Recall examples of composite materials. (Chemistry only)

In the subtopic Ceramics, polymers and composites, this learning objective focuses on recall examples of composite materials. (Chemistry only). Within Using materials, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include chemistry only and composite. Carbon fibre reinforced polymer means a composite material consisting of carbon fibres embedded in a polymer matrix, providing high strength and low weight. Avoid students often confuse composite materials with pure substances, thinking they are the same; instead emphasize that composite materials consist of a matrix or binder surrounding reinforcement fibers or fragments, while pure substances contain only one type of material. For exam answers, familiarize yourself with various composite materials and their applications, such as fiberglass and carbon fiber.
