“…The hardness and tensile strength are found to increase by 2.65 times the primary glass with the addition of 0.4 weight% of CNPs. This increase may be attributed to the introduction of strong covalent C-C bonds in the glass network with the inclusion of CNPs [24][25][26]. Similar values for hardness and tensile strengths were obtained at an applied load of 200 g.…”

Carbon nanoparticle (CNP)-lithium borate glass composites are synthesised by melt-quenching technique to study the influence of CNPs addition on the mechanical properties of the primary glass. Three different glass composites are fabricated by varying the weight% of CNPs. The hardness and tensile strength are found to increase by 2.65 times the primary glass with the addition of 0.4 weight% of CNPs. The homogeneous dispersion and close-packing of nanoparticles achieved in the resultant glass matrix account for this improvement. The closed-packed structure reduces the free volume between molecules, thereby limiting their movement and enhancing interfacial bonding. The formation of such a cross-linked structure with the addition of CNPs is supported by density measurements, electron microscopy images, and glass transition temperature studies.

“…This can be attributed to the 3-D structure of carbon foam and the formation of its percolation network. The formation of the percolation network provides a path for phonons in thermal conduction and prevents phonon scattering via defects in the composites [30].…”

a b s t r a c tZrO 2 -based composites reinforced with 6.5 vol.% of carbon foam, carbon fiber, and graphite were fabricated using spark plasma sintering, and characterized using scanning electron microscopy and X-ray diffractometry. Their thermal properties were also investigated. The microstructures of the reinforced composites showed that carbon fiber fully reacted with ZrO 2 , whereas carbon foam and graphite did not. The carbothermal reaction of carbon fiber had a negative effect on the thermal properties of the reinforced ZrO 2 composites because of the formation of zirconium oxycarbide. Meanwhile, the addition of carbon foam had a positive effect, increasing the thermal conductivity from 2.86 to 3.38 W m À1 K À1 at 1,100 C.These findings suggest that the homogenous distribution and chemical stability of reinforcement material affect the thermal properties of ZrO 2 -based composites.
