Lightweight refers to materials, products, or systems that are designed to be low in weight while still maintaining strength, durability, or functionality. In the context of research, lightweight materials are a key area of interest for industries such as aerospace, automotive, and construction, seeking to improve efficiency and performance by reducing weight. Research in the field of lightweight materials focuses on developing new materials, technologies, and manufacturing processes that can achieve weight reduction without sacrificing structural integrity or performance. Common lightweight materials include composites, advanced alloys, and polymers. The goal of this research is to create more sustainable, energy-efficient, and cost-effective solutions for various industries.
