There are other material ranges as well but here in this article most common are being discussed.
Difference between metals ceramics and polymers.
The key difference between polymers and metals is that the polymers are lightweight materials compared to metals.
Some polymers can be stretched up to ten times longer than its original state where metals and ceramics cannot easily accomplish.
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.
Metal matrices offer not only high temperature resistance but also strength and ductility or bendability which increases toughness.
Fiberglass a combination of glass and a polymer is an example.
Concrete and plywood are other familiar composites.
Metals polymers ceramics wood fabrics.
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.
Metal matrix and ceramic matrix composites.
Normally the components can be physically identified and exhibit an interface boundary between one another.
Creep is a time dependent factor due to.
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.
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.
