摘要/Abstract

摘要： 通过自制的热塑性缠绕成型设备制备了连续碳纤维增强PPS复合管材,并对其相关性能进行了考查。依据检测标准,对复合管材的ILSS(层间剪切强度)、结晶度、密度、吸水率、空隙率等性能进行了研究。结果表明,复合材料的空隙率在0.04%和0.05%时,其ILSS分别为33.25MPa和27.54MPa,空隙的存在导致管材的ILSS下降;在不同温度下对管材进行热处理,发现ILSS随着热处理温度的升高而增加。在不同测试环境温度下,ILSS随着环境温度的升高出现下降。在沸水中浸泡8h后,管材的吸水率仅为0.66%,说明管壁成型致密。通过表征分析,说明自制的热塑性缠绕成型设备可制备性能优良的热塑性复合管材。

Abstract: In this paper, continuous carbon fiber reinforced PPS pipes were fabricated by an own-designed filament winding machine and its relative performances were examined. According to ASTM D792 and D2344, voidage and ILSS of composites were measured. Meanwhile, the other characteristics (crystallinity, density water absorption ratio) of composites pipes were studied. The results showed that the voids mainly located between the carbon fiber. The presence of voids had an effect on the pipe ILSS and the ILSS deceased with the increasing of void content through the research. The ILSS of composites were 33.25MPa and 27.54MPa with 0.04% and 0.05% of the void volume fractions, respectively. At different temperatures for the heat treatment of materials, a conclusion could be drawn that the ILSS of composites increased with the growing of the heat treatment temperature. The influence of ambient temperature was also studied in a similar way and the ILSS of composites decreased as it increasing. Soaking in boiling water for 8 h, the water absorption ratio of composites was only 0.66%. The composite pipe has low water absorption ratio. The thermoplastic composites winding machine can produce thermoplastic composite pipe with excellent performance.
