Parametric Optimization Erosion Wear of Polyester-GF-Alumina Hybrid Composites using the Taguchi Method

Abstract

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 Behavior of Glass-epoxy Composites Filled with SiC from Bamboo Leaf

“…Exhaustive literature review on erosion behavior of polymer composites reveal that parameters namely; impact velocity, impingement angle, fiber loading, filler content, erodent size etc. largely influence the erosion rate of polymer composites (Patnaik et al 2008a(Patnaik et al , 2008b(Patnaik et al , 2008c(Patnaik et al , 2008dMahapatra, 2008;Patnaik et al, 2007;Aglan and Chenock, 1993;Harsha et al, 2003;Tamer and Taskiran, 2007;Tewari et al, 2002;Zhou et al, 2005;Rattan and Bijwe, 2007). In the present work, the impact of four such parameters are studied using L9 (3 4 ) orthogonal design.…”

Processing, characterization, and parametric analysis of erosion behavior of epoxy‐LD sludge composites using Taguchi technique and response surface method

“…Various reports are also available on the solid particle erosion wear response of polymer composites filled with ceramic powder such as Al 2 O 3 , SiC, etc. . Taguchi's experimental design has been used to study the wear response of polymer matrix composites by many authors .…”

High-temperature slurry erosion of vinylester matrix composites – The effect of test parameters

“…Thus, the erosion behaviour of a wide range of fibre-reinforced polymer composites with different matrix materials has recently been evaluated. These include glass and carbon fibre reinforced epoxy [3][4][5], polyester [6][7][8][9], polyetheretherketone (PEEK) [10], polyetherimine (PEI) [11,12] and polyphenylenesulphide (PPS) [13], to name a few. Typically, the effect of the reinforcement material, concentration, type and orientation as well as its adhesion to the matrix has been studied in these investigations.…”
