“…poxy resins are a class of thermosetting polymers frequently used as matrices in polymeric composites due to their interesting characteristics, such as dimensional stability, chemical resistance, good stiffness, high specific strength and good adhesion to various types of reinforcements [1,2]. Epoxy resin is a thermostable polymer consisted of two principal parts: resin and hardener.…”

Epoxy with carbon nanofibers (CNFs) are effective nano enhanced materials that can be prepared by easy and low-cost method. The present paper compares the improvements, in terms of flexural and viscoelastic properties, of two epoxy resins reinforced with different weight percentages (wt.%) of CNFs. These epoxy resins have different viscosities, and weight contents between 0% and 1% of CNFs were used to achieve the maximum mechanical properties. Subsequently, for the best configurations obtained, the sensitivity to the strain rate and the viscoelastic behaviour (stress relaxation and creep) were analysed based on international standards. It was possible to conclude that, for both resins, carbon CNFs promote significant improvements in all the studied mechanical properties, even for different contents by weight.

“…Microhardness rapidly increased as the MCN of the SSS ChGs approached 2.4, signifying the transition of the SSS glass network from under-cross-linked floppy to over-constrained rigid state. Kancherla et al [152] studied the mechanical properties of glass fabric composite with surfactant treated zirconia nanoparticles. The optimal dispersion of yttria stabilized zirconia (YSZ) nanoparticles in matrix-fabric system was carried out.…”

The thrust to invent new materials and technology has been ever increasing due to technological challenges in progressive world. Among new materials, nanomaterials possess superior optical, electrical, magnetic, mechanical, and thermal properties, which have made them suitable for a multitude of applications. The present review paper deals with recent advances in properties of nanostructured glasses and composites in terms optical, electrical, mechanical and thermal properties. A brief discussion has been done on fabrication method of nanostructured glasses. The review of optical properties shows that nanostructured glasses show both direct and indirect band gap and this tuning of band gap depends on extent of nano structuring of samples. The electrical properties also show enhancement in electrical conductivity on nano-structuring of glasses compared to their bulk counterparts. The changes in mechanical and thermal properties of nanostructured glasses and composites are attributed to many microstructural features like grain size and shape, their distribution, pores and their distribution, other flaws/defects and their distribution, surface condition, impurity level, second phases/dopants, stress, duration of its application and temperature effect on the samples. Literature reports that nano structuring leads to enhanced phonon boundary scattering which reduces the thermal conductivity.

“…Mechanical properties were observed to be enhanced. Surfactant-treated zirconia nanoparticles were used by Kancherla et al 122 for enhancing the mechanical properties of GFRP. Specific strength and modulus (compressive, tensile, flexural) were observed to be enhanced at 3 wt % nanoparticle dispersion in the epoxy matrix.…”

Research and development in the field of structural composites have explored various combinations of materials and methods to fulfill the load-bearing demands of industries such as automotive, aerospace, military, civil, and construction. Continuous fiber-reinforced composites based on epoxy are extensively used for primary load-bearing structural applications, owing to their unique characteristics and abilities compared to their counterparts with other polymers, thermosets in particular. With the introduction of nanotechnology and the resultant development of a new class of materials called nanomaterials, it has been observed that various properties of composites can be enhanced by the incorporation of these materials into composites. Different nanofiller materials have different effects on composite properties. This review focuses on a survey of literature published over the last two decades in which nanofillers were utilized to enhance the structural properties of epoxy-based fiber-reinforced composites. Composite modifications using carbon-based nanomaterials (fullerenes, carbon nanotubes, carbon nanofibers, graphene nanoplatelets, graphene oxide), nanosilica, nanoclay, etc. are discussed in detail. A brief summary of the use of a combination of nanofillers and attempts on the modification of reinforcement fabric is also presented.
