The study investigates the cross-scale combination of carbon nanotubes and chopped carbon fibers as an enhancer for adhesive in thermoset composite bonded joints. The composites reinforced with the combination of CNTs and CCFs show higher strength, with over 30.8% improvement compared to composites reinforced solely with CCFs.
The cross-scale combination of carbon nanomaterials and macro-materials is a key application in the advanced manufacturing technology of composite materials. In this work, a cross-scale component of carbon nanotube combined with chopped carbon fibers (CNT-CCFs) prepared by the flame method was firstly used as an enhancer for adhesive. The effects of component on the mechanical and fracture properties of thermoset composite bonded joint were investigated. The composites reinforced with CNT-CCFs exhibit higher strength than the composites reinforced solely with CCFs, with over 30.8% improvement for the combined CNTs and CCFs toughened adhesive joints.
