“…In recent decade, many methods to improve the interfacial adhesion of fibrous composites have been proposed, such as chemical grafting, [4,12,13] sizing, [7,14,15] growing carbon black, [10,16,17] electrophoretic deposition, [18][19][20] and introducing nanoparticles. [21][22][23][24][25] But some of them are carried out at extremely toxic, high-energy consuming and harsh conditions, which have a limited development in industrial applications. Moreover, the worldwide critical need for environmental-friendly and sustainable approach has been increasing.…”

To improve interfacial adhesion between carbon fiber (CF) and epoxy resin, a low‐cost and environment‐friendly method was developed to treat the CF surface via the bio‐inspired co‐deposition of catechol (Cc) and polyethyleneimine (PEI). It is noteworthy that the deposition process reacts at room temperature with water as solvent, and does not require harsh conditions or the use of toxic reagents. After treatment, the CF/epoxy composites were endowed with excellent mechanical properties and showed increases of 51.9% and 51.7% for flexural strength and ILSS, respectively, in comparison with unsized CF laminates. The analyses of fractured surface morphologies and strengthening mechanism of the composites indicated that the uniformly coated Cc‐PEI on the fiber surface can promote the diffusion and entanglement of the matrix molecular chains and form chemical bonding as well as π‐π stacking, thus effectively improving the interfacial adhesion. In addition, the facile process disclosed in this study can provide a new strategy to not only for CF treating but also expected to be used in the modification of other high performance fiber reinforcement and industrial applications.

“…Moreover, CNTs already attract a lot of attention as promising materials in various fields such as sensors [12], energy applications [13], biomedical applications [14], polymer composites [15,16]. Successful attempt to exploit mechanical properties of CNT has been demonstrated enormously in the case of CNT reinforced polymer composites with improved tensile strength [17], flexural strength [18] and fatigue resistance [19,20]. This has led to the experimentation of reinforcing metals (polycrystalline and Nanocrystalline) with CNTs, thereby producing "Metal Matrix Composites" (MMCs), a new class of composites to achieve a combination of enhanced strength and ductility [21,22].…”

Molecular dynamics (MD) based study of nanocrystalline (NC) Al and CNT (carbon nanotube) reinforced NC Al specimens having grain sizes ~9 nm have been carried out under tensile loading using hybrid potentials for different temperatures (10 K, 300 K and 681 K) at a particular strain rate of 10 10 s-1. Structural variation and defect evolution during the deformation have been investigated. An enhancement in both strength and ductility is observed in case of the CNT embedded NC Al specimens with respect to NC Al specimen and such improvement is significant in case of (30,30) CNT embedded NC Al specimen. It is also found that NC Al matrix is fractured first, then the CNT at lower test temperature, whereas at high temperature, the CNT fractures before the matrix.

Surface treatment is typically required to improve the bonding performance of carbon-fiber-reinforced composites. Herein, a wet peel ply was prepared using bismaleimide (BMI) resins as a matrix resin. The temperature–heating rate extrapolation method and rheological method were employed to study the reaction characteristics and viscosity-temperature characteristics of the matrix in the BMI wet peel ply. The curing temperatures of the BMI wet peel ply and the BMI prepreg were the same (200 °C), making this wet peel ply suitable for co-curing with the BMI prepreg. After treatment with the wet peel ply, the bonding strength of the BMI composite joint showed a mean shear strength of 35.5 MPa, which was 1.72% higher than that of the sanded composite and 17.5% higher than that of the composite treated with the dry peel ply. In addition, the BMI composite treated with the BMI wet peel ply exhibited good bonding stability with a coefficient of variation of 3.9. After damp-heat aging for 1440 h, the retention rate of shear strength at room-temperature was 82.3%. The relatively loosely woven carrier in the BMI wet peel ply increased the surface roughness of the composite, thus improving the bonding strength.
