Which of the following materials consists of glass fibres embedded in a polymer resin?

The material that consists of glass fibres embedded in a polymer resin is fibreglass. This composite material is created by combining finely woven strands of glass with a synthetic resin, which serves as a binding agent. The glass fibres provide strength and durability, while the polymer resin adds flexibility and resistance to various environmental factors.

Fibreglass is widely used in various applications, including boat hulls, automotive parts, and insulation, due to its lightweight and high-strength properties. The combination of these two materials results in a versatile and strong product that can withstand significant stress while maintaining a relatively low weight, making it an ideal choice for many engineering and construction projects.

The other choices—chipboard, concrete, and steel—are fundamentally different materials. Chipboard is made from wood particles pressed together with adhesive, concrete is a composite of cement, aggregates, and water, and steel is a metal alloy, typically made from iron with carbon and other elements. These materials do not incorporate glass fibres or polymer resins in their composition.
