Difference between metals ceramics and polymers.

Similar to metals and ceramics polymers can experience creep. The requirement that finished parts be able to operate at temperatures high enough to melt or degrade a polymer matrix creates the need for other types of matrix materials often metals. If we take a ball made of a polymer material such as plastic and a ball made of a metal with the same size we can observe that the metal ball is heavier than the plastic ball. Metal matrices offer not only high temperature resistance but also strength and ductility or bendability which increases toughness.

Polymers exhibit viscoelasticity at temperatures between where elastic and liquid like behaviors are prevalent. Normally the components can be physically identified and exhibit an interface boundary between one another. Concrete and plywood are other familiar composites. Many new combinations include ceramic fibers in metal or polymer matrix.

Materials can be majorly classified in five considerable categories i e. Therefore this property of the polymer is highly advantageous because we can replace metal with plastic. Some polymers can be stretched up to ten times longer than its original state where metals and ceramics cannot easily accomplish.
