Abstract
Natural fiber composite materials are grabbing the attention of industries due its eco-friendly and sustainability. These are effectively replacing many of metals and ceramic comprised components in termsof accessibility, cost, strength and weight. The study of a material to resist a load which is having cracks internally is the important parameter, this which internally describes the fracture toughness of a material. Understanding of flexural strength (bending strength) helps to avoid the internal de-lamination. In this research a composite specimen is prepared using a naturally available hemp fiber along with commercially available E-glass. Traditional hand layup fabrication method is used to prepare the composite specimens. Fracture test specimen is prepared according to ASTM E399 and the flexural (bending) specimen is developed according to ASTM D790. The fracture toughness of the hemp/E-glass composite has with stand a critical load of 1192N with a yield stress of 50MPa. The fracture toughness strength up to 11.77MPa can be with stand by the composite specimen. Fracture toughness increases with respect to the alignment. Orientation of fibers increases the strength. Bending strength resist by the composite laminate is about 4.8MPa and this will be decreased due the improper bonding between the layers. SEM test helps to identify the reasons for failure
