Composite cylinders rely on what kind of materials for their construction?

Composite cylinders are specifically designed to utilize advanced materials for enhanced strength and lightweight properties. The correct answer highlights that these cylinders are made from fiberglass or carbon fiber combined with a plastic resin. This combination offers significant advantages over traditional materials, such as increased resistance to corrosion, reduced weight, and improved overall durability.

Fiberglass and carbon fibers provide the structural integrity required to safely contain liquefied petroleum gas, while the plastic resin acts as a matrix that binds the fibers together, ensuring that the cylinder maintains its shape and strength under pressure. This makes composite cylinders particularly suitable for applications where performance and safety are critical.

Understanding the material compositions is essential for recognizing why composite cylinders are preferred in many situations over those constructed from steel or other traditional materials. While other options mention combinations of metals or ceramics, these do not accurately describe the composite technology specifically used in the construction of LP-gas cylinders.
