Recycling of CF-ABS machining waste for large format additive manufacturing Compos. Part B Eng. (IF 13.1) Pub Date : 2024-02-09 Roo Walker, Matthew Korey, Amber M. Hubbard, Caitlyn M. Clarkson, Tyler Corum, Tyler Smith, Christopher J. Hershey, John Lindahl, Soydan Ozcan, Chad Duty
Large format additive manufacturing (LFAM) necessitates the use of short fiber thermoplastic composites, such as carbon fiber filled acrylonitrile butadiene styrene, to enable printing. Currently, when LFAM parts are machined into their final shape, the machining scrap ( small flake like particles and offcuts) is landfilled. Previous studies have demonstrated the viability of recycling end-of-life

Reformable and sustainable thermosetting carbon fiber composites from epoxy vitrimer Compos. Part B Eng. (IF 13.1) Pub Date : 2024-02-08 Philip R. Barnett, Justin A. Brackenridge, Abigail A. Advincula, Laine A. Taussig, Dhriti Nepal
Vitrimers are an emerging class of thermosetting materials that undergo reversible dynamic covalent bonding to enable thermoplastic-like repair, joining, and recycling that is currently inaccessible to traditional thermosets. This work demonstrates the production of sustainable recycled carbon fiber/epoxy based vitrimer composites. A method of preparing B-staged vitrimer films enabled infusion of the

Bio-based pH-responsive microcapsules derived from Schiff base structures for acid rain protection Compos. Part B Eng. (IF 13.1) Pub Date : 2024-02-08 Qin Chen, Haonan Zhang, Cheng Hao, Limin Guo, Long Bai, Jiyou Gu, Ning Yan
Self-healing technology based on microcapsules (MCs) holds great promise for preventing material performance deterioration, extending material lifespan, and reducing maintenance costs. In this study, a novel pH-responsive MC with a vanillin-based Schiff base polyurea shell and an isocyanate core was successfully prepared using interfacial polymerization. Vanillin-based Schiff base-containing triamines

Compatibilization of ultra-high molecular weight polyethylene (UHMWPE) fibers and their composites for superior mechanical performance: A concise review Compos. Part B Eng. (IF 13.1) Pub Date : 2024-02-06 Daksh Shelly, Seul-Yi Lee, Soo-Jin Park
In the industrial sector, ultra-high molecular weight polyethylene (UHMWPE) fibers are often recognized as superlative reinforcement owing to their unmatchable characteristics like impressive toughness, exceptional weight-to-strength ratio, low density, excellent wear, and chemical resistance. The remarkable features of UHMWPE fiber/polymer composites have gained substantial attention, rendering them

Stability of crystallographic texture and mechanical anisotropy toward Al2O3/YAG eutectic ceramic composite using single crystalline seeds Compos. Part B Eng. (IF 13.1) Pub Date : 2024-02-06 Yuan Liu, Haijun Su, Xue Tan, Zhonglin Shen, Xiang Li, Hao Jiang, Di Zhao, Yinuo Guo, Zhuo Zhang, Min Guo
During the directional solidification of AlO-based eutectic ceramic composites, crystallographic orientation control is a promising method for tailoring the performances of composite parts. However, despite its importance in the fabrication of texture-controlled structural parts, the stable growth of the eutectic crystallographic texture for long distance (growth distance from 30 mm to 120 mm) in ceramic
