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