本文进行了大量的复合材料线性蠕变实验,对我们提出的复合材料蠕变混合律进行验证。实验结果表明,该混合律在线性范围内对复合材料蠕变预测是相当精确的。从实验中首次得到了聚合物泊松比随时间的变化关系。
In this paper, a large number of linear creep experiments of composites were carried out to verify the creep mixing law of composites. The experimental results show that the mixed law predicts the creep of composites to be quite accurate in the linear range. The change of Poisson’s ratio of polymer with time was obtained for the first time from the experiment.
