The fiberglass is typically frivolous, durable and robust material utilized in diverse industries because of their excellent properties. The composites materials are applicable to the aerospace, construction, packaging and automotive industries. Nevertheless, there is the drawback of the polymers composites due to the unsuitability amidst the hydrophilic natural fibers and corresponding hydrophobic thermoplastic matrices, which results in undesirable properties of the underlying composites. Thus, it is fundamental to adjust the grain surface by using chemical adjustments in the bid to advance the bond amidst fiber and matrix. Different standards of ASTM apply to a wide range of fiber-reinforced polymer matrix composite materials. ASTM standard testing (or test) methods, as well as several other supporting standards, apply to fiber-reinforced polymer matrix materials. Flexural testing provides detailed procedures and analysis of various composite testing standards, including the non-ASTM test methods. The user of any given standard has a responsibility to establish the most appropriate health and safety practices, as well as to determine the regulatory limitations of particular standardsFactors influencing the underlying performance of natural fiber reinforced composites besides the hydrophilic nature of the fiber. The other properties of the natural fiber reinforced composites are fiber content. The high quantity of fiber is essential for accomplishing the high performance of the composites. Thus, the impact of fiber content regarding the properties of natural fiber reinforced composites is crucial (Vinícius et al., 2008, pp. 124-178). Moreover, an increase in the fiber loading results to an escalation within the tensile properties.
