Abstract
In this work, unsaturated polyester, resin, matrix reinforced, with fiberglass mat chopped were developed using TiO₂ and SiO₂ Nanoparticles as filler materials. The individual and combined eﬀects of nanoparticles on the nanocomposite and material properties were examined. An improvement in Young’s modulus (39,3%) using combined weight of TiO₂+ SiO₂ was observed to be 3%. Examined nanoparticles have shown normal distribution in grain size indicated to be within standard limit, therefore boosting nanocomposite material to have excellent hardness, roughness, impact, and flexural resistance. DSC was characterized by transitions in this material. SEM and EDS techniques were used to confirm the formation of TiO₂ and SiO₂. The nanocomposites can be used in light-shielding, applications as well as in the industrial sectors.
Highlights
The tensile test revealed that the latest mix has the better modulus of elasticity at (3% wt). This nanocomposite material showed very good roughness, hardness, flexural, and impact resistance. The good dispersion of the nanoparticles had a great role in having this material good properties as aggregation may lead to a decrease in the quality of the properties.
