Micromechanical characterization of Carbon Black reinforced adhesive nanocomposite using micro indentation

Abstract : Carbon black (CB) reinforced adhesive are structurally complex materials with unique characteristics at various length scales. They have enormous potential applications in a variety of industries, automotive, aerospace, and marine. Microindentation with a VICKERS indenter was used to measure the micromechanical properties of carbon black CB reinforced adhesive composites with varying mass fractions (0, 1, 2, and 5 wt%). The micro-indentation deformation was studied by in-situ imaging of the impression using light microscopy analysis KEYENCE. Micromechanical properties, such as hardness, elastic modulus, and stiffness, gradually increase as the mass fraction of nanofiller (CB) continuously increases. This progress depends on various parameters, such as dispersion of nanofiller belong the adhesive matrix, interfacial bonding, and load transfer. These findings emphasize the possibility of achieving a diverse set of mechanical properties through a deeper understanding of the microindentation response of CB reinforced adhesive, which can be effective for the choice of materials and product developments in a variety of functional uses.
