| 英文摘要 | In this study, GF/EP composite laminates with an epoxy matrix modified by carbon black (CB) nanoparticles of 2.0 wt% and copper chloride (CC) were manufactured using the vacuum assisted resin infusion (VARI) method. The addition of CB nanoparticles and CC substantially improves electrical conductivity of GF/EP composites in all three principal directions with percolation network of CB nanoparticles. The addition of CB nanoparticles increases both initiation and propagation values of modes I and II interlaminar fracture toughness of GF/EP composite laminates. The change in electrical resistance was used as a damage index to monitor delamination growth. With the damage index for individual pathways of a network in GF/EP quasi-isotropic laminates with CB and CC. An electrical resistivity tomography method was successfully developed to locate and quantitatively assess growth of transverse impact damage in the GF/EP composite laminates. |
