What are Reinforced Materials?
Reinforced materials are composites that have been strengthened by incorporating materials with superior mechanical properties. In the context of
Nanotechnology, these composites often contain nanoscale reinforcements. These
nanomaterials can dramatically enhance properties such as strength, durability, and thermal resistance.
Types of Nanomaterials Used for Reinforcement
Several types of nanomaterials are commonly used for reinforcing composites:1.
Carbon Nanotubes (CNTs): Known for their exceptional strength and electrical conductivity.
2.
Graphene: Offers outstanding mechanical and thermal properties.
3.
Nanofibers: Provide high surface area and mechanical strength.
4.
Nanoclays: Improve mechanical properties and barrier properties.
5.
Metal Nanoparticles: Enhance electrical and thermal conductivity.
- Load Transfer: Nanomaterials can efficiently transfer loads due to their large surface area and strong interfacial bonding.
- Crack Bridging: They can bridge micro-cracks, preventing crack propagation and thus enhancing toughness.
- Barrier Properties: Nanomaterials can create tortuous paths for molecules, improving barrier properties.
- Thermal and Electrical Conductivity: Their high conductivity allows for improved thermal and electrical properties in the composite.
