Experimental Investigation of Tensile Strength of Fiber Reinforced Polyester by Using Chicken Feather Fiber

Due to the rebar corrosion problems, quite the value of construction is being spent towards repair and renovation of the concrete structures. If rebar corrosion problem continues, lifeline structures are subjected to sudden collapse. So as to avoid the catastrophic failures, effective additional protective measures must be undertaken within the construction stage itself. The target of this investigation is to switch the surface of the low-carbon steel rebar by electroplating in three different coating thicknesses. The efficiency of corrosion resistance properties are evaluated by various electrochemical corrosion tests. This study starts from Brenner and Riddel who developed their work by electroless deposition of nickel. the aim of this study was to calculate the corrosion rate by gravimetric weight loss method supported the electrochemical corrosion test. Also to reinforce the performance of corrosion resistance with three different coating thicknesses like 10µ, 20µ, and 30µ supported the time consumption in low-carbon steel rebar with and without 3.5% Nacl. Potential time studies confirmed the steadiness of coating even within the presence of aggressive chloride medium during one month exposure. 12V accelerated impressed voltage test results indicate that the time taken for initial crack was doubled for 20µ coated steel.

“…As Van de Velde and Beatens [17] reported, after 300℃, the degradation of lignin, cellulose, and hemicelluloses present in the fiber was more rapid and major weight loss was observed. Loganathan et al and Loganathan et al [18,19] said that percentage variations of Chicken feather fibre have an important effect on the tensile strength as well as the yield strength from the experimental tensile and yield strength analysis research on composites of pure jute fibre with Chicken feather fibre. Sreekumar et al [20] investigated the thermal behavior of treated and untreated sisal fiber reinforced polyester composites.…”

et al. 2021

In this study, an attempt was made to develop and characterize Snake Grass Fiber (SGF)/Silicon Carbide (SiC)/epoxy and Snake Grass Fiber/Sisal Fiber (SF)/Silicon Carbide/epoxy hybrid composites using a compression moulding technique. Mechanical characteristics of the produced hybrid composites such as tensile, flexural, and hardness tests were analyzed. Also experiments have been carried out to predict the thermal stability of the fabricated composite samples. The interface between fiber and matrix was examined by using Scanning Electron Microscopy (SEM). Among SGF/SiC/epoxy and SGF/SF/SiC/epoxy composites, it has been observed that hybrid composite SGF/SF/SiC/epoxy exhibits the higher hardness of 82 Shore-D, tensile strength of 51 MPa and flexural strength of 73 MPa. In contrast to the mechanical properties, the percentage of water absorption was lower in the SGF/SiC/epoxy hybrid composite. It is proven from the results that the SGF/SF/SiC/epoxy hybrid composites will enhance the strength of the composites. This composite material is also a potential candidate for the hardware of energy devices including electrochemical energy along with Fuel Cell systems.

“…The early results also suggest that the Magnesium silicate hydrate gel also gave a X-ray powder patterns indicative of 2D crystals without any basal space, and had developed a specific area of 300 Sq m/g, and gave an exothermal effect at greater than 800°C . Innovative materials such as fly ash, silicon and fibers are used for making composites [9][10][11][12].…”

This research work is to investigate the strength, shrinkage and hydrogen ion concentration of concrete admixed with magnesium binder. The magnesium binder is manufactured through calcination process at a temperature of 1200 degree Celsius. The raw materials for the magnesium binder are magnesite (magnesium carbonate) and steatite (magnesium silicate). The calcined powder is also mixed with phosphate salt for better performance. The magnesium binder is replaced to cement in the proportion of 0% to 30% and the samples were tested in laboratory conditions from 1 day to 360 days for its strength. The shrinkage is tested until 130 days and the pH value is tested on 28 days hardened concrete samples. The results show that the magnesium binder replacement has refined effect on pore structures which attributed to the better performance in strength and shrinkage.
