摘要

A new experimental technique by means of split Hopkinson tensile bar (SHTB) at elevated temperature of 800°C was introduced. By this technique we carried out an investigation into the dynamic properties of 2D C/SiC composite at both room and elevated temperature of 20°C and 800°C. It was found that the failure strength and strain of 2D-C/SiC composite decreases significantly with the increase of temperature. Observation of SEM micrographs of failed specimen fracture under dynamic tensile loading at both temperatures reveals a comparatively smooth fracture and short fiber pull-out at elevated temperature of 800°C, and we attribute it to the oxidation or partial oxidation of the carbon fibers under dynamic loading at elevated temperature.
