دراسة تأثير إضافة مسحوق الألمنيوم على بعض الخواص الميكانيكية و مقاومة الاحتراق للبولي استر غير المشبع

الملخص EN

The study of the effect of aluminum powder on the mechanical properties of unsaturated polyester which is manufactured in the Turkey, as function of the percentages of aluminum powder (0.5% , 0.8% , 1% , 1.5% , 2% , 2.5% ), at particular size (150) µm, were investigated through several variables, such as, young's modules, strength, elongation and the flame resistance.

The obtained results were the properties (unsaturated polyester/aluminum powder) composites were analyzed as a function of the filler amount.

All prepared composites showed improved filler dispersion in the unsaturated polyester matrix, the results lead to that the strength at break will be affected little till the percentage (1.5% ), and lowered after that with increasing the percentage also indicate an lowered in young's modules at the percentage (1% ).

The proportional limit was (2095) N for (0.8% ), and the observe that the average time of burning starts strong impact when (0.5% ) as increasing to(168 sec) and then begins to decline behavior when increasing proportions weighted and then increasing behavior when increasing proportions when (2.5% ) as increasing to (195) sec.
