Erosion analysis of fiber reinforced epoxy composites

Abstract

Lightweight and electrically nonconductive fiber reinforced hybrid epoxy composites have gained attentiveness within specific applications such as marine, automotive and aerospace. However, the components made from these materials can be subjected to significant erosion when they are used in shipping industries and water sports equipment. The present paper proposes to address this challenge by analysing the erosion resistance of glass fiber and silicon carbide (SiC) reinforced epoxy composites. Taguchi's methodology was adopted for the experimentation using the L9 orthogonal array. Impingement angle, erodent type, and workpiece reinforcement were used as input process parameters, whereas erosion loss from the composite was perceived as a response parameter. Regression coefficients and equations for the erosion loss were derived from the regression analysis. The genetic algorithm (GA) was proposed to obtain authentication against Taguchi's methodology. The surface analysis of eroded composites and erodent particles was later evaluated by a Scanning Electron Microscope (SEM). The comparative outcomes achieved from GA and Taguchi's methodology indicates that the angle of impingement and reinforcement size are the primary aspects that affect the erosion resistance of the composite surface.

Solid particle erosive wear behaviour of Eulaliopsis binata fiber reinforced epoxy composite

“…on the erosion rate of the polymer composite. [2][3][4][5] In addition to this, Dalbehera and Acharya 3 along with Antil et al 6,7 studied the additional effect of particulate fillers along with fibers on the erosion behavior of epoxy based composites. The authors are of the view that the addition of particulate filler like SiCp and cenosphere improves the wear resistance of unreinforced fibers.…”

An improvement in drilling of SiCp/glass fiber‐reinforced polymer matrix composites using response surface methodology and multi‐objective particle swarm optimization

“…It is because, during ECDD of the composite at a lower value of the IEG, the formed spark becomes further effective and spark concentration rise with a rise in voltage. [ 6 ] The interaction effect of voltage and DF (Figure 2B) depicts that a higher value of voltage and DF produces spark for longer duration and removes material in high amount. The increase in DF increases the effective discharge frequency and results in increased discharge energy which increases MRR during ECDD.…”

“…[ 5 ] Nowadays, substantial research work has been conducted to improve the machining quality. The researchers have adopted various techniques like Taguchi's approach, [ 6 ] response surface methodology (RSM), [ 7 ] neural networks, [ 8 ] and Gray theory, [ 9 ] genetic algorithm, [ 10,11 ] particle swarm optimization (PSO) [ 12 ] etc. for single and multiresponse optimization of the process.…”
