## Description

- description: 'Advances have focused on disulfide-based epoxy-covalent adaptable
    network (CAN) polymer systems, which leverage reversible disulfide exchange reactions.
    The evolution from conventional carbon fiber reinforced thermosetting composites
    (CFRPs) to disulfide-based epoxy-CAN polymer composites represents a paradigm
    shift toward sustainable, high-performance materials. Recently, Teijin Ltd. has
    developed disulfide-based epoxy-CAN CFRP (carbon fiber: IMS65; resin: DGEBA/4-APD/PES5003P
    (disulfide-based epoxy-CAN polymer)). In this study, the mode-I and mode-II interlaminar
    fracture properties of the disulfide-based epoxy-CAN CFRP were investigated. The
    mode-I and mode-II interlaminar fracture tests were conducted under static loading
    using a double cantilever beam and end notched flexure specimens. The values of
    the mode-I and mode-II interlaminar fracture toughness of the disulfide-based
    epoxy-CAN CFRP were 0.293 and 1.054 kN/m, which were higher than those of conventional
    epoxy CFRP. The fracture surfaces of the disulfide-based epoxy-CAN CFRP were rougher
    than those of conventional epoxy CFRP. These improvements are attributed to enhanced
    fiber bridging, plastic deformation, and the dynamic disulfide exchange mechanism,
    which promote energy dissipation and interfacial adhesion. Compared to conventional
    epoxy CFRPs, the novel composite exhibits superior delamination resistance, recyclability,
    and potential for self-healing.'
