摘要: This study focuses on the transfer of healing functionality supramolecular polymers (SP) to fibre reinforced composites through interleaving. SPs exhibiting self-healing based hydrogen bonds were formed into films and successfully incorporated carbon composites. The effect SP interleaves in-plane fracture toughness subsequent capability hybrid investigated under mode II loading. showed considerable increase since maximum load (P max ) composite approximately doubled, consequently interlaminar energy (G IIC exhibited an reaching nearly 100% compared reference composite. component was activated using external heat. P G recovery after activation measured, a efficiency first cycle close 85% for , eventually dropping 80% while retained around even fourth cycle. Acoustic Emission activity during tests monitored found be strongly reduced due presence SP.
