| 中文摘要: |
| 研究了玻璃短纤维-热塑性聚氨酯复合材料中短纤维用量对应力-应变曲线、拉伸强度和撕裂强度的影响。试验结果表明，随着复合材料中短纤维用量的增大，复合材料的刚性明显提高、应力-应变曲线从典型的粘弹性曲线变为弹性特性曲线、拉伸强度增大（短纤维用量超过11份），横向撕裂强度远低于纵向撕裂强度。 |
| 英文摘要: |
| The influence of short fibre level in the glass short fibre/thermoplastic PU composite on its stress-strain plot，tensile strength and tear strength was investigated.The results showed that the stiffness of composite increased significantly，the typical viscous-elastic plot changed into elastic one，the tensile strength increased(when the short fibre level was beyond 11 phr)，the transversal tear strength was much lower than the longitudinal one as the short fibre level increased. |
