key term - Carbon fiber

Definition

Carbon fiber is a strong, lightweight material made from thin strands of carbon atoms that are tightly bonded together. This material is known for its high tensile strength and rigidity, making it an ideal choice for aerospace applications where performance and weight efficiency are critical. Carbon fiber composites are often used in combination with resins to create structures that can withstand extreme conditions while keeping overall weight low.
