本文分别将Kerner和van der Poel提出的两种平均区域理论应用于几种双组分弹性体共混物中,并将理论计算结果与实验得到的共混物在小形变下的动态性能加以比较。尽管共混物的微观结构较复杂,但从理论上仍能模拟含有彼此轮廓分明的基质材料和分散相(包容体)的共混体系。然而,用Kerner或van der Poel理论不能准确地 模拟具有连续形态的共混物。
In this paper, two kinds of average area theory proposed by Kerner and van der Poel are respectively applied to several kinds of two-component elastomer blends, and the theoretical calculation results are compared with the dynamic properties of the obtained blends under small deformation . In spite of the complex microstructure of the blends, it is theoretically possible to simulate blends containing well-defined matrix materials and disperse phases (inclusions). However, blends with continuous morphology can not be accurately modeled using the Kerner or van der Poel theory.
