Investigation and assessment of mechanical properties for FRP (Fiber Reinforced Polymer) composites have been instrumental in qualifying it for the final use. Pronounced among mechanical properties is flexural strength which diversifies with varying test span length, Specimen depth and temperature for different materials. Current work focuses on unearthing the optimum span length of epoxy Glass fiber reinforced composites for which flexural strength is to be scrutinized. Investigations for flexural test in accordance to ASTM Standard D790 are executed by altering the span lengths to acknowledge the functioning of the flexural modulus and strength thereby acquiring an optimum span length, which, can be employed by the composite designers and manufacturers to engineer meliorated testing procedures. From the experimental results it is found that the composite failed by shear mode at lower span lengths.
