摘要
茂金属聚乙烯弹性体 (m PE)作为一种全新的弹性体品种 ,特别适合于 PP的增韧改性。然而 ,和其它弹性体一样 ,m PE的加入不可避免地引起 PP的刚性和强度降低。为了补偿因加入弹性体带来的刚性和强度的损失 ,采用短玻璃纤维 (SGF)对 PP/ m PE共混物进行增强 ,从而制得 PP/ m PE/ SGF三元共混复合材料。采用滞后测量法 ,分别对 PP/ m PE共混物和 PP/ m PE/ SGF三元复合材料的动态力学性能进行了研究。结果表明 。
The application of polypropylene (PP) is limited by its poor impact strength at low temperatures, which is frequently improved by the introduction of elastomers. However, a simultaneous decrease of the stiffness of the overall blend is inevitable. The PP/mPE blend was reinforced with short glass fiber (SGF). The dynamic properties of the PP/mPE/SGF composite were examined by means of the hysteresis measurement method with the stepwise load increase procedure and the single load level procedure. The results show that the PP/mPE/SGF composite has a very high dynamic modulus and a very high dynamic load limit.
