Abstract

Epoxy carbon-fiber composite (FRP) has been widely regarded as premium construction material in automobile and leisure sporting good industries. In this research, the formation of residual strain in epoxy carbon fiber composites during curing was monitored using Fiber Bragg Gratings (FBG). Carbon-fiber composites were prepared under steady temperature gradient and the FBGs were embedded during FRP preparation process along axial fiber layout direction. The effect of residual stress to the dynamic tensile stress in these FBG imbedded carbon fiber composites was examined using modified Split Hopkinson Tensile Bar (SHTB). The relationship between residual stress and dynamic tensile stress in the FRP under a high strain rate ranging from 500 to 1000 s-1 was thus studied.
