  • Damage localization was performed for the typical carbon fiber (CF) and glass fiber (GF) reinforced epoxy composite laminates through in-situ measurement technology. The electrode array was developed by utilizing the conductivity of CF reinforced epoxy composite laminates. The influence of plate thickness on the damage localization was investigated. For non-conductive GF reinforced epoxy composite laminates, multi-walled carbon nanotubes coated GF bundles sensors (MWCNT@GF) were fabricated, and the sensors were embedded into the laminates to form the sensor network. The influence of different incident angles on the localization was investigated. For the above two methods, an impact damage localization algorithm was developed and compiled. The results show that the damage position of CF/epoxy and GF/epoxy composite laminates can be located with high accuracy by using the self-resistance of CF and embedding MWCNT@GF sensors.
