Fiber reinforced polymer (FRP) composites have an important role in many industries; because weight to strength ratio is extremely high when compared to monolithic metals. One of the main limitations of FRP composites are the low mechanical properties duo to the presence of polymer associated with it. To solve this problem, materials engineers are investigating the use of different nanoparticles mixed in different polymers to improve mechanical properties of the polymer. Here epoxy - silica nano composites are tested as matrix face for Glass Fiber Reinforced Plastic using Vacuum bagging technique and autoclave technique and it's improvement in mechanical properties such as tensile strength, tensile modulus, flexural strength are investigated . And also in this study, behavior of nano filled glass fiber reinforced polymer under uniaxial tensile loading and transverse mid span loading are determined at different strain rates such as 5, 50,500 mm/min. The tests were performed using Universal Testing Machine. Experimental result shows slight decrement in tensile properties and slight increment in flexural properties of the material by increasing the strain rates.
