What are Reinforced Composites?
Reinforced composites are materials made from two or more constituent materials with significantly different physical or chemical properties. When combined, they produce a material with characteristics different from the individual components. In the context of
nanotechnology, these composites are enhanced with nanoscale reinforcements, leading to superior properties.
What are the Benefits of Nanoreinforced Composites?
The addition of nanoparticles to composites offers several advantages:
