Which common material is used for high-power rocket airframes?

High-power rocket airframes are often made from materials like fiberglass or carbon fiber due to their unique properties that align well with the demands of rocketry. These materials provide a high strength-to-weight ratio, which is crucial for rockets as they need to be both lightweight for efficient flight and strong enough to withstand the extreme stresses during launch and flight.

Fiberglass is made of glass fibers woven into a fabric, which is then combined with a resin to create a composite material that is lightweight and durable. Carbon fiber, similar in concept, uses carbon filaments that offer even greater strength and stiffness, making it ideal for high-performance applications where weight savings are critical.

Using fiberglass or carbon fiber also allows for better aerodynamic shaping and reduces the risk of structural failure compared to metals, which can be heavier and more rigid. These properties make these materials particularly popular among high-power rocketry enthusiasts and professionals alike, ensuring optimal performance and reliability during missions.
