Study Notes
Material Properties and Applications
- The main restriction on the use of polymers is their limited thermal stability and low resistance to heat.
High-Performance Materials
- Materials with high tensile strength and toughness at moderately high temperatures are typically ceramics or metal matrix composites.
Polymer Benefits
- Polymers are beneficial in many applications due to their low density, corrosion resistance, and ease of processing.
Material Properties Enhancement
- The strength and toughness of materials can be improved through the use of reinforcement, such as fibers or particles.
Composite Materials
- Fibre reinforced plastics and metal reinforced ceramics are examples of composite materials.
High-Temperature Structures
- Ceramics are beneficial for rigid, compressive-load-bearing and high-temperature structures due to their high thermal stability and resistance to heat.
