Difference Between Metals Ceramics Polymers And Composites

Normally the components can be physically identified and exhibit an interface boundary between one another.
Difference between metals ceramics polymers and composites. Creep is a time dependent factor due to. Composite materials combine two or more materials. Fiber flake metal ceramic etc. Concrete and plywood are other familiar composites.
Therefore this property of the polymer is highly advantageous because we can replace metal with plastic. Different materials have different properties. Ceramics are hard and strong but brittle. Some polymers can be stretched up to ten times longer than its original state where metals and ceramics cannot easily accomplish.
The key difference between polymers and metals is that the polymers are lightweight materials compared to metals. Fiberglass a combination of glass and a polymer is an example. 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. Polymers are strong and tough and often flexible.
Similar to metals and ceramics polymers can experience creep. Therefore polymers can play the role as either the filler or the matrix in composites. 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.
Many new combinations include ceramic fibers in metal or polymer matrix. Polymers exhibit viscoelasticity at temperatures between where elastic and liquid like behaviors are prevalent.
