Fiberglass is best described as a material that consists of what?

Fiberglass is primarily composed of fine filaments of glass that are often combined with resins to create a strong and lightweight material. This composition allows fiberglass to exhibit excellent durability and resistance to corrosion, making it a popular choice for a variety of applications, including construction, automotive, and marine industries.

The use of glass filaments provides the necessary strength and rigidity, while the resin acts as a binding agent that helps to hold the fibers together and provides additional structural integrity. This combination creates a composite material that leverages the benefits of both glass and resin, resulting in a versatile and useful product.

Other materials mentioned in the options, such as wood fibers, plastic filaments, and metal strands, do not accurately characterize fiberglass. Wood fibers are organic and do not offer the same strength-to-weight ratio as fiberglass, plastic filaments represent a different class of materials typically used for distinct purposes, and metal strands do not capture the unique properties of fiberglass, which are essential for its applications. Thus, the best description of fiberglass aligns with the presence of fine glass filaments in resins.
