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.

“…Toughening a composite material is a common tactic for enhancing damage resistance. There has been much interest in inserting thermoplastic veils to improve interlaminar fracture toughness [ 10 , 11 , 12 , 13 ], especially since the commercialization of Xantulayr ® , a toughening veil made of electrospun nanofibres by Revolution Fibers [ 14 ]. Depending on the type of fibres, soluble or insoluble, thermoplastic veils can result in agglomerates when the dispersion is poor.…”

Experimental Study on the Interlaminar Fracture Properties of Carbon Fibre Reinforced Polymer Composites with a Single Embedded Toughened Film

et al. 2021

In this study, two types of single polymer films have been inserted in a composite laminate to examine their toughening effects on mechanical properties. The first is a thermoplastic polyurethane (PU) film, and the second is an adhesive epoxy film featuring a polyester net. The laminates were manufactured either using a co-curing (CC) process or a secondary bonding (SB) process used for the epoxy film. Mode I and mode II interlaminar fracture toughness were measured for laminates manufactured by both processes and compared with the corresponding reference laminate toughness. A significant increase in both mode I and mode II toughness resulted when introducing a single PU film, approximately 290% and 50%, respectively. Similarly, the epoxy film improved the interlaminar fracture properties; the CC process produced an increase of 175% for mode II toughness, while the SB adhesive film showed an increase of 75% for mode II toughness.

“…In these techniques, the nonwovens are made of concentrates that contain carbon nanotubes dispersed in a polymer matrix. Another approach is the production of nonwovens from neat polymers, followed by soaking them in a solution containing CNT, or spraying such a solution onto the surface of the nonwovens [ 25 , 26 , 27 ].…”

The main aim of this work was the investigation of the possibility of replacing the heavy metallic meshes applied onto the composite structure in airplanes for lightning strike protection with a thin film of Tuball single-wall carbon nanotubes in the form of ultra-light, conductive paper. The Tuball paper studied contained 75 wt% or 90 wt% of carbon nanotubes and was applied on the top of carbon fibre reinforced polymer before fabrication of flat panels. First, the electrical conductivity, impact resistance and thermo-mechanical properties of modified laminates were measured and compared with the reference values. Then, flat panels with selected Tuball paper, expanded copper foil and reference panels were fabricated for lightning strike tests. The effectiveness of lightning strike protection was evaluated by using the ultrasonic phased-array technique. It was found that the introduction of Tuball paper on the laminates surface improved both the surface and the volume electrical conductivity by 8800% and 300%, respectively. The impact resistance was tested in two directions, perpendicular and parallel to the carbon fibres, and the values increased by 9.8% and 44%, respectively. The dynamic thermo-mechanical analysis showed higher stiffness and a slight increase in glass transition temperature of the modified laminates. Ultrasonic investigation after lightning strike tests showed that the effectiveness of Tuball paper is comparable to expanded copper foil.
