Abstract

In a Nano-composite structure, it is anticipated that high damping can be achieved by taking advantage of the interfacial friction between the nanotubes and the polymer. The purpose of this paper is to investigate the structural damping characteristics of polymeric composites containing Carbon nanotubes (CNTs) with various amounts with polysulfide rubber (PSR) . The damping characteristics of the specimens with 0 wt% and 0.6 wt% Carbon nanotube contents were computed experimentally. Through comparing with neat resin specimens (epoxy, epoxy +PSR), the study showed that one can enhance damping by adding CNTs fillers into polymeric resins. Similarly experiment showed that the maximum value of damping ratio was obtained at 0.4 wt% CNTs.

لوحظ انه في المواد المختلطة النانوية يمكن الوصول الى تخميد عالي بالاستفادة من الاحتكاك بين الانابيب النانوية والمادة البوليمرية .الهدف من هذا البحث هو دراسة خواص التخميد في الهياكل للمادة المختلطة المدعمة بالأنابيب النانوية لمختلف نسب المطاط . خاصية التخميد للعينات لنسب الانابيب بين 0-0.6% تم دراستها واختبارها عمليا. ومن خلال المقارنة مع المادة الخام للقاعدة والقاعدة مع المادة المضافة لوحظ ان التخميد تحسن بإضافة الانابيب النانوية للمادة الخليطة. و اظهرت النتائج العملية ان اكبر قيمة لنسبة التخميد (عامل التخميد) هي عند اضافة 0.4% من الانابيب النانوية للكربون.

Abstract

Carbon nanotubes are an ideal material for infrared applications due to their excellent electronic and photo electronic properties, suitable band gap, mechanical and chemical stabilities. Functionalised multi-wall carbon nanotubes (f-MWCNTs) were incorporated into polythiophen (PTh) matrix by electro polymerization method. f-MWCNTs/ PTh nanocomposit films were prepared with 5wt% and 10wt% loading ratios of f-MWCNTs in the polymer matrix. The films are deposited on porous silicon nanosurfaces to fabricate photoconductive detectors work in the near IR region. The detectors were illuminated by semiconductor laser diode with peak wavelength of 808 nm radiation power of 300 mW. FTIR spectra assignments verify that the thiophene groups were successfully introduced into the carbon nanotubes. SEM images reflect that the electro polymerization process gives well incorporated for the MWCNTs by PTh polymer. Characteristics of photodetector were improved after cooling the detector. Figure of merit showed a good IR radiation sensitivity and photo response, while the specific detectivity was in order of 109 cm.Hz1/2/W and at for both MWCNTs loading ratios at forward bias voltage 5 Volts. The rise time and fall time of the output signal are about 192 μs and 121μs respectively which consider good values for these types of detectors

On the otherhand, seventy five disc shaped specimens (50mm diameter and 0.5mm thickness) were prepared for color stabilitytest. They were divided into two groups according to the nanofillers used ; silanated and non-silanated ZrO2nanofillers, for each group Three subgroups were prepared (one control and two(3% and 5%) for the silanated andnon-silanated ZrO2 nano-fillers. Impact strength test was carried out with charpy type impact testing instrument. Whiletensile strength test were done by using Jain Qiao equipment system. . On the other hand, color stability wasobjectively assessed by using a spectrophotometer device after 48 hours immersion in three different solutions(distilled water, cola and tea) and the amount of light absorption was calculated. Impact and tensile strengthmeans (in MPa) and color stability means (in nm) were analyzed statistically by analysis of variance and thecomparative T-test and least significance test (LSD).Result: Significant increase in impact strength occur in acrylic reinforced with 5% wt silanated (ZrO2) nanofillers , butnon significant increase was observed at 5% wt non-silanated (ZrO2) nanofillers when compared with control group.On the other hand, there were non-significant improvements in the tensile strength for all groups of (ZrO2)reinforcements. While for the color stability test data showed significant increase in the light absorptions forspecimens reinforced with (ZrO2) nanofillers when compared with control group. on the other hand, there were nosignificant difference observed between specimens reinforced with non-silanated and silanated (ZrO2) nanofillers.Conclusion: the findings of this study showed that Silanaized ZrO2 nano-fillers is effective in improving impact strengthwhile it was not effective in improving the tensile strength, the maximum increase in impact strength was observed indenture base nano composite containing 5% wt of silanated ZrO2 nano-fillers. On the other hand, significant colordifferences were detected between control group and specimens incorporated with zirconium oxide nano-fillers atdifferent immersion solutions

