High crack self-healing efficiency and enhanced free-edge delamination resistance of carbon fibrous composites with hierarchical interleaves

High crack self-healing efficiency and enhanced free-edge delamination resistance of carbon fibrous composites with hierarchical interleaves

Carbon nanotube (CNT), poly(ethylene-co-methacrylic acid) (EMAA) and epoxy (EP) are used to prepare a hierarchical interleaf, consisting of [CNT/EP/EMAA]s sandwich structure with periodic EP column arrays, which can act as crack self-healing interface within carbon fiber reinforced plastic (CFRP) by...

Zusammenfassung:Carbon nanotube (CNT), poly(ethylene-co-methacrylic acid) (EMAA) and epoxy (EP) are used to prepare a hierarchical interleaf, consisting of [CNT/EP/EMAA]s sandwich structure with periodic EP column arrays, which can act as crack self-healing interface within carbon fiber reinforced plastic (CFRP) by in-situ electrical-heating the CNTs. Results show that the introduced [CNT/EP/EMAA]s interleaf has little effect on the free-edge delamination initiation stress (
