What Are Mechanical Metamaterials?
An Innovative Foundation
Mechanical metamaterials are engineered composites designed with a microstructure that grants them extraordinary properties not typically found in traditional materials. The essence of double-network mechanical metamaterials lies in their unique architecture, combining two interpenetrating networks to optimize mechanical performance.
The Dual Structure
First Network: Traditionally, the first network is a rigid framework composed of various polymers or metals that provide structural integrity.
- Second Network: In contrast, the second network is often softer and elastic, allowing for enhanced flexibility and energy absorption.
This synergistic combination yields materials that demonstrate exceptional strength, toughness, and flexibility, making them suitable for a breadth of applications.
