چکیده
In the present research, the mechanical properties of natural fiber reinforced polymers (NFRP) – known as green composites – have been investigated. After a large literature review done on the physical properties of a large setof natural fibers, an analytical model is used to determine the all 3D elastic properties; Young’s and Shear moduli, Poisson’s ratio and the ultimate strengths for an 8H-satin fabric. The main objective is to investigate the potential replacement of the glass fiber reinforced polymer (GFRP) by the NFRP in order to reduce the high expanses. Ananalytical modeling is adopted to evaluate the 3D elastic properties and ultimate strengths based on a multi-scale homogenization method. Tsai-Wu and Christensen Failure criteria and a damaged stiffness model are used to predictthe failure of composites. A Flax fiber reinforced polymer has shown better mechanical properties with a twice specific modulus and better specific strength compared to the GFRP.کلیدواژه ها

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.
