Composite materials

Definition

Composite materials are materials made from two or more constituent materials with significantly different physical or chemical properties. These components work together to produce a material that is superior to the individual components, often combining strengths like lightweight properties and high strength. Their versatility makes them crucial in creating advanced technologies like artificial muscles and new fabrication methods.
