“…The mechanical properties were obtained to be less in aged composites, and the retention of tensile and flexural properties was higher in CFRP than GFPR composites. 36 Besides, GFRP pultruded composite was hydrothermally aged at 20, 40, and 60 C for 12 months. The maximum flexural strength retention was obtained for isophthalic polyester GFRP composites and compared with orthophthalic and vinyl ester GFRP composites.…”

Quest to reduce challenges of high structural weight and cost of metallic components is increasing. It has led to their replacement with carbon and Kevlar fibers reinforced polymer (FRP) composites. These aforementioned problems can be further solved through hybridization of carbon/glass (CG) and Kevlar/glass (KG) fibers to reduce the manufacturing cost and materials usage, not at detriment of their properties. Also, investigation into their tensile properties, diffusivity, and service life is germane. Therefore, the present study focuses on influence of hybridization of CG and KG fibers on seawater diffusivity, service life, and tensile strengths of their composite systems, through hydrothermal aging. The hybrid composites were aged in seawater for 50, 150, and 300 days at temperatures of 20, 40, and 60 C. From the results obtained, it was evident that the maximum moisture absorption of both FRP hybrid composites occurred at 60 C in 300 days of hydrothermal aging. The maximum tensile strengths were obtained in unaged composite counterparts. Also, the aged FRP hybrid composites exhibited the lowest tensile strengths at 150 days. The retention of maximum tensile strengths of CG and KG FRP

“…In material science in the previous decade was used mainly "composite" term for characterization of such materials. But having of combination materials from different classes, for example, organic-inorganic [1]; bio-based-rubber [2]; metal-polymer [3]; steel-glass [4,5] the term "hybrid" became more often used to declare nature of the material type. To achieve unique properties or properties combinations researchers pay attention to hybrid materials design: for lightweight ceramic materials [6], lightweight and high-temperature resistant materials [7,8], metalceramic lightweight hybrid materials [9], hybrid polymer matrix composites [10,11], and hybrid metal-based composites [12][13][14].…”

Hybrid additive manufacturing is a relatively modern trend in the integration of different additive manufacturing techniques in the traditional manufacturing production chain. Here the AM-technique is used for producing a part on another substrate part, that is manufactured by traditional manufacturing like casting or milling. Such beneficial combination of additive and traditional manufacturing helps to overcome well-known issues, like limited maximum build size, low production rate, insufficient accuracy, and surface roughness. The current paper is devoted to the classification of different approaches in the hybrid additive manufacturing of steel components. Additional discussion is related to the benefits of Powder Bed Fusion (PBF) and Direct Energy Deposition (DED) approaches for hybrid additive manufacturing of steel components.* e-mail: vvp@technion.ac.il Rev. 7, 6 (2020) This is an Open Access article distributed under the terms of the Creative Commons Attribution License (https://creativecommons.org/licenses/by/4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.

Glass and carbon fiber reinforced polymer hybrid composites are the need of the hour to overcome the weakness of individual fibers. The mechanical and abrasive wear property of the hybrid composites needs to be evaluated to ascertain the feasibility in structural and tribological applications. In this article, hybrid composites of different stacking sequence such as [G 3 C 2 ] S, [GCG 2 C] S and[G 2 C 2 G] S has been designed. The flexural strength and three body abrasive wear resistance of the hybrid composites were evaluated and compared among themselves. It is observed that the flexural strength and modulus of [GCG 2 C] S type hybrid composite was improved by 46.1% and 49.5% respectively as compared to plain glass fiber reinforced polymer composites. The specific wear rate was evaluated by three-body abrasive wear at different operating parameters and optimized the same through response surface methodology. Box-Behnken design of the experiment was adopted to design the experiments. The model has predicted the minimum specific wear rate for [GCG 2 C] S hybrid composite is18.8476×10 -3 mm 3 Nm −1 at applied load of 33.15 N and sliding distance of 1100 m. The model predicted results were compared with experimental one and found a good agreement between them. The worn surface of the composites was analyzed by scanning electron microscope to understand the wear mechanism.
