Difference Between Polymers Ceramics And Metals
The key difference between polymers and metals is that the polymers are lightweight materials compared to metals.
Difference between polymers ceramics and metals. 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. Normally the components can be physically identified and exhibit an interface boundary between one another. Fiberglass a combination of glass and a polymer is an example.
Composite materials combine two or more materials. Similar to metals and ceramics polymers can experience creep. Different materials have different properties. Mention six differences between metals and ceramics yahoo answers free download as pdf file pdf text file txt or read online for free.
Some polymers can be stretched up to ten times longer than its original state where metals and ceramics cannot easily accomplish. Metal matrices offer not only high temperature resistance but also strength and ductility or bendability which increases toughness. Difference between advanced polymers and ceramics and advanced metals. Polymers exhibit viscoelasticity at temperatures between where elastic and liquid like behaviors are prevalent.
Creep is a time dependent factor due to. Ceramics are hard and strong but brittle. The owner of a new car will save 300 gallons 1 100 liters of fuel over the car s lifetime because of the replacement of carbon steel with new high strength lightweight alloys. Concrete and plywood are other familiar composites.
Ancient man made pottery and bricks from ceramic clay and ceramic is still used for those purposes today. Many new combinations include ceramic fibers in metal or polymer matrix. Polymers are strong and tough and often flexible. Metal matrix and ceramic matrix composites.
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. Advanced metals already have begun to make a difference in automobiles.
