The paper "Nanotechnology-Enhanced Fiber-Reinforced Polymer Composites: Recent Advancements on Processing Techniques and Applications" by Adib Bin Rashid, Mahima Haque, S M Mohaimenul Islam, and K.M. Rafi Uddin Labib provides a comprehensive overview of the advancements in nanotechnology-based fiber-reinforced polymer (FRP) composites. The authors discuss the various types of nanoparticles, nanofibers, and nano-coatings used for reinforcement, surface modification, and property enhancement in FRP composites. They highlight the potential benefits of nanotechnology, including improved mechanical properties, surface modification, and sensing capabilities. The paper also examines the challenges associated with incorporating nanotechnology into composites and offers recommendations for future research. The introduction section explains the importance of composites in various industries, such as aerospace, automotive, and biomedical, due to their unique properties like high stiffness, strength, and resistance to environmental degradation. The authors detail the different types of composites, including ceramic matrix, metal matrix, polymer matrix, particle-reinforced, fiber-reinforced, and nano-composite composites. They emphasize the role of reinforcements and matrix materials in achieving these properties. The paper then delves into the processing techniques for nanocomposites, including electrospinning, self-assembly, phase separation, chemical vapor deposition (CVD), and plasma-enhanced chemical vapor deposition (PECVD). Each technique is described in detail, along with its advantages and limitations. The authors also discuss the different types of nanoparticles used for reinforcement, such as carbon-based nanoparticles (e.g., carbon nanotubes, graphene), metal-based nanoparticles (e.g., silver, copper), and metal oxide nanoparticles (e.g., MgO, TiO₂, Al₂O₃, SiO₂, ZnO). They provide examples of how these nanoparticles enhance the mechanical, thermal, and electrical properties of composites. Additionally, the paper explores the use of nanofibers for reinforcement, including carbon nanofibers, graphite nanofibers, polyamide nanofibers, ceramic nanofibers, aramid nanofibers, and cellulose nanofibers. The fabrication methods for nanofibers, such as electrospinning, self-assembly, and phase separation, are discussed, along with their applications in improving the properties of composites. Finally, the paper examines the use of nano-coatings for surface modification of FRPCs, focusing on silica nanocoatings and carbon nanotube (CNT) nanocoatings. These coatings enhance the surface properties of FRPCs, such as scratch resistance, wear resistance, adhesion, and hydrophobicity, further improving their performance in various industrial applications. Overall, the paper provides a detailed review of the current state of nanotechnology in FRP composites, highlighting the potential for future advancements and applications in various industries.The paper "Nanotechnology-Enhanced Fiber-Reinforced Polymer Composites: Recent Advancements on Processing Techniques and Applications" by Adib Bin Rashid, Mahima Haque, S M Mohaimenul Islam, and K.M.
