摘　　要：为研发汽车内饰复合板材,以聚丙烯纤维(PP)、玻璃纤维(GF)和黄麻纤维为原料,利用针刺加固工艺制备针刺毡。以GF含量、黄麻纤维含量、针刺密度为因素,针刺毡的拉伸强力为指标,设计三因素三水平正交试验,优化针刺工艺。利用最优针刺工艺和烘燥冷压成型工艺制备复合板材,利用扫描电镜表征材料内部结构,并测试材料基本物理性能。结果表明:GF含量、黄麻纤维含量对针刺毡拉伸强力有显著影响;影响针刺毡拉伸强力的因素主次顺序为GF含量、黄麻纤维含量、针刺密度;优化后的针刺工艺制备参数为PP/GF/黄麻纤维比例60∶20∶20、针刺密度为300刺/cm^2;针刺毡纤维间黏合较好且分布均匀;样品拉伸性能和弯曲性能符合汽车衣帽架的要求,阻燃性能达标。To develop the automobile interior decoration composite board,needled felt was prepared with polypropylene fiber(PP),glass fiber(GF)and jute fiber as raw materials through needled strengthening process.GF content,jute fiber content and needling density taken as factors,the tensile strength of needle-punched felt as index,the orthogonal test of three factors and three levels was designed to optimize the needling process.The composite sheet were prepared by using the best needling process parameters and the drying and cold pressing process.The internal structure of the material was characterized by scanning electron microscope and its basic physical properties were tested.The results show that GF content and jute fiber content have significant influence on the tensile strength of needled-punched felt;the primary and secondary factors affecting the tensile strength of the felt are GF content,jute fiber content and needling density;the optimized needling process parameters are PP/GF/jute fiber ratio 60∶20∶20,needling density 300 needling/cm^2;the fibers are well bonded and evenly distributed;the tensile and bending properties of the felt meet the requirements of the car coat and hat rack,and the flame retardant performance meets the standard.
