填充环氧树脂界面残余应力研究,Ⅰ.球面应力—光学等式

STUDIES ON REMAINED INTERFACE STRESS OF FILLED EPOXY RESIN I. SPHERIC SURFACE STRESS-OPTICAL EQUALITY

采用显微光弹法测量了橡胶填充环氧树脂(RMER)和玻璃珠填充环氧树脂(GMER)这两种复合体系中的界面残余应力,介绍了适用于这些体系的球面应力—光学等式,并观察了填料界面残余应力产生的光弹图像.

The remained interface stress in two composites - rubber-filled epoxy resin and glass mi-croballon-filled epoxy resin was measured with the microphotoelastic method and the photoelastic images of the remained interface stress of the fillers was observed. In this paper is introduced the spheric surface stress-optical equality suitable to these composite systems.
