Composites and nanomaterials represent a rapidly advancing area of materials science, offering unique combinations of properties that are unattainable in conventional materials. Composites are engineered materials made by combining two or more constituent materials with significantly different physical or chemical properties, resulting in a material with enhanced mechanical strength, lightweight nature, corrosion resistance, and thermal stability. Nanomaterials, characterized by their nanoscale dimensions (typically less than 100 nm), exhibit exceptional surface area, reactivity, and quantum effects that lead to remarkable electrical, optical, mechanical, and catalytic properties. The integration of nanomaterials into composite matrices leads to the development of nanocomposites, which are increasingly used in diverse fields such as aerospace, automotive, biomedical, energy storage, and electronics. These advanced materials can be tailored at the molecular or atomic level to achieve desired functionalities, making them ideal for next-generation technologies. The synergy between nanotechnology and composite science is opening new pathways for designing high-performance, multifunctional materials that address critical challenges in modern engineering and industry.
