Question
- A. To reduce weight
- B. To improve thermal conductivity
- C. To enhance strength and stiffness
- D. To provide electrical insulation
Answer
The correct option is To enhance strength and stiffness. This answer is correct because it matches the approved learning objective to describe a composite as a matrix or binder surrounding reinforcement fibres or fragments. (Chemistry only) in the subtopic Ceramics, polymers and composites.
Explanation
The correct option is To enhance strength and stiffness. To enhance strength and stiffness is correct because it directly supports the approved learning objective to describe a composite as a matrix or binder surrounding reinforcement fibres or fragments. (Chemistry only). This belongs to the subtopic Ceramics, polymers and composites within Using materials, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Ceramics, polymers and composites.
Common mistake
Misunderstanding Composites
Students often confuse a composite with a single material, thinking it is just one type of substance rather than a combination.
Remember that a composite is made up of a matrix or binder that surrounds reinforcement fibres or fragments, combining different materials to enhance properties.
