Abstract AR
في هذه الدراسة تم تحسين الخواص الميكانيكية للمادة الرابطة بإضافة المطاط.
تم استخدام الزجاج بنسب مختلفة كألياف تقوية، أوكسيد المولبدنيوم الثلاث و كربونات الكالسيوم استخدمت كمادة مالئة، أوكسيد الزركونيوم استخدم كمادة حاكه و كبريتات النخاس كمادة مزيتة.
الدراسة الحالية حسنت مواصفات ثلاث راتنجات هي (1) المطاط السليكوني (SIR) للنوفلاك (2) مطاط (SBR) للنوفولاك (3) مطاط (NBR) للنوفولاك.
استخدم المطاط السليكوني و (NBR) لأنه يتحمل درجات الحرارة العالة و قد تم استخدامه مع عدة نسب للألياف لمقارنة تأثيرها على الخواص الميكانيكية.

Abstract EN
In the present study the rubber was added to novolac resin as a binder to improve the mechanical properties.
Glass fibers and steel fibers were used at different ratios as a reinforcing fibers, molybdenum trioxide and calesuim carbonate as filler, zirconium oxide as abrasive material and copper sulfides as a lubricant.
The current work investigates the characteristics of three resins: (i) SIR with novolac resin (ii) NBR with novolac resin (iii) SBR with novolac resin.
The addition of SIR or NBR was used because it undertakes the high temperature and has good chemical resistance.
The SIR was used with deferent weight ratio of fibers to compare its effect on the mechanical properties.
The samples were prepared by using cold pressing at (250MPa) .The samples were cured at (80oC).
Wear test was carried out by using pin on disc test system.
Results from the present study showed that the friction coefficient and wear rate varied with the change of the resin and fibers ratio.
The result showed that NBR and SIR addition proved best in terms of impact strength, hardness, wear rate and friction coefficient result but SBR showed poor result.
The NBR addition had better wear results than SIR.
The high ratio of fibers decreases the wear rate and increases the impact strength and friction.
