Lightweight materials such as fiberglass, carbon fiber, and plastic are commonly used in constructing rockets due to their favorable strength-to-weight ratio. These materials allow for reduced overall weight without compromising structural integrity, which is critical in rocketry where minimizing weight can improve performance and fuel efficiency.

Fiberglass offers durability and resistance to environmental stresses, making it suitable for external airframes. Carbon fiber is particularly valued for its exceptional strength and lightness, adding to the vehicle's performance capabilities. Plastic can be used in various components, such as insulation or in parts of the rocket body, benefiting from its versatility and ease of molding into complex shapes.

Other materials mentioned in the alternatives do not align with the best practices in modern rocketry. Heavy metals like steel and lead would contribute significantly to the overall weight, detracting from the rocket's efficiency and performance. While traditional materials like wood and clay have historical significance, they are not practical for contemporary rocketry due to limitations in strength and durability under high-stress conditions. Plastic and rubber compounds may have specific use cases, but they do not offer the comprehensive structural advantages that fiberglass and carbon fiber provide in rocket construction.
