“…As shown in Figure 2, a thermoplastic composite dot matrix structure prepared using a multiple molding process is demonstrated [9]. However, the design of the molds becomes complicated when preparing products with complex three-dimensional structures, and the need to redesign the molds when preparing products that are not mass-produced may lead to the problem of relatively low cost-effectiveness [10,11].…”

“…This is because of deterioration of the CF surface and shortening of their length during the milling, crushing, or grinding processes, which Among the CFRPC management routes mentioned above, the recycling method is an effective one due to the conduciveness of its physical features and its suitable adaptation to management processes. CFRPCs can be recycled using three major techniques, including mechanical, thermal, and chemical processes, at both the academic and industrial levels [4,12,29,30]. Mechanical recycling causes fewer greenhouse gas emissions, which might improve environmental performance compared to other recycling techniques and even to traditional disposal procedures, i.e., landfilling and incineration [31][32][33][34].…”

This review thoroughly investigates the mechanical recycling of carbon fiber-reinforced polymer composites (CFRPCs), a critical area for sustainable material management. With CFRPC widely used in high-performance areas like aerospace, transportation, and energy, developing effective recycling methods is essential for tackling environmental and economic issues. Mechanical recycling stands out for its low energy consumption and minimal environmental impact. This paper reviews current mechanical recycling techniques, highlighting their benefits in terms of energy efficiency and material recovery, but also points out their challenges, such as the degradation of mechanical properties due to fiber damage and difficulties in achieving strong interfacial adhesion in recycled composites. A novel part of this review is the use of finite element analysis (FEA) to predict the behavior of recycled CFRPCs, showing the potential of recycled fibers to preserve structural integrity and performance. This review also emphasizes the need for more research to develop standardized mechanical recycling protocols for CFRPCs that enhance material properties, optimize recycling processes, and assess environmental impacts thoroughly. By combining experimental and numerical studies, this review identifies knowledge gaps and suggests future research directions. It aims to advance the development of sustainable, efficient, and economically viable CFRPC recycling methods. The insights from this review could significantly benefit the circular economy by reducing waste and enabling the reuse of valuable carbon fibers in new composite materials.

“…In the case of FRTPs, it is necessary to use waste materials. The main reinforcement materials used in FRTPs are glass and carbon fibers [ 8 , 9 ]. These fibers are inherently brittle and are often reported to fail due to shear and compression during the melt-forming process [ 10 , 11 ].…”

The mechanical recycling of discarded plastic products as resources for environmental preservation has recently gained research attention. In this context, it is necessary to use waste materials for fiber-reinforced thermoplastics (FRTP). Glass and carbon fibers are often damaged by shear and compression during melt-forming processes. To achieve a sustainable society, it is necessary for thermal recycling to produce minimal to no residue and for mechanical recycling to maintain the length of fibers used in FRTP to preserve their performance as a reinforcing agent. Aramid fibers (AFs) do not shorten during the melt-molding process, and their composites have excellent impact strength. On the other hand, plastics reinforced with glass or carbon fibers are reported to have a superior strength and modulus of elasticity compared to aramid fibers. This study investigates the dispersion of a carbon nanofiber (CNF), a whisker, as the third component in aramid-fiber-reinforced polypropylene (PP/AF). The results and discussion sections demonstrate how the dispersion of CNF in PP/AF can enhance the mechanical properties of injection-molded products without compromising their impact resistance. The proposed composition will have excellent material recyclability and initial mechanical properties compared to glass-fiber-reinforced thermoplastics.