Abstract

Al2O3 is a major reinforcement in aluminum-based composites, which have been developing rapidly in recent years. The aim of this paper is to investigate the effect of alumina phases and amounts on the physical properties of fabricated Al-Al2O3 composite. Alpha micro and gamma nano of alumina with particle size of 30µm and 20 nm respectively reinforced aluminum matrix of 45 µm. The percentage of reinforcement material were in the range of (5, 10 and 15wt.%) fabricated by powder metallurgy technique. Specimens dimensions were a disc specimens with 11mm diameter and 5 mm thickness. The green density was achieved under compaction pressure of 500MPa, and then sintered under pressure less sintering at 500ºC in a vacuumed tube furnace for two hours Physical properties of the composite samples have been studied such as relative density, sintered density, porosity, microstructure characteristics, particles distribution, agglomeration, grain sizes and granularity accumulation distribution. It has been noticed that at the micro alumina phase, its relative densities are decreased when there is an increase in amount of micro alumina addition, on the contrary in case of nano composites, where the relative density are increasing along with the increase in nano alumina addition. At micro and nano composites, the produced relative densities are less than the pure aluminum relative density. Agglomeration are increasing with the increase in amount of reinforcement, while its more obvious with nano composite. Grain size reduced with the increase in amount of alumina in micro and nano composites, while, the obtained average grain size diameter is less in nano composite than in micro composites. It is obvious from the results that the variation in physical properties and microstructure of Al-Al2O3 composite are depends on both of alumina phases (size) and percentages. At 15wt.% of nano alumina higher relative density and lower porosity will be obtained.

يعد الالومينا Al2O3 من المقويات الشائعة في مركبات الالمنيوم والتي قد تطورت بسرعة في السنوات الاخيرة. ان الهدف من البحث المقدم هو دراسة تأثير طور الالومينا وكميته على الخواص الفيزياوية لمركب Al-Al2O3 المصنع. لقد تم استخدام مادة الالومينا بصيغة الالفا وبالحجم المايكروي ومن ثم بصيغة الكاما وبالحجم النانوي وقد كانت حجومهم 30µm ثم 20 nm على التوالي لغرض تقوية مادة الالمنيوم والتي كانت بحجم 45 µm . لقد تم استخدام المواد المقوية المضافة بنسبة وزنية قدرها (5% و 10% و 15%) . تم تصنيع العينات بتقنية ميتالورجيا المساحيق على شكل قرصي وبقطر قدره 11ملم وسمك قدره 5ملم . لقد تم الحصول على العينة الخضراء بتسليط ضغط قدره ( 500 ميكاباسكال ) ومن ثم تمت عملية تلبيد العينات ومن دون تسليط ضغط وباستخدام فرن انبوبي مفرغ لمدة ساعتين وتحت تأثير درجة حرارة مسلطة قدرها (500 درجة سيليزية ). تمت دراسة الخواص الفيزياوية لعينات المركبات كالكثافة النسبية والكثافة العملية والمسامية و الخواص الهيكلية وتوزيع الدقائق والتكتل والحجم الحبيبي والتوزيع التراكمي الحبيبي. لوحظ انه في في حالة المركبات التي تحتوي على المايكرو الومينا فأن الكثافة النسبية تقل مع زيادة نسبة الالومينا المضافة على العكس عنه في حالة المركبات التي تحتوي على النانو الومينا فأن الكثافة النسبية تزداد مع زيادة أضافة مادة النانو الومينا. علما بان في كلتا المركبات المايكروية والنانوية تكون الكثافة النسبية للمركب أقل من الكثافة النسبية للالمنيوم النقي . لقد لوحظ بان التكتل في المركبات يزداد بزيادة المواد المقوية المضافة وهو اكثر وضوحا في مركبات النانو. يقل الحجم الحبيبي مع زيادة كمية الالومينا المضافة في المركبات المايكروية والنانوية الناتجة على حد سواء، في حين ان معدل قطر الحجم الحبيبي لمركبات النانو هو اصغر منه في مركبات المايكرو. يتضح من خلال النتائج التي تم الحصول عليها بان التغير في الخواص الفيزيائية والهيكلية لمركبات الـ (Al-Al2O3 ) الناتجة يعتمد على كل من طور الالومينا (الحجم) وكذلك النسب الوزنية المضافة . عند النسبة الوزنية 15% من النانو الومينا تم الحصول على اعلى كثافة نسبية واقل مسامية للمركب الناتج.
