Abstract: Composite materials have become a mainstay in modern engineering for their superior strength-to-weight ratios, durability, and versatility. This review covers the developments in composite structures over the last decade, with a focus on recent advances in design and performance optimisation, particularly emphasising sustainability. The primary focus is on hybrid and biobased composites, novel geometric configurations, and advanced manufacturing techniques, including additive manufacturing and automated fibre placement. These further developments enable greater customisation, improved load distribution, and more efficient material utilisation in various industries. The review focuses on performance optimisation in terms of mechanical properties, damage tolerance, and fire resistance. It discusses recent advances in SHM technologies, with a particular emphasis on those utilising embedded sensors and artificial intelligence, which will aid in enhancing damage prediction and durability. Thermal resilience, especially in fire-retardant composites for aerospace, automotive, and infrastructure applications, is also discussed. Besides that, it presents a critical focus on the exploration of lifecycle analysis and current trends in composite recycling or the strategies for EoL. The recycling challenges of thermoset- and thermoplastic-based composites are assessed, along with progress on renewable, lowcarbon composite materials for eco-friendly solutions. This review highlights the significant contribution composites make to reducing emission levels and enhancing energy efficiency across various sectors, including aerospace, automotive, construction, and renewable energy. The study identifies technological and economic challenges and outlines future research directions to promote sustainable advances in composite technologies. Recommendations are presented for industry and policymakers, aiming to facilitate the development of lightweight, high-performance, and environmentally responsible composite materials. This review thus serves as a roadmap for researchers and professionals in the field to tap the full potential of composite materials across diverse applications, addressing design, performance, and sustainability.
