“…[ 19 ] This is complemented by their reformability, repairability, and exceptional chemical and aqueous stability, culminating in enhanced recyclability. [ 20 ] In contrast to thermoset prepregs, which are characterized by high reactivity and necessitate cold‐temperature transportation to inhibit curing, thermoplastic prepregs exhibit remarkable stability with an almost infinite shelf life. [ 21 ] This stability significantly simplifies logistics and storage, presenting a more practical solution for manufacturing processes.…”

Over the past 30 years, the polymer composite industry has flourished, producing advanced structural materials for the aviation, energy, and transportation sectors. However, the use of crosslinked thermoset matrices has been linked to significant end‐of‐life challenges, presenting a critical issue for the industry. Moreover, the industry is characterized by numerous labor‐intensive processes. In alignment with Industry 4.0 principles, two major routes have been identified to enhance sustainability: the utilization of high‐performance thermoplastic matrices and the integration of artificial intelligence in manufacturing. Nevertheless, there are substantial concerns regarding the life cycle assessment of these technologies, which are not accounted for in the initial calculations, including the environmental footprint of polymer synthesis and energy requirements for training AI. This perspective aims to address potential and significant CO2 emissions from chemical feedstocks and the high computing requirements of these new technologies.

“…Aramid fiber (AF) is a high‐strength, low‐density, high‐performance fiber utilized in high‐temperature, acidic, alkaline, and abrasive situations. [ 1–3 ] AF is compounded with rubber or thermosetting resin for military, industrial, construction, sports, and other applications. [ 4–7 ] The research on aramid fiber reinforced thermoplastic resin is mainly in the thermosetting composite and some thermoplastic composites such as polyurethane(PA).…”

This study addresses the effect of the coatings prepared from aramid nanofibers (ANFs) on the surface treatment of aramid fiber and reinforced polycarbonate (PC) composite (AF/PC). Aramid fiber's smooth, inert surface bonds poorly with polycarbonate. In this research, the PC‐ANF coating was made by the PC/CH2Cl2 solution, which was modified by aramid nanofibers to improve the interfacial adhesion and compatibility of aramid fiber/PC composites. What's more, the silane (KH570) was added to improve the dispersion and interfacial strength of ANF and PC. The results showed the water contact angle of the aramid fiber modified by PSi‐ANF coating was reduced, indicating the modified fiber has a better wettability. The interfacial bonding strength between PC and aramid fiber increased by 77.2%. The AF/PC composites were prepared by hot‐compression, which the aramid fiber wovens treated with P‐ANF coating, PSi‐ANF coating. The tensile strength, flexural strength, interlaminar shear strength, and impact strength of the AF/PC composite reinforced by AF treated with PSi‐ANF containing 2.0 wt% ANF increased by 62.0%, 81.9%, 49.5%, and 27.6%, respectively. Therefore, this study demonstrates that incorporating ANF interphase may offer an innovative and practical way for enhancing the interface bonding properties of aramid‐reinforced composites.

“…This is observed in dense nonwovens, [26][27][28] in thermoplastics above the glass transition and some thermosets. 29,30 The behavior of a sparsely crosslinked thermoset may exhibit a concave segment, followed by softening and then stiffening, while the same material may be fully brittle when densely crosslinked. In this work we show that inter-fiber cohesion leads to the emergence of this type of behavior.…”
