1. 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.
2. 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.
3. Dental composites
• Dental composite resins are types of
synthetic resins which are used in
dentistry as restorative material or
adhesives.
4. Polymer composites
• The term polymer is commonly used today
in the plastics and composites industry,
and it is often used to imply the meaning
of "plastic" or "resin".
• A polymer is chemical compound where
molecules are bonded together in long
repeating chains.
6. 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.
7. 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.
8. 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.
9. 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.
