Analyzing the Evolution of Highly Cited Research in Machining of Reinforced Plastics

Introduction

The continual pursuit of lightweight yet high-strength materials has driven substantial research and innovation in the realm of reinforced plastics and composites(Rajak, Pagar, Menezes, et al., 2019) (Boey et al., 2022). The integration of reinforcing agents within polymer matrices has paved the way for a diverse range of applications across industries, including aerospace, automotive, construction, and electronics (Chohan et al., 2022) (Olonisakin et al., 2022). In recent years, the scientific community has witnessed a dynamic evolution of research trends aimed at enhancing the mechanical, thermal, and multifunctional properties of these materials while addressing pressing sustainability concerns. Reinforced plastics and composites, as multifaceted materials, are characterized by their composite nature, wherein a polymeric matrix is fortified with various reinforcement agents, such as fibers, nanoparticles, or natural fillers. This amalgamation capitalizes on the distinct advantages of both components, resulting in materials that surpass the limitations of individual constituents. Consequently, a comprehensive understanding of the underlying principles governing the interactions between the matrix and reinforcement is essential for designing materials tailored to specific performance criteria (Rajak, Pagar, Kumar, et al., 2019) (Seydibeyoğlu et al., 2023). The emergence of advanced manufacturing techniques, notably additive manufacturing and automated fiber placement, has revolutionized the fabrication of reinforced plastics and composites. These techniques offer unprecedented control over material architecture, enabling the creation of intricate geometries and optimized load-bearing structures(Frketic et al., 2017) (Raspall et al., 2019). Concurrently, the exploration of nanomaterials as reinforcement agents has introduced a paradigm shift in material design. Nanoparticles, such as carbon nanotubes and graphene, imbue composites with exceptional mechanical properties, electrical conductivity, and thermal stability (Zhang et al., 2020) (Kumar et al., 2020). Addressing environmental concerns, researchers have embraced sustainable practices by investigating recyclable and bio-based matrices for reinforced composites. This trend aligns with the broader movement toward eco-friendly materials and manufacturing processes (Hanafi et al., 2012) (Jha et al., 2019). Additionally, the integration of natural fibers as reinforcements has garnered attention due to their renewability, low environmental impact, and potential for weight reduction (Nurazzi et al., 2021) (Fuentes Molina et al., 2021). In response to the demands of high-performance applications, the aerospace and automotive industries have gravitated toward reinforced plastics and composites as substitutes for conventional materials like metals. These materials exhibit a remarkable strength-to-weight ratio, rendering them pivotal for enhancing fuel efficiency, reducing emissions, and ensuring structural integrity. The advancement of reinforced plastics and composites is intricately linked with cutting-edge modeling and simulation techniques (Cabrera et al., 2010). Finite element analysis, multiscale modeling, and computational materials science have contributed significantly to unraveling the complex mechanical behavior of these materials under various loading conditions. This computational insight aids in precision engineering and facilitates the optimal design of materials for specific applications. As researchers delve into the durability and long-term behavior of reinforced plastics and composites, insights into factors such as fatigue, creep, and degradation mechanisms are crucial. Understanding these phenomena guides the formulation of materials resilient to extended service conditions, bolstering their reliability and lifespan (Ahmadifar et al., 2022) (Ribeiro et al., 2023).
