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.

“…[1][2][3][4][5] For almost a couple of decades, scientists and researchers around the world have been pursuing with great interest the development of self-healable polymer and composites. [6][7][8][9][10][11] The first work reported by White et al 12 in this field involved the use of extrinsic elements in the bulk polymer, that is, capsules and a catalyst for the self-healing of cracks. Up to now, different approaches have been considered for the healing of bulk polymers and/or composites, and the repairing potential was evaluated by investigating the crack propagation resistance before and after the mending process.…”

Cyclic olefin copolymer (COC) is utilized as thermoplastic healing agent in an epoxy resin and the effect of mending temperature on the healing of resulting materials is investigated. Blends are prepared by adding 20 and 30 wt% COC powder in the epoxy resin. They are thermo-mechanically characterized and fractured samples are thermally mended at various temperatures to evaluate the healing efficiency of the repaired samples. Optical microscopy reveals a homogenous dispersion of COC domains within epoxy matrix, while thermogravimetric analysis shows improved thermal stability of the samples. The immiscibility of the two phases in the blends lead to a decrease of the mechanical properties under flexural and tensile loading modes with respect to neat epoxy. The fracture toughness increases upon COC addition at elevated amounts. Healing efficiency values up to more than 80% are obtained at the lowest investigated temperature of 145 C for samples with 30 wt% of COC.

Carbon nanotubes (CNTs) are an economical and multi‐functional nanofiller that can further elevate the versatile performance of fiber‐reinforced polymer (FRP). The past two decades have seen significant progress in the design, fabrication, and characterization of CNTs modified FRPs (CNT‐FRPs). The introduction of CNTs has been proven to enhance the key mechanical properties of CNT‐FRPs and endow the composite with additional functional properties. In this review, the fabrication routes of CNT incorporation into FRPs are first discussed, and then the critical effects of CNTs on various mechanical properties of CNT‐FRPs are described. Next, as a complement to the experimental results, modeling studies on CNT‐FRPs are included to reveal the underlying structural effects, followed by a discussion on the reinforcement and toughening mechanisms of CNT‐FRPs. The intent of this review is to provide a comprehensive summary on CNT modified FRP composites, and to shed light on the future research and development of CNT modified composites.
