The Airbus A350 utilizes a fuselage made of 53% composite materials, reducing fuel burn by approximately 25% compared to previous widebody aircraft. While carbon fiber offers a superior strength-to-weight ratio and resists corrosion, it introduces significant maintenance hurdles. Unlike aluminum, which dents or cracks visibly, carbon fiber can sustain Barely Visible Impact Damage (BVID). This requires labor-intensive ultrasonic testing to detect internal structural failures after hard landings, highlighting the trade-off between operational efficiency and maintenance complexity in next-generation aircraft.
