 为获得层间粘结性能优异的连续碳纤维增强聚醚醚酮复合材料(CF/PEEK)缠绕成型制品,以粉末浸渍法制备的CF/PEEK单向带为原料,采用自制的高功率红外加热热塑性复合材料缠绕成型设备,进行缠绕成型工艺的研究。以层间剪切强度(ILSS)作为评价缠绕制品性能的主要依据,分别研究了缠绕成型过程中的送料张力、下压辊压力、缠绕速率、加热温度、预热时间和冷却速率等关键工艺参数对CF/PEEK环制品性能的影响。实验结果表明,成型温度为410 ℃,预热为40 min,送料张力为8 kg,下压辊气缸压力为0.30 MPa,芯模转速为6 r/min,缓慢冷却条件下制得的缠绕制品性能最优,层间剪切强度达到(82.29±1.27) MPa,并据此制备出了CF/PEEK缠绕管道。

Abstract: In order to manufacture continuous carbon fiber reinforced polyetheretherketone composites (CF/PEEK) winding product with excellent interlayer adhesion performance, the CF/PEEK unidirectional tape prepared by powder impregnation process was used as raw material, and the winding forming process was studied by using a self-made high-power infrared heating thermoplastic composite winding forming equipment. The quality of the winding products were evaluated by testing the interlaminar shear strength. The effects of key process parameters such as feed tension, compaction force, winding rate, winding temperature, preheating time and cooling rate on the performance of CF/PEEK ring products were studied. The results showed that the winding products had an excellent performance manufactured under the optimal condition as follow: molding temperature 410 ℃, preheating for 45 minutes, feeding tension 8 kg, cylinder pressure of roller 0.30 MPa, mandrel rotating speed 6 r/min, and slow cooling condition. The interlaminar shear strength of the prepared CF/PEEK ring was up to 82.29 MPa. Based on the above research results, the CF/PEEK winding pipe was prepared.

Key words: CFRTP, polyetheretherketone, infrared heating, winding process, interlaminar shear strength
