Çeşitli Matris Malzemelerinin Bazalt/Jüt/Cam Elyaf Takviyeli Hibrit Kompozitlerin Mekanik Özelliklerine Etkisi

Abstract

In this research, the effect of different matrix materials (epoxy and vinylester) on the mechanical properties of Basalt, Jute, and Glass fiber-based hybrid composites were analyzed mechanically and morphologically. The mechanical test results were achieved by the Tensile test and Vickers hardness test, while morphologic images were obtained by Scanning Electron Microscopy. Basalt fiber fabric, Jute fiber fabric, and Glass fiber fabrics of 86 gr/m² and 100 gr/m² were used as reinforcement elements, while epoxy and vinylester were utilized as matrix materials. A vacuum assisted resin transfer molding method was used as the production technique. In the results, it is given how the use of different reinforcement element types and different matrix materials affects the mechanical properties of the produced composite samples. Results show that the tensile strength of basalt fiber/glass fiber (100 gr/m²) reinforced with epoxy is the highest in all of the produced composites. In terms of microhardness, the hardness value of basalt fiber/glass fiber (100 gr/m²) reinforced epoxy composites have 1.39 times higher than basalt/glass fiber (100 gr/m²) reinforced vinylester composites. Scanning electron microscopy (SEM) analysis was utilized to examine the fiber rupture and fracture mode in hybrid composites. As a result of the analysis, also it was observed SEM results support the mechanical test results.
