دراسة تأثيرات عامل التعتيق على كفاءة أداء الكلال لمادة متراكبة بوليمرية المادة الأساس

الملخص EN

In this research a study of the effect of aging factor on behavior of binding fatigue of resin (Dia Ethylene Bisphenol Epoxy-A) which is reinforced by adding volume ratio (33.3%) of (SiO2) powder and (44.4%) of (Al) powder, those samples were kept under open conservation condition for different time periods (2,4,6) years.

Fatigue test was conducted for unreinforcement and reinforcement samples.

The results have shown that there are an improvement in fatigue life in reinforcement matrix and this improvement depend on the nature of reinforcement material.

and the results have shown that the efficiency of fatigue life for unreinforcement and reinforcement matrix is decreased with increasing age of aging and the matrix which is reinforced by (SiO2) powder be less sensitive from matrix which is reinforced by (Al) powder and both are less sensitive from unreinforcement matrix .

Finally, the results show that the damage to the material is the type of quantitative damage and that is likely to be the matrix is responsible of such damage.
