摘要
用扫描电镜研究了硅烷改性玻璃短纤维(T型SGF)填充氯化聚乙烯(CPE)复合体系及未改性玻璃短纤维(O型SGF)充CPE复合体系的毛细管挤出物形态,结果显示出剪切等流动因素对玻璃短纤维(SGF)的取向性和分散性有很大影响;不同SGF复合体系的界面状态不同,SGF分散情况也存在着较大差异;复合材料在毛细管流变仪中均存在着明显的旋转流动。
The morphology of capillary extrudate of chlorinated polyethylene (CPE) reinforced by short glass fiber (SGF) composites which were treated (Ttype )or untreated (O type ) with silane coupling agent were investigated by scanning electron micrography . The extrudate was brittle ruptured at low temperature , with axial section A and radial section D .The electron micrograph of axial section A shows that , for T type CPE/SGF composites , coupling agent increases the binding force between two phases , the matrix is towed obviously , thus decreases the elasticity of the composites . For O type CPE/SGF composites , there exists obvious interface between SGF and matrix , forminghallow holes or pipes , which decrease the mechanical properties of the composites .The micrography of radial section D shows that the elasticity of T type CPE/SGF composites is lower than that of O type .The shear function has great effect on orientation and dispersion of glass fiber .differences between two types of interface state of the composites make glass fiber dispersion great difference , and the composites both have rotational flow in the capillary .
