دراسة خاصية التوصيل الحراري في ظروف مختلفة لمواد متراكبة دقائقية

Abstract

Study the evaluation of coefficient of thermal conductivity for different composite materials based on polymeric (unsaturated polyester) with glass powder (flint), Calcium Carbonate (CaCo3) and magnesium oxide (MgO) with volume fraction (30%) using hand lay- up technique in preparation of moldes. Study included also the variation of thermal conductivity (k) in different conditions (heat to 40C∘ and 50C∘ and also immersion in water for 60 days
