Evaluation of Mechanical Properties of GFRP Composites with Fillers

The usage of GFRP composites are gradually increasing day by day because of its unique properties over conventional metals. GFRP composite materials are much stronger and contain less weight than the metals which are using in more industries like Automobiles. And it was noticed that the properties of the GFRP composites are decreasing noticeably in certain environmental conditions. So, it is important to improve the quality and mechanical properties of the GFRP composites that they use to odder environmental conditions. From the farmer literature it was observed that adding filler materials to the composite adhesive can enhance the strength and properties of the composite material. In this investigation two filler materials (Znso4, talc) are added to the composites in certain ratios (1%,3%,5% and 7%). And to observe the mechanical properties specimens are placed in water for 30 days, and mechanical tests were performed on the specimens. And It was observed when fillers are added to the matrix of the composite the mechanical properties are increased when it compares to the no filler added composites. Properties are enhanced when the certain ratio of filler were added. Again properties are decreased when the high amount of fillers were added. And high tensile properties were observed when the 3% of filler added. And flexural properties and ILSS properties are enhanced when 1% of filler added.
