In this study, compression molding was used to produce elastomeric nanocomposite foams based on natural rubber (NR) with a hybrid reinforcing system containing organo-modified nanoscale (NC) and nanocarbon black (NCB). The effect of NC content (0-10 part per hundred rubber, phr) on the curing behavior, as well as the morphological and mechanical properties of elastomeric foams containing 10 phr of NCB was determined. Transmission electron microscopy and X-ray diffraction results showed that NC exfoliation occurred at low NC concentration (less than 5 phr), while increasing NC content up to 5 phr led to aggregation. Rheological data revealed that increasing the NC content up to 10 phr gradually changed the curing parameters such as 50% shorter scorch and curing time, two times faster curing rate, as well as higher initial (35%) and final (35%) torque. Scanning electron microscopy analysis also showed that increasing NC content from 0 to 5 phr produced foams with more uniform small cells, while 7 phr of NC changed the foam structure into two areas composed of different cell sizes and different cell densities. Higher NC content (10 phr) led to broken cell walls. With nanoparticles, higher foam modulus (83%) and hardness (104%) were observed. Finally, NC addition was found to improve the NR's thermal and thermooxidative resistance while the sound absorption coefficient was constant.

“…Silica aerogel is a promising candidate for improving the mechanical properties of epoxy‐based nanocomposites because of the unique properties such as the three‐dimensional nanoporous structure and high surface area . High specific mechanical properties and multifunctional characteristics of the aerogel/polymer nanocomposites make them desirable in various applications such as energy dissipating/absorbing, thermal and acoustical insulation, flame retardancy, and so forth …”

Composite materials are increasingly being used as an accepted alternative to traditional structural materials throughout the globe for various engineering applications. Because of their superior properties and flexibility, these materials are beginning to find innumerable applications replacing existing materials, especially in high‐performance engineering domains. The electrospinning process adds a further dimension to enhance the properties of the composite material family by incorporating fibers at their microscale to even sub‐nanoscale, enabling the development of advanced composites with enhanced properties. Over the past decades, much research work has understandably been done on these exciting materials. This paper aims to comprehensively map some of the trends in electrospun nanofiber interleaved laminated composite development, marking the milestones achieved and challenges faced. A brief review of the potential applications for these materials will also be put forward in the research outlook for these advanced nanoengineered composites.

There has been a steady progress in developing synthetic fibers in the past few years. Bicomponent fibers and nanofibers in a core/shell (C/S) configuration, including two dissimilar materials have presented unusual potential for use in many novel applications. These fibers can be produced using a variety of materials via different techniques i.e., coaxial melt spinning and electrospinning. In this review, we discuss the recent advances in C/S fibers and nanofibers' production. The first part has been assigned to the bicomponent fibers manufacturing technology, while production and applications of C/S nanofibers have been described in the second part.
