Fiberglass is best described as?

• A. Composite structural material of plastic and fiberglass that is used in casting for children and elderly for light weight properties
• B. A fiber glass curtain
• C. A metal mesh
• D. A wood composite

Answer: (A)

Fiberglass is a composite material formed by embedding fine glass fibers in a plastic resin. This combination creates a lightweight, strong, and corrosion-resistant material that is valued for its high strength-to-weight ratio. The description that identifies it as a composite structure of plastic and fiberglass and notes light weight best captures its true nature. The other options refer to things that aren’t fiberglass—an ordinary glass fiber curtain, a metal mesh, or a wood-based composite—so they don’t fit.
