This study investigates the thermal and mechanical properties of an innovative polymer composite reinforced with basalt fiber and lead oxide nanoparticles , tailored for energy storage applications . The composite was synthesized by incorporating basalt fiber and varying concentrations (3 to 15 g) of lead oxide nanoparticles into an epoxy resin matrix . Mechanical testing revealed significant improvements in tensile, compressive, flexural, and impact strength , with increases of 11 %, 8 %, 10 %, and 30 %, respectively. Scanning electron microscopic analysis confirmed a uniform dispersion of lead oxide nanoparticles and strong interfacial bonding between the basalt fibers and the epoxy matrix . The viscoelastic analysis showed a notable enhancement in storage modulus , rising from 2650 MPa to 2980 MPa for composites containing 3 to 12 g of lead oxide nanoparticles. Thermogravimetric analysis indicated improved thermal stability, with the decomposition temperature increasing from 350 °C for pure epoxy to 410 °C for the composite with 12 g of lead oxide nanoparticles. Furthermore, the composite demonstrated improved thermal conductivity , reaching 0.34 W/mK, enhancing its heat dissipation capacity. These results highlight the potential of this novel composite material for advanced energy storage systems , offering superior mechanical strength , enhanced thermal stability, and improved heat dissipation, making it a potential material for high-performance energy applications .
