effect of different parameters on mechanical and Erosion Wear behavior of bamboo fiber reinforced epoxy composites
International Journal of Polymer Science, 2011Co-Authors: Anu Gupta, Amar Patnaik, Ajit Kumar, Sandhyarani BiswasAbstract:The application of natural fibers as reinforcement in polymer composites has been continuously growing during the last few decades. These composites find diverse applications in hostile environment where they are exposed to external attacks such as solid particle Erosion. Also, in many respects, the mechanical properties of different polymer composites are their most important characteristics. Therefore, improvement of the Erosion resistance and mechanical behavior of polymer composites are the prime requirements in their applications. Bamboo fiber which is rich in cellulose, relatively inexpensive, and abundantly available has the potential for reinforcement in polymers. To this end, an attempt has been made in this paper not only to study the utilization potential of bamboo fiber in polymer composites but also to study the effect of various parameters on mechanical and Erosion Wear performance of bamboo fiber reinforced epoxy composites.

development characterization and Erosion Wear response of plasma sprayed fly ash aluminum coatings
Materials & Design, 2010Co-Authors: Suvendu Prasad Sahu, Amar Patnaik, K P Sreekumar, Alok Satapathy, P.v. AnanthapadmanabhanAbstract:Abstract This paper describes the processing, characterization and the Erosion Wear response of a new class of metal–ceramic composite coatings deposited on metal substrates by plasma spraying. Coatings are developed on aluminum substrates using fly ash pre-mixed with aluminum powder in different weight proportions at various plasma torch power levels ranging from 9 to 18 kW DC. The coatings are characterized in terms of thickness, interface adhesion strength and deposition efficiency. Maximum adhesion strength of about 35 MPa is recorded with coatings deposited at 12 kW power level. It is noticed that the adhesion strength of fly ash coating is improved with pre-mixing of aluminum up to 15 wt.% in the feed material. To study the Erosion Wear behavior of the coatings, a plan of experiments based on the Taguchi technique is used to acquire the Erosion test data in a controlled way. An orthogonal array and signal-to-noise ratio are employed to investigate the influence of the impingement angle, impact velocity, erodent size, stand-off-distance and the aluminum content in the feed stock on the Erosion rate. The study reveals that the impact velocity is the most significant factor influencing the Erosion Wear rate of these coatings.

study on mechanical and Erosion Wear behavior of hybrid composites using taguchi experimental design
Materials & Design, 2009Co-Authors: Siba Sankar Mahapatra, Amar PatnaikAbstract:Abstract This paper describes the development of multi-phase hybrid composites consisting of polyester reinforced with E-glass fiber and ceramic particulates. It further investigates the Erosion Wear response of these composites and presents a comparison on the influence of three different particulate fillers cement by-pass dust (CBPD), alumina (Al2O3) and silicon carbide (SiC) on the Wear characteristics of glass–polyester composites. For this purpose, the Erosion test schedule in an air jet type test rig is made following design of experiments approach using Taguchi’s orthogonal arrays. Taguchi approach enables to determine optimal parameter settings that lead to minimization of Erosion rate. The results indicate that erodent size, filler content, impingement angle and impact velocity influence the Wear rate significantly. The experimental results are in good agreement with the values from the theoretical model. An artificial neural network (ANN) approach is also applied to predict the Wear rate of the composites and compared with the theoretical results. This study reveals that addition of hard particulate fillers like CBPD, Al2O3 and SiC improves the Erosion resistance of glass–polyester composites significantly. An industrial waste like CBPD exhibits better filler characteristics compared to those of alumina and SiC. Finally, a popular evolutionary approach known as genetic algorithm (GA) is used to generalize the method of finding out optimal factor settings for minimum Wear rate.

parametric optimization Erosion Wear of polyester gf alumina hybrid composites using the taguchi method
Journal of Reinforced Plastics and Composites, 2008Co-Authors: Amar Patnaik, Alok Satapathy, Siba Sankar Mahapatra, R R DashAbstract:The improved performance of polymer-based hybrid composites in tribological applications has recently been a subject of considerable interest. A hybrid composite consists of the matrix reinforced with both fibers and particulate fillers. Alumina has the potential to be used as filler in such a multi-component system. This article investigates the effect of alumina filling on the Erosion Wear performance of glass fiber-reinforced polyester composites. For this purpose, an air jet type Erosion test configuration and the design of experiment approach utilizing Taguchi's orthogonal arrays are used. Taguchi's design eliminates the need for repeated experiments; thus saving time, materials, and cost. The systematic experimentation leads to identifying significant factors and their interactions that predominantly influence the Erosion Wear. Pure glass-polyester composite without filler shows greater Erosion rate whereas a significant improvement in the Erosion resistance is observed with alumina fillers. This may be due to restriction of fiber-matrix debonding. The morphologies of the eroded surface are examined by a scanning electron microscope. Finally, optimal factor settings for minimum Wear rate have been determined using genetic algorithm.

