腰鼓型密炼机转子的混合特性及其对碳纤维残存长度的影响

针对碳纤维（CF）增强硅橡胶复合材料的特点，提出了一种新型腰鼓型转子，并运用数值模拟软件对其混合特性和对复合材料中CF长度的影响进行了表征，并与实验结果进行了对比。结果表明,转子构型、转子转速、混合时间是影响纤维残存长度的主要因素;其中，DRI型转子对纤维的损伤较大，随着转速和混合时间增加，纤维损伤增加，残存长度减小。

Effect of Mixing Characteristics of Drum-type Rotors on Residual Fiber Length in Silicone Rubber/Carbon Fiber Composites

In this paper, a new drum-type rotor was designed on the basis of characteristics of carbon-fiber-reinforced silicone rubber composites, and its mixing behavior and effect on the residual fiber length in the silicone rubber/carbon fiber composites were analyzed by a numerical simulation software and then verified by experimental results. The results indicated that the rotor configuration, rotor speed and mixing time were major factors determining the residual fiber length, and the DR-I type rotor was found to damage the fiber more seriously. The fiber damage became more serious with increasing rotational speed and mixing time, thus leading to a decrease in residual fiber length.
