Engineering the electrospinning of MWCNTs/epoxy nanofiber scaffolds to enhance physical and mechanical properties of CFRPs

A cost-effective approach to improve the physical and mechanical properties of carbon fiber reinforced polymer (CFRP) prepreg composites, where electrospun multiwalled nanotubes (MWCNTs)/epoxy nanofibers were synthesized incorporated in between layers conventional CFRP composite has been presented. MWCNT-aligned epoxy successfully produced by an optimized electrospinning process. Nanofibers deposited directly onto achieve improved adhesion interfacial bonding, leading added strength improvements other properties. Thus, interlaminar shear (ILSS) fatigue performance at high-stress regimes increased 29% 27%, respectively. Barely visible impact damage (BVID) energy significantly up 45%. The thermal electrical conductivities also enhanced due presence highly conductive MWCNT networks layers. presented method was capable uniformly depositing high contents MWCNTs ply interface prepregs strengthen/enhance properties, which not previously shown be possible resin viscosity caused randomly oriented system.
