This study looked at how adding SiO2 nanofillers to a nanocomposite made from basalt and epoxy laminate changed its mechanical, wear, and toughness properties. With the hand layup method, laminates were made by adding different amounts of SiO2 nanofillers to composites made of epoxy and basalt. Mechanical characteristics, such as hardness and impact, were examined following ASTM specifications. Wear experiments were conducted, maintaining a constant sliding distance for various weights and sliding velocities. The results demonstrated, that as the proportion of nanofillers increased, the impact and hardness qualities also increased. The composite with 2.5 weight percent of nanofillers exhibited the highest hardness at 27.52 HV, surpassing empty materials by more than 19%. A material containing 1.5 weight percent nanofillers demonstrated an impact strength of 168.21 MJ/m², representing a 29% increase, compared to the impact toughness of empty materials. Based on the wear data, adding SiO2 nanofillers greatly lowered the loss by wear in the basalt/epoxy composite. Scanning electron microscopy (SEM) pictures were employed to analyse deteriorated and fragmented surfaces, with the outcomes showing good agreement with these findings. [ABSTRACT FROM AUTHOR] |
