Difference Between Metals Ceramics And Polymers

There are other material ranges as well but here in this article most common are being discussed.

Difference between metals ceramics and polymers.

Materials can be majorly classified in five considerable categories i e. Creep is a time dependent factor due to. Metals polymers wood fabrics and ceramics. Concrete and plywood are other familiar composites.

Therefore this property of the polymer is highly advantageous because we can replace metal with plastic. As nouns the difference between polymer and ceramic is that polymer is organic chemistry a long or larger molecule consisting of a chain or network of many repeating units formed by chemically bonding together many identical or similar small molecules called monomers a polymer is formed by polymerization the joining of many monomer molecules while ceramic is. Polymers exhibit viscoelasticity at temperatures between where elastic and liquid like behaviors are prevalent. 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. Fiberglass a combination of glass and a polymer is an example. 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. Normally the components can be physically identified and exhibit an interface boundary between one another. Metal matrix and ceramic matrix composites.
