This research included preparation of two types of fiber composites and the the basis as ato break the stereotypes and manual volumetric rate of 25% . The characterization of the fiber is divided into two types:Overlapping material composed of epoxy resin as a subsidized two layers and four layers , six layers of fiber glass basis of the type (E-Glass) is woven mat.Overlapping material composed of epoxy as supported by two layers and four layers , six layers of caors rock wool fibers basis . In this paper the hardness characteristic study of the above complexes in natural conditions and after immersion normal water for different time periods is (5,10,15) days at room temperature . The results showed the process that the value of surface hardness for both types of specimens in natural conditions increases with the number of layers of reinforcement and that the value of the complexes fiberglass higher than the value of the complex rock wool fibers , after immersion the samples with water usual noticed that the surface hardness decreases with increasing duration of water immersion and with increasing number of reinforcement layers and both types of complexes , but their value in the complexes, fiberglass largest of its value for the characterization of rock wool fibers .
