Difference Between Polymers Ceramics And Metals

Concrete and plywood are other familiar composites.

Difference between polymers ceramics and metals.

Composite materials combine two or more materials. 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. Similar to metals and ceramics polymers can experience creep. Many new combinations include ceramic fibers in metal or polymer matrix.

Mention six differences between metals and ceramics yahoo answers free download as pdf file pdf text file txt or read online for free. Metal matrix and ceramic matrix composites. Creep is a time dependent factor due to. Ceramic is a mixture of earth minerals clay and water.

Different materials have different properties. 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. Ceramics are hard and strong but brittle.

Polymers are strong and tough and often flexible. Normally the components can be physically identified and exhibit an interface boundary between one another. Some polymers can be stretched up to ten times longer than its original state where metals and ceramics cannot easily accomplish. Therefore this property of the polymer is highly advantageous because we can replace metal with plastic.

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. 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. Ancient man made pottery and bricks from ceramic clay and ceramic is still used for those purposes today.

Although ceramic is an inorganic material like polymer ceramic is made up of naturally occurring substances and is one of the oldest building and crafting materials known to man. Polymers exhibit viscoelasticity at temperatures between where elastic and liquid like behaviors are prevalent.
