AB  - Fiber-reinforced polymer composites as a structural material have garnered 
      tremendous interest over the past few decades. In particular, carbon 
      fiber-reinforced epoxy (CFRE) laminates have seen extensive use in the aircraft 
      and aerospace industry. The role of the interface between the matrix and fiber is 
      critical and dictates the overall structural properties of the CFRE laminate. 
      Herein, we attempt to use a commercially viable, green, and facile approach, 
      electrophoretic deposition (EPD), to deposit covalently coupled multiscale 
      graphene oxide (GO)/carbon nanotube (CNT) nanoconstructs onto carbon fiber (CF) 
      fabric. The rationale behind using these hybrid conjugates is to exploit the 
      positive synergistic effect of combining two-dimensional (2D) GO and 
      one-dimensional (1D) CNT nanoparticles, which provide strengthening through 
      different mechanisms resulting in a stronger matrix/fiber interface. The modified 
      laminate with just 0.1 wt % GO/CNT content exhibited an improvement in flexural 
      strength (FS) by 24% and interlaminar shear strength (ILSS) by 30% compared to 
      the neat CFRE. Scanning electron microscope (SEM) micrographs confirmed uniform 
      and homogeneous GO and GO/CNT deposition on CF. Raman, Fourier-transform infrared 
      spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS) analyses validate 
      the successful functionalization of CNT and covalent coupling of GO and CNT. 
      Atomic force microscope (AFM) and contact angle analyses indicate improved 
      interaction between the CF and matrix. The deposition of the GO/CNT nanoconstruct 
      on the CF improved the performance of CFREs owing to enhanced wettability, 
      surface free energy, and surface roughness, leading to increased mechanical 
      interlocking between the epoxy and CF at the interface. Dynamic mechanical 
      analysis showed decreased segmental motion of epoxy chains due to improved 
      interfacial adhesion following modification. Interesting observations were made 
      in SEM fractography, which showed considerably different failure mechanisms in 
      the modified CFREs. Electromagnetic interference (EMI) shielding effectiveness of 
      -45 dB was achieved in the case of the GO/CNT-CFRE system. Electrothermal heating 
      and de-icing performance of the modified system were also explored in this study. 
      This versatile approach can open up new avenues for CFRE modification leading to 
      considerably improved performance.
