A STUDY ON EFFECT OF FILLER (SIO2) ON MECHANICAL PROPERTIES OF GLASS/EPOXY (HT CURE) COMPOSITE

Abstract

Glass fiber reinforced epoxy based composites(GFREC) are mostly widely used as structural material in engineering applications such as aerospace , automotive ,ship building , sports and chemical industries , etc. because of their tailor made properties. The mechanical properties of glass fiber reinforced composite materials are different for different constituents. GFREC materials are in anisotropic nature. In the present investigation fiber polymer glass epoxy composites are reinforced with silicon dioxide(í µí± í µí±–í µí±œ 2)as filler in different weight fractions are fabricated and cured in auto clave process (HT cure). The fabricated laminates are tested according to ASTM standards to determine physical properties, barcol hardness, flexural strength, and inter laminar shear strength (ILSS).From the experimental results obtained, it shows that the mechanical properties were enhanced when the percentage of silicon dioxide(í µí± í µí±–í µí±œ 2) was increased
