Electro-Conductive Property of Polymeric Composite under Impact Loading Using a Modified SHPB

Abstract:

In order to detect the variation of electro-conductive property of polymeric composite under impact loading, a modified split Hopkinson pressure bar (M-SHPB) is suggested. Such M-SHPB is constructed by designing a new test electrocircuit, and connecting it to the specimen and oscillograph. On the other hand, a copper foil cover is designed and placed on the whole SHPB equipment for avoiding interference of electromagnetic wave existing in the testing environment. By means of M-SHPB, the relation between the resistance and dynamic strain is effectively detected.
