Hygrothermal properties of domestic T800 carbonfiber/epoxy composites
Journal of Aeronautical Materials, 2019 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 ...
