【 摘 要 】

In this work some mechanical properties of epoxy resin (DGEBA)/silica oxide (SiO2) reinforced with different weight percentage (5, 10 and 15) fiberglass investigated. A homogeneous solid colorless samples were prepared at room temperature using disposable stirrer. The study used the comparison of fiberglass different percentage concentration in order to improve strength and tenacity. Moreover, the effect of silica oxide presence in order to improve the interface surface. The results showed that (DGEBA) epoxy resin with 15% fiber glass has high tensile strength, impact and hardness. Furthermore, the addition of fiber glass improves the fracture toughness of the epoxy resin (DGEBA) and the amount of toughness. Besides, the presence of silica oxide within the sample structure led to greater coherence between the fiberglass and other parts of the composite, this is illustrated by SEM images for selected samples.
