The course on material selection aims to equip students with the skills to choose suitable materials for product design by considering functional, economic, and environmental factors while encouraging creativity. It covers the importance of material selection, including aspects like functionality, durability, aesthetics, and cost, along with an overview of four main material categories: metals, ceramics, polymers, and composites. Additionally, it emphasizes the interplay between material properties, manufacturing processes, and geometry in the design process.

- 1. Course Introduction and Overview of Material Selection By: Prof. Hany M. El-Said
- 2. Course Aims & Objectives Course Aims: • To equip students with the knowledge and skills to select appropriate materials for product design, • considering functional, economic, and environmental factors, • while fostering creativity in material manipulation. Course Objectives: • Understand the principles of material selection in product design. • Evaluate materials based on functional, economic, and environmental criteria. • Explore the relationship between material properties, manufacturing processes, and product performance. • Develop creative approaches to material manipulation for innovative designs.
- 3. Importance of Material Selection in Product Design Why Material Selection Matters: - Functionality: Ensures the product performs as intended. - Durability: Affects the product's lifespan and reliability. - Aesthetics: Influences the visual and tactile appeal of the product. - Cost: Impacts production expenses and environmental sustainability. Key Considerations: - Functional requirements - Processability - Cost (economic and environmental) - Reliability - Resistance to service conditions
- 4. Overview of Material Categories Materials are classified into four main categories, each with unique properties and applications: 1. Metals 2. Ceramics 3. Polymers 4. Composites
- 5. Metals Properties: - High strength and ductility - Good thermal and electrical conductivity Applications: - Structural components (e.g., bridges, buildings) - Machinery and tools - Electrical wiring Examples: - Steel, aluminum, copper, titanium
- 6. Ceramics Properties: - High hardness and thermal resistance - Chemically stable Applications: - Insulators and cutting tools - Biomedical implants - High-temperature components Examples: - Alumina, silicon carbide, zirconia
- 7. Polymers Properties: - Lightweight and flexible - Corrosion-resistant Applications: - Packaging and textiles - Automotive parts - Consumer goods Examples: - Polyethylene, PVC, nylon, rubber
- 8. Composites Properties: - Combination of properties from two or more materials - High strength-to-weight ratio Applications: - Aerospace and automotive industries - Sports equipment - Construction Examples: - Fiberglass, carbon fiber-reinforced polymers, concrete
- 9. How Do We Choose A Material? Product function depends upon… Material, manufacturing process, geometry (MFG) We have to consider all three Do we select a few feasible materials first… Then select the specific MFG processes? Or Do we select a few feasible MFG processes first… Then select the specific materials?
- 11. Design Material Manipulation = Creativity - Material selection is both a technical and creative process. - Understanding material properties and limitations enables innovation. - The interplay between material, manufacturing process, and geometry (MFG) is key to successful design.
