“…Significant improvements in bonded composite patch repair have been seen in the assessment of bonded composite patches [ 13 ]. The Taguchi method is one of the significant approaches to identifying the influenced parameters in any type of linear and non-linear problem, and this can be seen in the experimental work of the glass fibre hybridized flax and sisal fabric hybrid composites to optimize the erosion wear behavior [ 14 ].…”

Over the last four decades, numerous studies have been conducted on the use of bonded composite repairs for aircraft structures. These studies have explored the repair of damaged plates through experimental, numerical, and analytical methods and have found that bonded composite repairs are effective in controlling crack damage propagation in thin plates. The use of double-sided composite repairs has been found to improve repair performance within certain limits. This study focuses on these limits and optimizes double-sided composite repairs by varying adhesive bond and composite patch parameters. The optimization process begins with a finite element analysis to determine the stress intensity factor (SIF) for various variables and levels, followed by the application of the Taguchi method to find the optimal combination of parameters for maximizing the normalized SIF. In conclusion, we successfully determined the stress intensity factor (SIF) for various variations and normalized it for optimization. An optimization study was then performed using the Taguchi design and the results were analyzed. Our findings demonstrate the repair performance of bonded composite patches using a cost-effective and energy-efficient approach.

“…Studies on erosion wear of different materials from metals to polymers and their respective composites are reported extensively in the past two to three decades. The main purpose of these studies has always been to minimize the erosion wear rate and thereby to increase the functional life of the component [7–14]. As far as the use of fiber reinforced composites in wear related applications are concerned, natural fiber composites are being preferred these days over synthetic fiber composites due to their comparable tribological and mechanical properties.…”

This paper aims on evaluating the erosion wear behavior of epoxy composites reinforced with ramie fibers. The possibility of reinforcing ramie fiber to improvise the wear resistance of epoxy is investigated in this study. Composites are fabricated by reinforcing multiple layers of woven ramie fiber mats into epoxy resin using conventional wet lay‐up technique and erosion wear trials are conducted using solid particle erosion test setup. Taguchi analysis is done to assess the relative significance of each of the factors influencing the erosion rate using L16 orthogonal array. The analysis reveals that the impact velocity followed by impingement angle are the most significant control factors affecting the erosion wear rate of ramie‐epoxy composites. Steady state erosion analysis is done to ascertain the effect of each of the significant factors while keeping other factors fixed. Further, an analytical and predictive model based on the principle of neural computation is used to predict the rate of erosion wear of the composites and the obtained results are compared with the experimental outcomes. The worn morphologies of the eroded surfaces of the composites are studied and analyzed to identify possible mechanisms causing wear.

The study aims to evaluate the tensile behavior of sisal glass-reinforced polymer composites with varying geometric irregularities. Composite laminates were fabricated using a hand layup technique, incorporating sisal fiber woven reinforcement and ortho-phthalic unsaturated polyester resin. The laminates, configured with 7 and 9 layers, were subjected to tensile testing with and without 6 mm and 12 mm diameter central holes and double holes spaced at 6.2 mm, 12 mm, and 48 mm intervals. The tensile tests were conducted using an electromechanical test system, and the results were analyzed to determine the ultimate tensile strength, modulus of elasticity, and failure strain for each specimen type. The findings revealed significant differences in tensile strength depending on the presence and size of the holes. Specimens with central holes exhibited a reduction in tensile strength, with the extent of strength reduction dependent on the hole diameter. Larger holes resulted in more severe stress concentrations, leading to greater strength degradation. Double-hole specimens showed similar strength reduction patterns, with closer spacing exacerbating the stress concentration effects. The residual strength ratio (RSR) for different configurations conformed to expected values for fiber-reinforced composites with circular hole-type defects. The study underscores the critical impact of geometric irregularities on the mechanical performance of sisal glass-reinforced polymer composites. These findings can guide the development of design strategies to mitigate the adverse effects of stress concentrators, thereby enhancing the reliability and durability of these materials in practical applications.
