• Ceramics are often used in applications where high temperature resistance is required, while metals are often used in applications where strength and ductility are required.

2. What are the different types of composite materials?

• Polymer matrix composites (PMCs): In PMC, the matrix is a polymer, and the reinforcement is a fiber or particle.
• Metal matrix composites (MMCs): In MMCs, the matrix is a metal, and the reinforcement is a fiber or particle.
• Ceramic matrix composites (CMCs): In CMCs, the matrix is a ceramic, and the reinforcement is a fiber or particle.

3. What are the advantages of using composite materials?

• High strength and stiffness: Composite materials can be very strong and stiff, even at high temperatures.
• Lightweight: Composite materials are often lighter than traditional materials, such as metals.
• Corrosion resistance: Composite materials are often resistant to corrosion, making them ideal for use in harsh environments.
