摘要
Abstract
Scanning electron microscope (SEM) was used to study the morphologies of 3 kinds of domestic T800 carbon fiber (CCF800). Infrared spectrogram was used to analyse the structure of CCF800 sizing agent. In order to study the hygrothermal properties of domestic CCF800/epoxy composites, moisture absorption behavior and interlaminar shear property under hygrothermal environment were tested. Furthermore, SEM was used to study the interface between carbon fiber and epoxy after hygrothermal treatment. The results show that the morphologies of the 3 kinds of CCF800 are similar, while the chemical structures of sizing agent have a difference. The three kinds of CCF800/epoxy composite share the similar saturated moisture absorption period, that is about 54 days. And 95% saturated moisture absorption period is also the same, that is about 30 days. However, there is a obvious difference in saturated moisture absorption. In CCF800-3 sizing agent, the highest content of hydroxy leads to the highest moisture absorption rate of its epoxy resin matrix composite, and the interlaminar shear strength decreases most obviously under the action of high temperature and high humidity.关键词
