Fabrication and Mechanical Behavior of E-Glass fiber based composites

Polymer composites have good characteristics like modulus/weight ratio, strength/weight ratio, excellent fatigue and non-corroding properties which encourage to the extensive applications. This study was about the orientation of fiber effects on the mechanical properties of E-glass reinforced polymer composites which is essential. For three different orientations (00/900, 00/450 & 00/1350) of fiber, epoxy laminated composites are fabricated by hand-layup technique and these specimens were subjected to tensile, flexural and hardness testing as per the ASTM standards. This paper evaluates the comparison of different orientation of E-glass fiber in order to improve the strength and hardness. The experimental results reveal the best tensile strength & hardness values are obtained for 00/900 oriented fibers, flexural strength is for 00/450 orientations specimen. Regression analysis is utilised to check the validity of the experimental data. The results demonstrated that the created quadratic models are suitable for the prediction of experimental values for mechanical properties.
