In this study, we have investigated the water absorption behavior of unsaturated polyester /wood flour wastes composites materials. To achieve that, specimens were prepared by using compressing method with different ratio of polymer matrix with organic wastes produced from carpentry workshop (wood flour).Density of produced panels has been measured and the obtained results showed that there is an ability to produce hardindustrial wood panels. Practical experiments had been achieved to determine the percentages of water absorption. Absorption test was achieved on the cut specimens by immersing them in natural water (un-distilled) and measuring the gained weight of specimens and the resulted swelling to determine the final changes in the product. Through this study, we find that the absorbability has increased with the increment of organic filler ratio and the practices sizes increment. In addition, we also find that the absorption behavior follow Fickian law of diffusion in most specimens. We calculated the diffusion coefficient D and other parameters of diffusion process and we also plotted the associated plotsof the absorbability results. The obtained results showed that there is an ability to produce planes of industrial wood without any pretreatment of wood flour.

Research summary
يهدف هذا البحث إلى دراسة سلوك امتصاص الماء في المواد المركبة المؤلفة من البولي استر غير المشبع وبودرة الخشب. لتحقيق هذا الهدف، تم تحضير عينات باستخدام طريقة الكبس بنسب مختلفة لمادة الأساس الرابطة البوليميرية مع النفايات العضوية الناتجة عن ورش النجارة. تم قياس كثافة الألواح المصنعة وأظهرت النتائج إمكانية الحصول على ألواح خشب صناعي من النوع القاسي. تم إجراء تجارب عملية لتحديد النسبة المئوية لامتصاص الماء، حيث تم غمر العينات في الماء العذب غير المقطر وحساب الوزن المكتسب والانتباج الحاصل لمعرفة التغيرات النهائية في المنتج. أظهرت الدراسة زيادة الامتصاصية مع زيادة نسبة المالئ العضوي وحجم الحبيبات، وأن سلوك الامتصاص يخضع لقانون فيك للانتثار في أغلب العينات. تم حساب معامل الانتشار D والبارامترات المعبرة عن عملية الانتشار ورسم المخططات البيانية المرافقة لنتائج الامتصاصية. النتائج أظهرت إمكانية تصنيع ألواح من الخشب الصناعي دون الحاجة إلى المعالجة المسبقة لبودرة الخشب.
Critical review
دراسة نقدية: يعتبر هذا البحث إضافة قيمة إلى مجال دراسة المواد المركبة، خاصة في سياق استخدام نفايات الخشب. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية الأخرى مثل درجة الحرارة والرطوبة على سلوك الامتصاص. ثانياً، قد يكون من المفيد إجراء مقارنة مع مواد أخرى مشابهة لمعرفة مدى تفوق هذا النوع من المواد المركبة. ثالثاً، يمكن تحسين الدراسة بإجراء تجارب إضافية على المدى الطويل لتحديد مدى استدامة هذه المواد في ظروف مختلفة. وأخيراً، يجب أن يتم توضيح المزيد من التفاصيل حول عملية التحضير والتصنيع لضمان إمكانية تكرار النتائج بسهولة من قبل باحثين آخرين.

This experiment investigates the effect of aluminum powder as metallic filler of unsaturated thermosetting polyester resin on the wear rate and its mechanisms according to time. The obtained results show that the rate of wear increases with increa se of time as a result of increase the temperature generated of friction in all specimens. But when we add the particles either Aluminum to polyester matrix, the rate of wear reduce as a result of increase the thermal conductivity of polyester matrix, that leads reduction of the temperature of contact surface, that leads less wear. We study the mechanisms of wear by microscope of the worn surface. It found that the predominant mechanisms of wear vary from adhesive wear at the lowest value of test time to abrasive wear (3- body) at the highest value of test time.
This paper is targeting towards studying on the possibility to modify some properties of unsaturated Polyester compounds by adding rubber materials in order to improve its flexibility property. For this target, Waste of cars' tires was used in two forms powder and pieces, and the liquid rubber Styrene-butadiene was used as another type of rubber. After that the modification was detected by measuring the possibility of the resulted compound materials to absorb vibration power, and reduce the noise that is produced by eccentric crankshaft circulation at different rotating speeds, (300, 500, 700) rpm. Test results demonstrate that there will be Modification in the construction of the compounds at low rotating speeds (300 rpm). On the other hand, it demonstrates different results at high rotating speeds.
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
