In this paper an experimental investigation of unsaturated polyester(UPR) with different weight fractions(2,4,5,7 )wt% of (Al2O3,MgO,TiO2) as powders ,has been done. the identification of their flammability and fire resistance ranges are found out . the time needed to puncture the samples, the mass loss, the diameter variation ,and the flame effect on the samples surface are measured. the samples were tested by Oxyacetylene flame using a device which is designed in the Faculty of Mechanical and Electrical Engineering labs. The results showed that (MgO) is the best one for its flammability and fire resistance. The longest time before puncture , and the lowest mass loss were achieved by( UPR+ 7% MgO) with(16% mass loss in 112 sec ), while pure UPR has ( 27% mass loss in 45 sec).

Research summary
تناول البحث دراسة تجريبية لتأثير إضافة نسب ضئيلة من أكاسيد المغنزيوم والألمنيوم والتيتانيوم على مقاومة اللهب للبولي استر غير المشبع. تم قياس الزمن المستغرق لتقب العينات، الفقد في الوزن، والتغير في القطر بعد الحرق. أظهرت النتائج أن أكسيد المغنزيوم هو الأفضل من حيث مقاومة اللهب، حيث حققت العينات المضاف إليها 7% من أكسيد المغنزيوم أطول زمن للتقب وأقل نسبة فقد في الوزن مقارنة بالعينات الأخرى. كما أظهرت النتائج أن أكسيد الألمنيوم والتيتانيوم قدما نتائج إيجابية ولكن بدرجة أقل من أكسيد المغنزيوم. تم استخدام جهاز خاص لاختبار الحرق تم تصميمه في مخابر كلية الهندسة الميكانيكية والكهربائية بجامعة تشرين.
Critical review
دراسة نقدية: يعتبر البحث ذو أهمية كبيرة في مجال تحسين مقاومة اللهب للمواد البوليمرية، إلا أنه يمكن توجيه بعض الملاحظات النقدية. أولاً، لم يتم التطرق بشكل كافٍ إلى تأثير هذه الأكاسيد على الخواص الميكانيكية للبولي استر غير المشبع بعد إضافة الأكاسيد. ثانياً، كان من الممكن توسيع نطاق الدراسة ليشمل أنواع أخرى من الأكاسيد المعدنية أو نسب إضافة مختلفة للحصول على صورة أشمل. وأخيراً، لم يتم تقديم تحليل مفصل للبنية المجهرية للعينات بعد الحرق، وهو ما يمكن أن يضيف قيمة علمية أكبر للبحث.

This search aims to study the effect of additive materials ( Ethyl Methyl Keton Peroxide MEKP , Cobalt Naphthenate ) at the important values of (stress-strain) curves ( stress and elongation at break ) for the preparing specimens from reinforced an d nonreinforced with fiber glass unsaturated polyester resin. The result showed that the investigated parameters are clearly affected with using additive materials and the optimum concentration for non-reinforced specimens which was curing in room temperature was (1% MEKP + 1% Cobalt Naphthenate) and (0.8% MEKP + 1% Cobalt Naphthenate), and for reinforced specimens with fiber glass was:( 1% MEKP + 0.8% Cobalt Naphthenate) and ((0.2-0.4) % MEKP + 1% Cobalt Naphthenate). The results showed also that it is possible to get the better values of tensile stress at break when the specimens was curing in oven at 100 Cº and treated at this temperature for 15 min.
This research aims to study the effect of adding inorganic waste (Marble powder - glass powder) on the volumetric and longitudinal shrinkage curves at unsaturated polyester resin, tests showed that samples exposed to volumetric and longitudinal shr ink and occurrence of consecutive gradients in volumetric shrinkage values. Whatever the ratio of the added materials (marble powder - the glass powder) will effect the behaviour of the unsaturated polyester hardening, that means it will effect the volumetric shrinkage. It is necessary to study the volumetric and longitudinal shrinkage values because they affect the product size to be dealt with, this value should be taken into account in the design so that should be added this amount of volumetric shrinkage to the dimensions to designed templates in order to avoid potential variations occurring in the final product. Preliminary results showed that the value of volumetric shrinkage got up (5%) and the curves tend to stability, almost three weeks after the initial hardening incident.
This research aims to study the effect of heat treatment on curing of reinforced Unsaturated Polyester Resin (UPR) with fiberglass, and to study the effect of storage time and the time of exposure to natural aging on curves absorption. The results showed that it is very difficult to reach a fully curing to UPR matrix, and Storage samples for three years reveal resistance to degradation in fresh and seawater comparing with storage samples for three months, or aging by exposed to environmental for three years. The results showed also that the absorption occurs by thin film, and not prevent by increasing the layers of reinforcement
As a result of the development of the use of reinforced Composites with fibers in practical applications continuously, research aims to study the effect of proportion piroxide additives to unsaturated polyester resin on the tensile properties of th e samples prepared from unsaturated polyester resin reinforced with glass fiber used in wind turbine blades manufacturing, and also studying the effect of for the application of heat treatment operations on the hardening of the unsaturated polyester and tensile properties after heat treatment process the application in order to improve the properties of these blades. Test samples were prepared containing ratios (1% - 1.5% - 2%) of methyl Etel ketone piroxide MEKP and test results showed that the best ratio at 1.5%. While the heat treatment results showed that the best values for tensile strength at break of the samples are treated to a time of / 48 hours /.
