يتناول هذا البحث تحضير مادة مركبة من بوليمير الايبوكسي و هباب الفحم و دراسة تأثيره في بعض خصائص سلوك البلمرة و لاسيما تفاعل التصالب و مردوده و بعض خصائص المادة المركبة مثل درجة حرارة الانتقال الزجاجي للبوليمير(Tg) و بعض الخصائص الميكانيكية كمعامل يونغ (E) و مقاومة الانعطاف (σ). وصف تفاعل التصالب و درجة حرارة الانتقال الزجاجي باستخدام جهاز التحليل المسعري التفاضلي الماسح (DSC) و أُجريت الاختبارات الميكانيكية بواسطة جهاز الاختبارات الميكانيكية العامة.
In this research work, an epoxy polymer- Carbon Black composite has been prepared and characterized regarding the effects of adding carbon black to epoxy polymer on some structural properties such as polymerization behavior, cross-linking reaction time and yield and some properties e. g. glass transition temperature (Tg), Young modulus (E) and flexural strength (σ). The cross-linking reaction and glass transition temperature were studied by Differential Scanning Calorimetry (DSC), and the mechanical tests were done by Universal Testing Machine.
