Abstract

A new experimental technique by means of split Hopkinson tensile bar (SHTB) at elevated temperature of 800 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 and 800. 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, and we attribute it to the oxidation or partial oxidation of the carbon fibers under dynamic loading at elevated temperature.
