Comparison Of Metals Ceramics And Polymers

Stress strain curves for metals ceramics and polymers objective we are interested about studying and comparing stress strain curves of metals ceramics and polymers.

Comparison of metals ceramics and polymers.

Concrete and plywood are other familiar composites. Copper is a soft malleable and ductile metal with high thermal and electrical conductivity. A comparison of four groups of materials. Different materials have different properties.

Polymers are strong and tough and often flexible. Polymers plastics properties very dependent on whether thermosoftening or thermosetting. Ceramics are hard and strong but brittle. It is also resistant to corrosion and permeable for microwaves.

The properties like strength ductility malleability hardness wear resistance and thermal conductivity have varying magnitude for each of metals polymers and ceramics. The metals polymers and ceramics not only have a different physical appearance but also have variations in mechanical properties. Metals many similar properties but alloys have very variable strength and melting point 2. Many new combinations include ceramic fibers in metal or polymer matrix.

Composite materials combine two or more materials. However metals have a lustrous appearance and high thermal and electrical conductivity. The higher hardness of ceramics explicates that these are slighter disposed to wear out and can be more durable that steel ball bearings. Primarily differences are due to their different chemical bonding properties homework 1.

Normally the components can be physically identified and exhibit an interface boundary between one another. Metals are a material made up of metallic elements that are bonded metallically like common alloys. They are generally softer than metals and ceramics and unlike metals and ceramics polymer melting occur over a range of temperatures instead at a specific temperature. Majorly composed of al 2 o 3 aluminum ceramic is a dense ceramic material with excellent thermal and electrical resistance properties.

Composites properties very dependent on the particular reinforcement embedded in the matrix binder. The key difference between polymers and metals is that the polymers are lightweight than the metals. Fiberglass a combination of glass and a polymer is an example. Ceramic balls are also manufactured to substitute steel in ball bearings.
