摘　　要：采用熔融挤出法制备了添加不同相容剂的聚丙烯/碳纤维(PP/CF)复合材料管道,通过管道长期耐压试验装置、电子万能试验机、冲击试验机以及扫描电子显微镜等方法,探究了不同碳纤维含量和长度及不同相容剂对PP管道力学、纵向回缩率、爆破强度等性能的影响。结果表明,碳纤维填充后的PP降低了PP/CF复合管道材料的整体纵向回缩率,增强了管道的爆破强度;相容剂的添加显著提高了其力学性能。In this work, the pipes based on the polypropylene (PP)/carbon fiber (CF) composites were prepared by melt extrusion using different compatibilizers. The effects of CF lengths and contents and compatibilizer types on the mechanical properties, longitudinal retraction rate and blasting strength of the pipes were investigated by means of a long-term pressure test instrument, computer-controlled electronic universal test machine, combined digital display and scanning electron microscope. The results indicated that the introduction of CF as a high modulus and low retraction filler reduced the overall longitudinal shrinkage of PP/CF composite pipes and enhanced the burst strength of the pipes. Meanwhile, the addition of compatibilizer improved the mechanical properties of pipes significantly.
