The Department of Metallurgy, Faculty of Engineering and the Built Environment, cordially invites you to a webinar entitled: “”Ultra-tough and in-situ repairable FRP composites” by Dr Everson Kandare (Australia)

Abstract

[In this presentation, Dr. Everson Kandare will unveil an experimental study exploring a novel concept of co-braiding engineering carbon fibres tows with mendable thermoplastic polymer filaments, resulting in through-the-thickness toughened composite laminates with in-situ delamination damage repair capabilities. The influence of intra-ply integrated poly[ethylene-co-(methacrylic acid)] (EMAA) filaments on the interlaminar fracture toughness of carbon fibre/epoxy laminates was assessed using the Mode I double cantilever beam methodology. Additionally, the impact of pre-forming on fracture initiation and crack growth resistance was investigated. Findings indicate that the laminate pre-formed for 1 minute exhibited the highest fracture toughness properties. While longer pre-forming times did not lead to further improvements to interlaminar fracture toughness, composites with a 3D fused EMAA network revealed effective delivery of the healing agent into delamination cracks, resulting in over 100% recovery in steady-state fracture toughness following delamination crack repair.]
