| 摘要: |
| 针对黄麻纤维增强聚氨酯复合材料的弯曲性能,采用正交实验的方法,研究了纤维质量分数、纤维长度、成型压力和纤维表面处理方法四个因素对其的影响.通过对实验结果进行方差分析和极差分析,对工艺参数进行了优化.研究结果表明:纤维表面处理方法为复合处理、纤维质量分数为15%、成型压力为80t、纤维长度为25mm时,复合材料弯曲性能达到最优.该结果与玻纤、碳纤增强聚氨酯复合材料制品作相应的对比,并为提高实际生产的制品质量提供了理论依据. |

| Abstract: |
| The influences of fiber mass content,fiber length,modeling pressure and fiber surface process methods on bending property fiber renforced polyurethane composites were investigated by orthogonal experiments.Based on the variance analysis and range analysis of test results,the technological parameters were optimized.The research results show that:when fiber surface is treated by composite process,fiber mass content is 15%,modeling pressure is 80t,fiber length is 25mm,the composites get the optimal bending property.The result was compared with the corresponding research of glass fiber and carbon fiber reinforced polyurethane composites,and can also provide a theoretical basis for improving the quality of products in actual manufacture. |
