#13650, Damage Sensing of Conductive Glass/Carbon/Intra-ply Glass-carbon Laminated Composites under Dynamic Shear Loading

An experimental study is preformed to investigate the electro-shear response of glass/carbon/intra-ply glass-carbon laminated composites under dynamic shear loading. A three-dimensional conductive network is generated inside the composites by embedding carbon nanotubes (CNTs) in an epoxy matrix. CNTs were evenly dispersed in the epoxy by a combination of ultrasonication and shear mixing. The composites were created through a vacuum infusion process. A unique four circumferential probe measuring technique was used to measure the electrical response during dynamic shear loading. A double-notch specimen is prepared in this study to investigate the shear behavior of composites. Conventional split Hopkinson pressure bar apparatus is used to perform dynamic shear test. A correlation between electrical response and the shear deformation is investigated. Experiments are in progress and the results will be presented at the conference.
