Difference Between Metals Ceramics And Polymers

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.

Difference between metals ceramics and polymers.

Concrete and plywood are other familiar composites. Metal matrix and ceramic matrix composites. Materials can be majorly classified in five considerable categories i e. Normally the components can be physically identified and exhibit an interface boundary between one another.

Metal matrices offer not only high temperature resistance but also strength and ductility or bendability which increases toughness. Therefore this property of the polymer is highly advantageous because we can replace metal with plastic. Fiberglass a combination of glass and a polymer is an example. There are other material ranges as well but here in this article most common are being discussed.

The key difference between polymers and metals is that the polymers are lightweight materials compared to metals. 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. Creep is a time dependent factor due to.

Metals polymers wood fabrics and ceramics. Polymers exhibit viscoelasticity at temperatures between where elastic and liquid like behaviors are prevalent. Many new combinations include ceramic fibers in metal or polymer matrix.
