Difference Between Metals Ceramics And Polymers

Concrete and plywood are other familiar composites.

Difference between metals ceramics and polymers. Metals polymers wood fabrics and ceramics. 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. 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. 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. Materials can be majorly classified in five considerable categories i e. Metal matrices offer not only high temperature resistance but also strength and ductility or bendability which increases toughness. Creep is a time dependent factor due to.

Fiberglass a combination of glass and a polymer is an example. Many new combinations include ceramic fibers in metal or polymer matrix. There are other material ranges as well but here in this article most common are being discussed. Some polymers can be stretched up to ten times longer than its original state where metals and ceramics cannot easily accomplish.

Metals polymers ceramics wood fabrics. 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.
