چکیده

The effect of CaCO3 nanoparticles on the flexural (modulus and strength) properties of E-glass chopped strand mat (CSM)/epoxy composites was evaluated for various weight ratios (0, 0.5, 1, 3 and 5 wt.% of matrix). In this work, a silane coupling agent was used to improve the adhesion between the epoxy resin and CaCO3 nanoparticles. It was found that the addition of CaCO3 has a significant effect on the flexural properties of E-glass chopped strand mat/epoxy composites. The results showed that the highest value in the flexural strength was achieved at 3 wt. % CaCO3 addition, while the highest flexural modulus was observed at 5 wt. % CaCO3. To identify the fracture mechanisms, scanning electron microscopy (SEM) images were taken from the fracture surfaces of specimens. Micrographs of fracture surface analysis revealed that the fiber/matrix interfacial bonding can be improved significantly by the addition of CaCO3 nanoparticles in the matrix

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
