Carbon nanotube integrated textile structural composites are one of the demanded materials especially for space/aerospace and defense industries in the 21st century due to their better damage tolerance properties compared to the metal and ceramics. This review paper exclusively performed on carbon nanotubes (CNTs) added carbon fiber/epoxy multiscale composites, including recent innovative methods of integrating CNTs to carbon filaments using the direct method such as growing on fiber, chemical grafting, and nanostitching or indirect methods such as mixing with matrix and application via lay-up and dip coating. In addition, various composite fabrication techniques, including vacuum bag molding, resin transfer molding, and resin film infusion molding techniques were discussed. Critical thermo-mechanical and electrical properties considering numerous micromechanics based composite modeling and computational analysis were explained. The review concludes that CNTs added carbon fiber/epoxy multiscale composites possess considerable potential in the use of advanced nanocomposites applications.

“…[1][2][3][4][5][6] The integration of carbon fillers into a neat polymer matrix provides superior properties due to the synergic effect by combining the characteristics of the matrix and the carbon fillers. Recently, numerous studies have been devoted to the structural and physical properties of the polymer composites including various forms of carbon, such as carbon nanotubes (CNTs), [7][8][9][10][11] graphene, [12][13][14] fullerene, [15,16] carbon black, [3,17,18] graphite, [4,19] etc., which are different in the size, geometry, and physical properties. Based on the chemical, thermal, and mechanical properties, epoxy is a thermosetting polymer that has been widely used in various applications owing to its outstanding adhesion strength, high heat and electrical resistance, easy fabrication, and low cost.…”

Herein, we present a simple procedure for fabricating epoxy/graphite composites using a simple solution blending method. The addition of graphite filler in the epoxy matrix showed a beneficial effect on mechanical properties by enhancing Young's modulus up to 55.25% of its value. The highest thermal conductivity was obtained to be 1.53 ± 0.07 W· m−1· K−1, which depicts a fourfold increment as compared to the neat matrix. The effective thermal conductivity has been predicted using Nan model, which shows a satisfactory agreement with the experimental data. Besides, the investigated composites display enhanced electrical conductivity; this evolution of electrical conductivity as a function of filler volume fraction is well described using percolation theory. Thermogravimetry and differential scanning calorimetry have been used to determine the thermal properties of the composites as a function of filler volume fraction. These findings indicate that the thermal, electrical, and mechanical properties of epoxy/graphite composites could be ideal for thermal management and control of heat transfer devices.

“…AHM was used to derive the antiplane efficient characteristics of three-phase MEE materials (Espinosa-Almeyda et al, 2014). The two-scale AHM was adopted to determine the efficient stiffness of composite structures (Jeong et al, 2019). AHM can be used to obtain a reliable solution to nanostructures (Tahani and Safarian, 2019).…”

The node-based smoothed radial point interpolation method combined with the asymptotic homogenization method was proposed, as an addition to the finite element method, to address the static and dynamic reactions of magneto-electro-elastic coupling micromechanical problems. First, several basic equations for relevant problems were derived. Second, asymptotic homogenization method was utilized to determine the material properties of magneto-electro-elastic nanomaterials. Third, node-based smoothed radial point interpolation method was applied to obtain the discrete equations of magneto-electro-elastic nanostructures. Then, the Newmark method was introduced to solve the response of microcosmic problems. Finally, several numerical examples were calculated to prove the accuracy, convergence, and reliability of node-based smoothed radial point interpolation method by comparing the results of node-based smoothed radial point interpolation method with those of finite element method.
