| 摘 要： | 茂金属聚乙烯弹性体(mPE)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,mPE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/mPE共混物进行增强,从而制得PP/mPE/SGF三元共混复合材料。采用滞后测量法,分别对PP/mPE共混物和PP/mPE/SGF三元复合材料的动态力学性能进行了研究。结果表明,这种复合材料具有非常高的动态弹性模量和动态负荷极限。

| Abstract: | 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 stiffness of the overall blend is inevitable. In this research, PP/mPE blend was reinforced with short glass fiber (SGF). The dynamic properties of PP/mPE/SGF composites were examined by means of hysteresis measurement method with the Stepwise Load Increase Procedure and Single Load Level Procedure. The results show that PP/mPE/SGF composites have a very high dynamic modulus and dynamic load limit. |
