Braided Hybrid Composites for Bridge Repair
Mechanical properties of hybrid braided composite rebars are evaluated and compared to theoretical predictions which account for specific processing parameters including yarn size, braiding machine setup, and fiber type. Using a combination of high modulus carbon (Thornel P-55S) and aramid (Kevlar 49) fibers bars have been produced of up to 10 mm diameter with a Young's modulus of 200 GPa, a bi...
متن کاملA Tensile Split Hopkinson Bar for Testing Particulate Polymer Composites Under Elevated Rates of Loading
A tensile split Hopkinson bar apparatus is developed for testing high strain rate behavior of glass-filled epoxy. The apparatus uses a specimen gripping configuration which does not require fastening and/or gluing and can be readily used for castable materials. Details of the experimental setup, design of grips and specimen, specimen preparation method, benchmark experiments, and tensile respon...
متن کاملa new approach to credibility premium for zero-inflated poisson models for panel data
هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولPREDICTING THE STIFFNESS OF BIAXIAL BRAIDED FIBER COMPOSITES BY INCORPORATION OF CARBON NANO FIBER
In this study, carbon nano fibers (CNFs) were mixed into epoxy resin through a magnetic stirrer and again mixed using ultra sonicator. Using hand layup technique, biaxial braided fiber composites were prepared with unfilled, 0.2, 0.5 and 1 wt% CNF. Tensile test and shear test was performed to identify the tensile strength and shear strength of the composites. Fractured surface of the tensile sp...
