Abstract: This paper presents the mechanical behavior of sisal/glass fiber reinforced polyester hybrid composites. Sisal fiber has been hybridized with glass fiber reinforced polyester using hand lay-up process to improve the mechanical properties. Test specimens were prepared using glass fiber (GF) /sisal fiber of 30/70, 50/50 and 70/30 weight fraction ratios as per ASTM standards and mechanical properties like tensile, impact and flexural strength of sisal /glass fiber reinforced polyester are evaluated and compared. The results shows that tensile strength of 30 %GF-70 %sisal composition and flexural strength of 70 %GF-30 %sisal composition and impact Strength of 50 %GF-50 %sisal composition is found to be better than the remaining two compositions.
