报告摘要：

In the past decades, extensive studies have been conducted for enhancing the mechanical performance of polymers using various nanofillers because of their ability to act as a reinforcing phase at the nanoscale. Some efforts have also been made to improve the performance of continuous fiber reinforced polymer composites and structures such as carbon fibre/epoxy (CF/EP) and glass fibre/epoxy (GF/EP) laminate with modified epoxy resins. This presentation is to articulate how the improvement for nanofiller-modified epoxy resins translates into CF/EP and GF/EP composite laminates. Some available data are reviewed, addressing the effects of nanoparticles and fabrication methods. In particular, some recent results on interlaminar fracture, impact damage resistance and compression after impact (CAI) on CF/EP and GF/EP composite laminates with nanosilica and carbon black are highlighted. The electrical conductivity based on percolation network of nanoparticles in GF/EP laminates renders a unique opportunity to monitor delamination growth and impact damage in GF/EP laminates based on electrical impedance tomography.
