Traditional aluminum structures are increasingly being replaced by carbon fiber reinforced composites. These materials offer exceptional strength while significantly reducing weight.

Lower structural weight directly improves fuel efficiency, increases payload capacity, and extends flight range.

Modern aircraft such as the Boeing 787 Dreamliner and Airbus A350 contain over 50% composite materials by weight.

Challenges include manufacturing costs, inspection techniques, and repair procedures.

As production methods become more efficient, composites will dominate future aircraft structures.
