▎ 摘　　要

In this work, novel graphene nanoplatelets (GnP)/silicon carbide nanowires (SiCnw) hybrid nanostructured films were successfully produced and employed as reinforcements for developing advanced laminated composites (CFRP). The one-dimensional continuous SiCnw uniformly interpenetrated within the hybrid films, which effectively connected and bridged adjacent GnP flakes, and facilitated heat flow across the interfacial boundaries in the through-thickness direction of the CFRP. The incorporation of GnP/SiCnw hybrids containing 5 wt% SiCnw significantly promoted the out-of-plane thermal conductivity of the CFRP, reaching 2.19 W/m center dot K, which represents increments of 186.3% and 54.2% compared to the neat CFRP and pure GnP film interleaved CFRP, respectively. Furthermore, the storage modulus and interlaminar shear strength of the CFRP were also evidently enhanced after introducing the GnP/SiCnw interleaves. This study proves the superiority of binary GnP/SiCnw films as reinforcements, and provides the guidance for the structural design of CFRP with excellent thermal and mechanical performances.
