“…The three roll milling approach can be applied at room temperature taking advantage of the contribution of the high viscosity to improve the dispersion of the nanofiller due to the higher level of the shear and elongational stresses transferred by the rolls to the epoxy/CNTs system. In other similar works, sonication has been used to maximize the dispersion level of CNTs with very good results . In our work with RTM 6 sonication was tried with no success since the local heating generated by the sonicating tip was responsible of a premature start of the curing reaction.…”

Carbon fiber composite laminates have good electrical properties due to the performance of the fibers, but the composite anisotropy induces a quite lower conductivity through the thickness. In fact, in this direction the fiber bundles are separated by insulating epoxy matrix. In this work, CNTs (carbon nanotubes) with different geometries and functionalization have been added to an epoxy resin to improve the electrical performance. The nanofilled matrix has been used to produce carbon fiber (CF) composites for aerospace applications. Multiscale modeling was used to predict some important parameters such as percolation threshold and the model has been successfully verified with experimental results. The results reported show a good improvement of the electrical and mechanical properties both in the matrix and in the composites. In particular, in composites with the nanocomposite matrix, an improvement of one order of magnitude in the electrical conductivity through the laminate thickness has been achieved. POLYM.

“…Obtaining highly purified and uniform CNT batches is a major challenge that has a significant impact on their use for applications in polymer/CNT fiber composites. The variation in the CNT from batch-to-batch results in significant property variation [ 122 ], which ultimately leads to disparities in the properties of the subsequent composite materials [ 30 , 31 , 32 ].…”

“…Therefore, composites incorporating carbon nanotubes (CNT) have received a great deal of attention in both academia and industry for their potential replacement of carbon fibers in polymer-based reinforced materials. Several reviews have already focused on summarizing the property enhancement of polymers by CNT [ 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ]. CNT have been heralded as a game changer for producing next-generation high-performance materials that would trump the properties of current CFRPs.…”

Among the many potential applications of carbon nanotubes (CNT), its usage to strengthen polymers has been paid considerable attention due to the exceptional stiffness, excellent strength, and the low density of CNT. This has provided numerous opportunities for the invention of new material systems for applications requiring high strength and high modulus. Precise control over processing factors, including preserving intact CNT structure, uniform dispersion of CNT within the polymer matrix, effective filler–matrix interfacial interactions, and alignment/orientation of polymer chains/CNT, contribute to the composite fibers’ superior properties. For this reason, fabrication methods play an important role in determining the composite fibers’ microstructure and ultimate mechanical behavior. The current state-of-the-art polymer/CNT high-performance composite fibers, especially in regards to processing–structure–performance, are reviewed in this contribution. Future needs for material by design approaches for processing these nano-composite systems are also discussed.

“…In addition, the rapid automation and digitization in manufacturing especially of transformative composite material or smart structures requires epoxy resins to exhibit hybrid properties. 11 Highly desirable in aviation, automotive and rail vehicles, and shipbuilding industries, is an epoxy resin of higher toughness yet is flexible and moldable; and in some of the automated processes rapid curing is essential. 12,13 Fabrication of structural parts that are nearly or intended to be exposed in extreme physical and chemical conditions such as in automotive engines and rockets mandates an epoxy matrix of high temperature and chemical stability.…”

Epoxy resin will continue to be in the forefront of many thermoset applications due to its versatile properties. However, with advancement in manufacturing, changing societal outlook for the chemical industries and emerging technologies that disrupt conventional approaches to thermoset fabrication, there is a need for a multifunctional epoxy resin that is able to adapt to newer and robust requirements. Epoxy resins that behave both like a thermoplastic and a thermoset resin with better properties are now the norm in research and development. In this paper, we viewed multifunctionality in epoxy resins in terms of other desirable properties such as its toughness and flexibility, rapid curing potential, self-healing ability, reprocessability and recyclability, high temperature stability and conductivity, which other authors failed to recognize. These aspects, when considered in the synthesis and formulation of epoxy resins will be a radical advance for thermosetting polymers, with a lot of applications. Therefore, we present an overview of the recent finding as to pave the way for varied approaches towards multifunctional epoxy resins.
