The majority of known polymer materials are electrically insulating. But there are some of polymers are intrinsically conducting in nature, However, it is lacking in process ability, and the scope for manipulation of electrical and mechanical properties is limited. The method which used to solve this problem is an addition of a conductive metal filament into a polymer filament yarn. Which can be directly integrated into a textile, or can be knitted. So we made a device able to produce this kind of conductive yarns which depends on melt spinning technique but with the elimination of necessary pressure for extrusion. And we were able to produce samples of copper filament coated with polymeric material (low density polyethylene).

هدف البحث: إن استخدام الرماد في صناعة السيراميك هو عمل بيئي يسهم في الحفاظ على الموارد الطبيعية، و يساعد في التخلص من النفايات، و يعد خطوة اقتصادية هامة لأنه يخفف من تكاليف صناعة السيراميك إذ إنَّه لا يحتاج إلى عمليات تصنيع مثل الطحن أو السحق. من هن ا كان هدف البحث دراسة إمكانية استعمال الرماد، الناتج عن مختلف أنواع الصناعات، بوصفه مادةً أوليةً في صناعة السيراميك المستخدم لتغطية الجدران و الأرضيات. طرائق البحث : اعتمد البحث على الطرائق التجريبية المخبرية لاستخدام الغضار و الرماد (بنسب مدروسة مخبرياً)، كمواد أولية للحصول على الخلطة اللازمة في عملية تصنيع سيراميك الأرضيات و الجدران. و من ثم تم اختبار كل من المقاومة على الكسر و نسبة امتصاص الماء على العينات المشكلة من هذا الخليط و قارنا نتائج هذه الاختبارات بالمتطلبات العالمية لهذه الصناعة. النتائج : في هذا البحث تم التوصل إلى تحديد النسب الملائمة لمكونات الخلطة اللازمة لصناعة السيراميك مع تحديد المعايير و البيانات التي تساعد في نقل هذه التكنولوجيا إلى الواقع الصناعي التجاري.
The research includes an experimental study for the manufacture of composite material based on polymer ( unsaturated polyster) reinforced with wool fiber at different weight fractions ( 0.5 % - 1% - 2%- 3% - 4%- 5 % ) and then it has been studied some mechanical properties
We, in Al AHLIA Company for RUBBER and Plastic Products - Damascus by Coordination with Damascus University, prepared a typical blend for local production of the electric generators elastomeric couplings. That was achieved after a detailed analysi s of the properties of the imported couplings. To confirm our aims, we used the available materiales, equipment and machines in the company. The coupling moulded by a press machine type CAPANAING BENEPETO.
In this study we used electro spinning technology to obtain nonwoven webs of Nano fibers of poly vinyl alcohol and Nano particles of silver . we dissolve the polymer poly vinyl alcohol in it's solvent (water) to form a polymeric solution that we c harged it by positive charge and ejected it to leaving it on a collector that we charged it by negative charge and used a high voltage. and we mixed the polymer poly vinyl alcohol with silver nitrate with different concentrations and electro spinning the mixture to obtain Nano fibers and Nano particles of silver then we applied heat treatment for the whole samples at 155°c for 5 minutes for tow aims the first one is to make crosslinking between series of PVA and the second is for the stability of silver nanoparticles , finally we analyze samples on Scanning Electron Microscopy SEM .
