In this research the Experimental study of glass fiber composite materials reinforced fiber typesrnare presented. Composite materials have boundless engineering applications where the strengthrnto weight ratio, low costs, and ease of fabrication are required. The main goals of this researchrnwork were to characterize the mechanical properties and study the water absorption of behaviorsrnof glass fiber reinforced composites materials using Experimental test. Different literature orrnresearch uses different fiber/matrix ratio for composite materials preparation, fabricate and testrnthe mechanical properties, using literature as a reference four different types of fiber/matrix ratiornof the specimen were prepared. WP 310 universal testing machine were used to test mechanicalrnproperties. The tensile, compression and flexural properties of the glass fiber reinforced Epoxyrncomposite materials were carried out According to ASTM standard. The 50/50 fiber matrix ratiornwas found higher tensile strength,45/55 fiber/matrix ratio (45%) fiberglass fiber-reinforcedrncomposite materials was found higher compressive strength and 25/75 fiber matrix ratio of glassrnfiber reinforced composite materials were found higher flexural strength and also glass fiberrnreinforced composite materials specimens were poured in the ordinary water for the various timernintervals at room temperature to study the water absorption effect at different periods of times.rnThe water absorption of the specimen shows gradual increases. The effect of water gain in thernpercentages for glass fiber reinforced composite was observed. Furthermore, the results show,rnusing the glass fiber as reinforcement could successfully develop composite materials in terms ofrngood strength and better water absorption properties for the uses of lightweight purpose ofrndifferent application.
