Abstract
A novel experimental method for characterizing properties of carbon fiber-reinforced plastics under impact loading was proposed in this study. The dynamic compressive test was carried out by using a Split Hopkinson Pressure Bar (SHPB) system. A zinc buffer was used to reduce the oscillation of the specimen, and consequently the relation of stress-strain could be estimated precisely. The longitudinal strain of gage area could be estimated from the nominal deformation of gage area, and consequently the failure process could be grasped in detail from the relation of stress-strain. The dynamic compressive strength of the material was slightly higher than the static compressive strength.
