Tribo-performance of polyester hybrid composites: Damage assessment and parameter optimization using Taguchi design

Abstract

This paper investigates the solid particle erosion wear performance of a multi component hybrid composite consisting of polyester, glass fibers and alumina particles. A mathematical model for damage assessment in erosion is developed and validated by a well designed set of experiments. For this, the design of experiments approach using Taguchi's orthogonal arrays is used. The study reveals that glass-polyester composite without any filler suffers greater erosion loss than the hybrid composite with alumina filling. Significant control factors and their interactions that influence the wear rate are identified. Finally, optimal factor settings are determined using genetic algorithm.

Tribo-performance analysis of red mud filled glass-epoxy composites using Taguchi experimental design

“…Another model proposed recently by Patnaik et al [8,12] assumes that the kinetic energy of the impinging particles is utilized to cause indentation in the composite surface and the material loss is a measure of this indentation. It also assumes that both the erodent material and the target material are at same temperature and therefore there is no exchange of any thermal energy between them during the impact.…”

“…To this end, an attempt has been made in this study to analyze the impact of more than one parameter and their interactions using Taguchi's parameter design on the erosion wear of the red mud filled epoxyglass fiber composites. Such an approach has been successfully applied for parametric appraisal in the wire electrical discharge machining (WEDM) process, erosion behaviour of polymer-matrix composites [8,[11][12][13][14][15].…”

An Assessment of Erosion Wear Response of SiC Filled Epoxy Composites Reinforced with Glass and Bamboo Fibers

“…5, the role of thermal energy transfer from erodent to target material in causing erosion is absent and thus the expression is similar to the one in the theoretical model proposed earlier by Patnaik et al (2008). The hardness alone is unable to provide sufficient correlation with erosion rate, largely because it determines only the volume displaced by each impact and not really the volume eroded.…”

“…3, is used to assign the factors and interactions to various columns of the orthogonal array by Glen (1993 In design of experiment, the most important part lies in the selection of the control factors. Exhaustive literature review on erosion behavior of polymer composites reveal that factors viz., impact velocity, filler content, impingement angle, standoff distance and erodent size etc largely influence the erosion rate of polymer composites (Patnaik et al, 2008). Hence in the present work the impact of these six parameters are studied using L 27 (3 13 ) orthogonal design.…”
