Composite materials have unique advantages over monolithic materials, such as high strength, high stiffness, long fatigue life, low density, and adaptability to the intended function of the structure. Significant achievement has been made in the design/development and applications. Considerable innovative research is still continuing for the development of continuous fibre composites and particulate composites for critical applications. Structural requirements demand ultimate and reliable composite material performance to react to global static and dynamic external and component loads.
