Abstract
(EN) A self-healable composite material is provided. The self-healable composite material comprises: nanofibers for healing comprising a healing agent core containing a healing agent and a shell for healing enclosing the healing agent core; nanofibers for curing comprising a curing agent core containing a curing agent and a shell for curing enclosing the curing agent core; and a composite containing the nanofibers for healing and the nanofibers for curing. The shell for healing and the shell for curing contain a substance in which polyvinylidene fluoride and thermoplastic starch are linked by a cross-linking agent.
(FR) L'invention concerne un matériau composite auto-réparable. Le matériau composite auto-réparable comprend : des nanofibres pour la réparation comprenant un noyau d'agent de réparation contenant un agent de réparation et une enveloppe pour la réparation entourant le noyau d'agent de réparation; des nanofibres pour le durcissement comprenant un noyau d'agent de durcissement contenant un agent de durcissement et une enveloppe pour le durcissement renfermant le noyau d'agent de durcissement; et un composite contenant les nanofibres pour la réparation et les nanofibres pour le durcissement. L'enveloppe pour la réparation et l'enveloppe pour le durcissement contiennent une substance dans laquelle du fluorure de polyvinylidène et de l'amidon thermoplastique sont liés par un agent de réticulation.