Erosion Wear behavior of coir fiber reinforced epoxy composites filled with al2o3 filler
Journal of Industrial Textiles, 2017Co-Authors: Sandhyarani BiswasAbstract:Now-a-days, natural fibers have been receiving considerable attention as the substitute for synthetic fiber reinforcement in plastics. Among various fibers, coir is the most widely used natural fiber due to its advantages like easy availability, low cost, low density, low production cost and satisfactory mechanical properties. Fiber-reinforced polymer composites often have to function in severe erosive environment in which they encounter solid particle Erosion. To this end, an attempt has been made in this paper not only to study the utilization potential of coir fiber in polymer composites, but also to study the effect of various parameters on Erosion Wear performance of coir fiber-reinforced epoxy composites filled with Al2O3 filler. Twenty different composite samples were prepared with different length (3 mm, 6 mm, 9 mm, 12 mm, and 15 mm) and content (5 wt%, 10 wt%, 15 wt% and 20 wt%) of fiber using hand lay-up technique. The Erosion Wear of these composites has been evaluated at different impingement ...

The coatings are investigated to know their morphological behavior and Erosion Wear characteristics. Plasma spraying is done at different plasma arc current like 200, 250, 300 and 400 amperes. Torch input powers maintained as 6, 9, 12 and 16 KW. The substrates chose are rectangular in shape having a dimension of 50 mm × 25 mm × 2 mm. commercially available aluminum, copper, mild steel and stainless steel being used as substrate. Room temperature solid particle Erosion trials are carried out using a compressed air blasting type rig under impact angles of 30o, 60o and 90o. The present investigation uses an Erosion apparatus of Sand Blast type. The test is conducted as per ASTMG-76 standards. It is analyzed that initially the cumulative coating mass loss increases rapidly and later on becomes almost stagnant. A transient regime in the Erosion process exists, during which the incremental Erosion rate decreases monotonically down to a steady state Erosion rate.

mechanical properties and Erosion Wear resistance of polyurethane matrix composites
Wear, 2005Co-Authors: R. Zhou, Dehong Lu, Yehua Jiang, Q. N. LiAbstract:Abstract In this paper, polyurethane matrix composites reinforced with aluminum oxide (Al2O3) particles were fabricated to improve the Wear resistance of polyurethane (PUR) elastomer working in Erosion conditions, the effects of Al2O3 content (0–64 wt%) and different silane coupling agents (i.e. A-1100 and A-187) on the mechanical properties and Erosion Wear resistances of the composites were investigated. Both the tensile strengths and the elongations at rupture of the composites were found to decrease with the content of Al2O3 particles; however, the hardness increased gradually. The composites treated with silane coupling agent A-1100 had higher tensile properties (tensile strength and elongation at rupture) than those treated with silane coupling agent A-187. Erosion tests were carried out on a self-made jet Erosion machine. According to the results, the Wear resistances of the two composites first increased until reaching a maximum, then decreased, with the increasing content of Al2O3 particles. The composites treated with silane coupling agent A-1100 had higher Wear resistances than those treated with silane coupling agent A-187 due to the higher reaction activity of A-1100 with the matrix than A-187. The fracture surfaces and Erosion area of the composites were analyzed with scanning electron microscope (SEM) and the Erosion Wear mechanism for the composites was discussed.

Fiber-reinforced polymer composite materials with high specific strength and excellent solid particle Erosion resistance
Wear, 2010Co-Authors: Danna Qian, Masayuki Takatera, Limin Bao, Kiyoshi Kemmochi, Atsuhiko YamanakaAbstract:It has been reported that reinforcement fiber such as carbon fiber (CF) and glass fiber (GF) can enhance the strength of polymer composites, but reduce the particle Erosion resistance of the polymer composites. In our study, organic high-polymer fibers (Dyneema®and Zylon®) were used as reinforcement to make fiber-reinforced polymers (FRPs). Tensile tests and particle Erosion Wear tests under various impact angles were carried out for comparison with carbon-fiber-reinforced polymer (CFRP), glass-fiber-reinforced polymer (GFRP), and unsaturated polyester (UP) resin. The damaged surfaces of the Dyneema-fiber-reinforced polymer (DFRP) and Zylon-fiber-reinforced polymer (ZFRP) were analyzed with a scanning electron microscope, and the Erosion Wear mechanisms of the composites were discussed. It was concluded that it was feasible to develop the FRP materials with low density, high strength, and excellent particle Erosion resistance. © 2009 Elsevier B.V. All rights reserved.
