عنوان المقالة:تأثير اضافة مسحوق الالمنيوم على الخصائص الميكانيكية لراتنج الايبوكسي The Effect of Utilization Aluminum Powder at the Mechanical Properties for Epoxy Resin
In this study, polymeric composite material were prepared a by hand- layup technique from epoxy resin as a matrix and
Aluminum powder with particle size 7.1228μm as fillers with different weight percentage (0, 0.15, 0.25, 0.35, and 0.45) to resin.
Mechanical properties such as three point bending and Hardness testing were investigated. The results show the flexural modulus (E)
increase with increasing Aluminum percentage and it have maximum values of (8.1638MPa) for 45% Aluminum. Flexural strength,
Fracture stress and Deflection decreases with increasing of the Aluminum percentages compared with pure Epoxy, except the ratio
15%, the Yield Points for all Aluminum percentage increasing with increasing ratio fillers. The results of hardness test show increase
hardness with Aluminum concentration increase.
