Composites

What’s a composite?

A "composite" is when two or more different materials are combined together to create a superior and unique material. A common

example of a composite is concrete. It consists of a binder (cement) and a reinforcement

(gravel). Adding another reinforcement (rebar) transforms concrete into a three-phase

composite.

Plastics composites

• The plastic substance is a synthetic macromolecular structure, and which is constituted by a large number of molecules of hydrocarbons, alcohols and other organic composites, ie the plastic is an organic substance given the amount of carbon among numerous molecules.

• The plastic may be formed, and is usually formed by the action of heat and pressure either natural and artificial heat and pressure.

Dental composites

• Dental composite resins are types of synthetic resins which are used in dentistry as restorative material or adhesives.

Polymer compositesPolymer composites

• The term polymer is commonly used today The term polymer is commonly used today in the plastics and composites industry, in the plastics and composites industry, and it is often used to imply the meaning and it is often used to imply the meaning of "plastic" or "resin". of "plastic" or "resin".

• A polymer is chemical compound where A polymer is chemical compound where molecules are bonded together in long molecules are bonded together in long repeating chains.repeating chains.

Origen & History

The firts uses of composites date back to the 1500s B.C. when early Egyptians and Mesopotamians settlers used a mixture of ud and straw to create strong and durable building.

Origen & History

Later, in 1200 AD, the Mongols invented the first composite bow. Used a combinations of wood, bone and “animal glue”, bows were pressed and wrapped with birch bark.

Uses

It is uses since S.XX. in the most varied fields: aeronáutica, manufactures of prostheses, astro and cosmonautica,

marine engineering, civil engineering, camping items, etc.

Uses in Odontology.Se utilizan en odontología para obturar dientes. A diferencia de la amalgama de plata, que necesita tener unas cavidades especiales (cavidades de Black) para su obturación, el composite se adhiere micromecánicamente a la superficie del diente sin depender de la cavidad.
