Metals Polymers Ceramics And Composites

Metal matrices offer not only high temperature resistance but also strength and ductility or bendability which increases toughness.

Metals polymers ceramics and composites.

Metals ceramics polymers. Normally they can be differentiable by their. Materials can be categorised as metals ceramics pol. Https engineers academy this video discusses the different classifications of engineering materials.

Different materials have different properties. They are classified according to their physical and chemical structure and properties. 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. Metals are combinations of metallic elements.

Composite materials combine two or more materials. Metals polymers ceramics wood fabrics. Metallic materials have large number of nonlocalized electrons i e. In material science there are basically 3 type of material present in our environment.

Metal matrix and ceramic matrix composites. For every pound of weight reduced on a plane the airline can realize up to 15k per year in fuel cost reduction. Ceramics are hard and strong but brittle. One of the most desired properties of metal alloys is the hardenability.

Alloying can be applied to metals ceramics and polymers where in each specific properties are desired. Fiberglass a combination of glass and a polymer is an example. A material with a high level of hardness will resist deformation caused by surface indentation or abrasion while a material with a low hardness level will deform more easily under similar conditions. A reduction in the weight of parts can have a huge impact on an aerospace company s bottom line.

The same is true for fabrics. Many new combinations include ceramic fibers in metal or polymer matrix. While synthetic fabrics are pure polymers polyamide polyester. Metal ceramic and polymeric composites for various uses edited by john cuppoletti composite materials often shortened to composites are engineered or naturally occurring materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct at the macroscopic or microscopic scale within the finished structure.

Wood is a composite made mainly of cellulose and hemicellulose which are polymers. Many properties of metals are directly attributable to these electrons. Normally the components can be physically identified and exhibit an interface boundary between one another. Polymers are strong and tough and often flexible.
