“…This may be attributed to the combined effect of the cautioning provided by epoxy material along with the high strength provided by the reinforced carbon fibers. 27 Due to cautioning effect provided by the epoxy material, the impacting erodent particles might have a tendency to get bounced back and, on their way, they might have interacted with the incoming erodent particles and may deviate their path, which might have further led to decrease in erosion rate. Also, the presence of high-strength carbon fiber in the adhesive coating may have reduced the tendency of crack formation caused by the impact of erodent particles.…”

“…Fiber-reinforced composites have been widely used for various sectors such as aviation, transport, storage vessel, real estate and marine due to its unique properties such as high specific strength, high modulus, design flexibility in comparison with conventional metal counterparts. 26,27 Furthermore, carbon fibers are used as reinforcement in polymer composites due to benefits associated with its use such as high strength, high-temperature resistance, ease of manufacturing, low specific gravity, low coefficient of friction, light in weight and low wear. 28 Researchers reported that mechanical properties of polymer-based composites are significantly dependent upon loading conditions, fiber dimensions (length and diameter), orientation, and interaction between fiber and matrix.…”

This work presents a novel insight into slurry erosion behavior of thin layer of carbon fiber–epoxy-based composite adhered on 16Cr5Ni steel (adhesive coating) to evaluate its viability as a feasible candidate for slurry erosion applications. Experiments were conducted on a laboratory-developed slurry erosion test rig under accelerated conditions to study the effect erosion parameters namely slurry concentration, impact angle, and impact velocity. Under all the experimental conditions, adhesive coating showed better slurry erosion resistance in comparison with bare 16Cr5Ni steel specimens. Scanning electron microscopy analysis revealed that in the case of bare 16Cr5Ni steel; ploughing, micro-cutting, crater, plastic deformation, and lip formation were identified as main mechanism responsible for slurry erosion, whereas in the case of adhesive coating; pitting, cracking, fracturing, and shearing-off were found to be mainly responsible for material loss. It implies that adhesive coating showed a brittle mode of failure under slurry erosion conditions, whereas 16Cr5Ni steel exhibited a ductile mode of erosion.

“…The experimental sliding wear rate was converted into a signal-to-noise (S/N) ratio. In the present study, the main objective is to minimize the wear rate of the composites and lower the better characteristics approach of the Taguchi experimental design used in the analysis as per Equation ( 3) [22].…”

Reinforcement of metallic and non-metallic particulates will enhance or improve the tribological and mechanicalproperties of metal matrix composites. In the present study, Aluminium 6061 was reinforced with agro-waste based novel Squid Quill Ash (SQA) and Boron Carbide (B4C) by employing a stir casting process. Sliding wear behavior of Al/B4C/SQA hybrid composites investigated by varying SQA content (0.5%, 1%, and 1.5%), sliding speed (400,500 and 600 RPM), and applied load (10,20 and 30 N) using Pin on Disc apparatus. Experiments were performed based on Taguchi L27 orthogonal design. The role of control parameters on wear rate was estimated using the Analysis of variance method. Statastical analysis showed that applied load has a significant effect on the wear rate of the hybrid composites followed by SQA content and Sliding Speed. Material removal during wear test mainly due to the combined effect of formation of cracks, abrasion, and grooves on the target surfaces.

“…The main downside of these methods is the cost and time needed for such experiments if all aspects of real marine environments are to be taken into consideration. The dominant parameters influencing the mechanical properties of composite materials in marine applications are the absorption of seawater [22,23] and the negative effects of polluted process waters from ship systems to constructive materials [24].…”

In this paper, a model for the prediction of fatigue life degradation of fiber-reinforced (FRP) composite materials exposed for prolonged periods to real marine environments is proposed. The data collected during the previous phases of a more comprehensive research of real marine environment-induced changes of mechanical properties in FRP composites are used to assess the influence of these changes on the durability characteristics of composites. Attention is paid to the classification societies’ design and exploitation rules on this matter. The need for the modification of the process used for obtaining composite material S–N curves, considering the influence of the marine environment, is studied. A regression analysis of the experimental data is conducted, resulting in a mathematical model of strength degradation over time. The regression analysis shows an acceptable correlation value. The S–N curves for E-glass/polyester composites with three different fiber layout configurations are evaluated and modified to encompass the findings of this research.
