Fiber‐reinforced composites acquire widespread use in the technologically advanced sectors on account of their lightweight and outstanding strength. Considering the significant connection between component quality and durability, bearing strength is a critical factor in the mechanically assembled parts during the manufacturing process. Therefore, in this paper, an experimental study was performed on hybrid glass fiber/aluminum‐mesh composites to assess the impact of abrasive water jet (AWJ) drilling on delamination and bearing strength. The samples were drilled, and the delamination damage was assessed. Finally, the bearing test was conducted on the sample in conformity with ASTM D5961M. The impact of stress distribution on the specimen's failure patterns was studied. Experimental outcomes reveal that the GFA specimen had a 2.9% higher average bearing strength than the AGF specimen. The drilling‐induced damage was determined to be the primary factor responsible for a 27% reduction in bearing strength. The optimization of operational parameters yields improved bearing load and lower damage. A significant level of conformity was detected by the regression accuracy and validation test results with a residual error of less than 10%.Highlights A comparison of two hybrid composites utilizing various layouts for damage and load bearing. Delamination damage is a key factor in predicting the efficiency of bolted connections. Using optimized operation parameters enhances drilling output response significantly.

This paper calculates the crashworthiness capability of glass‐reinforced epoxy composites over wrapped polyvinyl chloride (PVC) circular tubes with a triggering mechanism in the form of cutouts. The intended tubes were prepared by a wet wrapping method; after which they were subjected to quasi‐static axial compression. To compute crashworthiness indications, three design parameters, each at three levels, were used. The design parameters are the hole diameter (d), the hole's number (n), and the hole position (L). The Taguchi technique has been employed in the design of experiments (DOE) tactic to obtain the best crashworthiness parameters. With the maximum specific energy absorbed (SEA) and crashing force efficiency (CFE), the optimal parameters were found. Furthermore, the main effect, signal‐to‐noise ratio (S/N), as well as the analysis of variance (ANOVA), have been studied using the commercial software programme MINITAB 18. A few experiments were accompanied by the L9 orthogonal array. According to the results, “N” has the largest impact on the value of SEA with a contribution percent of 29.27%. While “d” has the main influence on the value of CFE with a contribution percent of 67.29%. Lastly, tests for confirmation were performed. to verify the predicted values in light of the experimental results. The optimized SEA developed tube is 74.72%, which is higher than the intact PVC tube and 12.29% lower than the intact hybrid tube. However, the optimum CFE was also 48 and 29.82% higher than the intact PVC tube and the intact hybrid tube, respectively.Highlights The number of holes has the highest impact on SEA value by 29%. The ideal specimen enhances SEA by 75% compared to the intact PVC tube. Hole diameter has the most influence on CFE value by 67%. The best specimen improves the CFE by 48% related to the intact PVC tube.

“…Other issues with AM products are related to their corrosion and wear performance, or in other words their tribocorrosion behavior, that is induced by the tribological and electrochemical variation of the material due to the presence of voids, pores, molten pool boundaries, surface roughness, and anisotropy. These properties are of crucial importance in the biomedical field since the low wear and corrosion performance may lead to the release of toxic/allergic elements and particles in the periphery of the implant, bacterial inflammation, and finally the loosening and failure of the implant that necessitates second surgeries, incurring a low quality of life and economic costs for patients [26][27][28][29][30][31][32][33]. It has been established that additive manufacturing can significantly change the electrochemical and tribological responses of materials.…”

Today, parts made by additive manufacturing (AM) methods have found many applications in the medical industry, the main reasons for which are the ability to custom design and manufacture complex structures, their short production cycle, their ease of utilization, and on-site fabrication, leading to the fabrication of next-generation intricate patient-specific biomedical implants. These parts should fulfill numerous requirements, such as having acceptable mechanical strength, biocompatibility, satisfactory surface characteristics, and excellent corrosion and wear performance. It was known that AM techniques may lead to some uncertainties influencing part properties and causing significant evaluation conflicts in corrosion outcomes. Meanwhile, the corrosion and wear behavior of additively manufactured materials are not comprehensively discussed. In this regard, the present work is a review of the state-of-the-art knowledge dedicated to reviewing the actual scientific knowledge about the corrosion and wear response of additively manufactured biomedical components, elucidating the relevant mechanism and influential factors to enhance the performance of AM-manufactured implants specifically for the physiological human body fluids. Furthermore, there is a focus on the use of reinforced composites, surface engineering, and a preparation stage that can considerably affect the tribocorrosion behavior of AM-produced parts. The improvement of tribocorrosion performance can have a key role in the production of advanced AM implants and the present study can pave the way toward facile production of high-throughput AM biomedical parts that have very high resistance to corrosion and wear.
