Carbon fiber reinforced composites have been widely studied due to their potential applications in various fields. However, the weak interface performance between the fiber and resin limits the overall properties of the composites. This review emphasizes the importance of introducing a third phase monomer, such as carbon nanotubes or graphene, to modify the interface structure. The effects of these nanomaterials on the fiber/resin interface and the relationship between the multi-scale interface structure and properties have been investigated. Various theories, such as transition layer, chemical bonding, mechanical interlocking, infiltration, diffusion, and adsorption, have been employed to improve the interface properties. Overall, this work provides valuable insights for the preparation of carbon fiber reinforced composites with enhanced interlaminar shear strength.
Carbon fiber reinforced composites have attracted lots of attention in many fields. However, on account of the poor infiltration of resin to carbon fiber, the weak interface performance between fiber and resin has been restricting the interface properties of composites. In recent progress, the review attaches more importance to the introduction of the third phase monomer, which mainly uses physical and chemical methods to assemble nanomaterials (such as carbon nanotubes, graphene, etc.) on the carbon fiber surface to modify the interface structure of the carbon fiber reinforced composites, and all of them have been demonstrated in this paper. Furthermore, the effects of introducing nanomaterials on the structure of the fiber/resin interface and the relationship between multi-scale interface structure and properties have been investigated. It can be seen that the design idea of researchers mainly uses one or more theories to improve the interface properties of carbon fiber reinforced composites, such as transition layer, chemical bonding, mechanical interlocking, infiltration, diffusion, and adsorption. In brief, this work provides some novel insights for the preparation of carbon fiber reinforced composites with excellent interlaminar shear strength.
