| 摘 要： | 对SF-TPU(短纤维－热塑性聚氨酯 )复合材料线热膨胀性能进行了理论与实验研究,考虑了短纤维取向分布的影响,建立了SF-TPU复合材料线热膨胀系数理论预测方程,理论预测与实验结果吻合较好。实验还表明,纤维取向因子fp与SF-TPU复合材料线热膨胀系数有很好的对应关系。

| Abstract: | Based on theoretical and experimental study, the linear thermal expansion coefficient prediction theory was established on short fiber thermoplastic composite and the short fiber orientation and distribution was taken into consideration. The results show that the final equation gives a good prediction of the thermal expansion coefficient of SF-TPU composite. |

| Keywords: | SF-TPU composite linear thermal expansion coefficient fiber orientation |
