| dc.description.abstract | The application of natural fibers could be enhanced by using them together with synthetic fibers which can potentially reduce the cost of the hybrid composites. This work presents an experimental study of mechanical characterization of Glass/Sisal fiber re inforced epoxy hybrid composite materials. Five cross plyhybrid composite laminates containing four laminas with different hybrid ratios were fabricated by the vacuum assisted resin transfer molding (VARTM) technology and tested under tensile, bending and impact loads. The hybrid composite laminates fabricated with several combinations of glass and sisal fibers volume fractions (25 % glass + 25 % sisal, 30% glass + 20% sisal, 35% glass + 15% sisal, and 20% glass + 30% sisal, 15% glass + 35% sisal) were considered to investigate the properties of the hybrid composite laminate. The hybrid composite laminates showed variable experimental results for each different weight ratios of the two reinforcements. The experimental results shows that the tensile strength of the cross-ply hybrid composite laminates increase up to 37% when compared to composites laminates made from only pure sisal fiber and the tensile strength increases up to 17% when compared to pure glass epoxy composite material. The glass/sisal epoxy hybrid composites have a density between 1 g/cm 3 and 1.3 g/cm 3 . Generally, from those experimental tests, it is found that there was significant variability in density, tensile strength, flexural strength, and impact resistance properties of the hybrid composite materials due to the variation in volume fractions of sisal and glass fibers.
