Filler materials are the inert materials which are used in glass fiber reinforced polymer (GFRP) composites for modifying the chemical and physical properties of the matrix polymers to reduce material costs, to improve processability, to improve product performance or to simply act as extenders or matrix diluents. Some of the commonly used fillers are carbon black, calcium carbonate, clay, alumina tri-hydrate, magnesium hydroxide, bone powder, coconut powder, hematite powder, TiO2, SiO2,ZnS, graphite, etc. Effect of these fillers on mechanical properties like tensile strength, flexural strength, inter laminar shear strength (ILSS), tensile modulus, impact strength, hardness were tested by various methods experimentally. Some of the authors also discussed the effect of filler size on the above mechanical properties.
