Abstract
The adoption of composite materials in commercial aviation has profoundly transformed aircraft design and performance. This research explores the impact of composites, particularly Carbon Fiber Reinforced Polymers (CFRP) and Glass Fiber Reinforced Polymers (GFRP), on aircraft weight reduction, fuel efficiency, and operational performance. By replacing traditional materials such as aluminum, composite materials enable a 15-30% reduction in structural weight, contributing to a 20-25% improvement in fuel efficiency. Models like the Boeing 787 and Airbus A350 exemplify these advancements, achieving enhanced payload capacity, extended range, and reduced environmental impact. Despite challenges such as high manufacturing costs and complex repair processes, the long-term economic and ecological benefits—lower operational expenses and reduced carbon emissions—underscore the importance of composites in sustainable aviation. This study underscores the necessity for further innovation in composite technologies to optimize performance and cost-effectiveness in the evolving landscape of commercial aviation.
