“…However it is important to study how the use of CNT webs may affect the ILFT of thin-ply laminates because, by combining these two non-conventional reinforcements, new opportunities may arise, and risks identified, in the development of multifunctional composite structures [10].…”

“…A combination of the conventional CF ply, thin CF ply and CNT web in an epoxy matrix offers the potential to create a truly hierarchical composite structure which optimises the advantages of each component, introduces additional through-thickness characteristics such as thermal and electrical conductivity and mitigates any weaknesses [13]. Such flexibility also underpins the development of additional functionalities such as structural health monitoring, anti-icing/de-icing and lightning strike protection within the composite structure [10].…”

Pristine and functionalized carbon nanotube (CNT) webs were introduced at the interlaminar region of two different thin-ply carbon fibre reinforced polymer systems (NTPT 402 prepreg, and TeXtreme/SE84LV). The Mode I interlaminar fracture toughness (ILFT) for the NTPT 402 material was substantially lower. In contrast when SE84LV resin was used, the resistance curves were virtually unchanged and with no depreciation in the steady state value of the ILFT. This demonstrates that a careful choice of the resin is essential to permit the embedding of CNT webs in thin-ply laminates without compromising structural performance and opens a new way towards the development of multifunctional thin-ply structures.

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.

“…A significant increment in the electrical conductivity and a decrement in electrical anisotropy was observed for both the material systems investigated. [2] Mohamad Fotouhi et al did study which exploits the potential of thin-ply carbon/glass hybrid laminates to generate high performance Quasi-Isotropic (QI) composite plates that show pseudo-ductility in all fibre orientations under tensile loading, overcoming the inherent brittleness of conventional composites. Two types of QI lay-ups with 45 and 60 intervals, i.e.…”

Synthetic composites have higher strength to weight ratio and are extensively used in industrial applications. Most of the composites have orthotropic properties and their strength varies as per orientation. Carbon fibers are one of the synthetic fibres having extensively high tensile strength. Laminates having different ply orientations have different properties and strengths. Hence, to enhance strength properties, reducing layerwise damage becomes of up most important. It is not possible to investigate the layerwise damage of each ply separately by experimentation. This can be done by using ACP tool in ANSYS 19.2 software. In this project, two laminates having orientations as 0°-45°-0° and 0°-30°-60° are considered for analysis. Advance composite pre-post [ACP] tool from ANSYS software is used for simulation of these layers. From this analysis total deformation, equivalent stress and damage of each layer is determined. After getting layerwise damage, experimentation is done. Experimental tensile test is done on specimens above ply orientations to obtain force vs. deflection diagrams. Comparative analysis is made between simulation and experimental results. Results and conclusion is drawn. Experimental and simulation values differ by only 1%. This validates the simulation value of force reaction. Also from the result it can be seen that 0°-45°-0° laminate gives better results than that of 0°-30°-60° laminate. Hence, it can be concluded that Plate 1 has higher strength than Plate 2 i.e., 0°-45°-0° is better ply orientation than 0°-30°-60° ply orientation. Also it is observed that different ply orientations have different strengths.
