Comparison Of Metals Ceramics And Polymers

Polymers are strong and tough and often flexible.

Comparison of metals ceramics and polymers.

Majorly composed of al 2 o 3 aluminum ceramic is a dense ceramic material with excellent thermal and electrical resistance properties. The higher hardness of ceramics explicates that these are slighter disposed to wear out and can be more durable that steel ball bearings. Many new combinations include ceramic fibers in metal or polymer matrix. It is also resistant to corrosion and permeable for microwaves.

The key difference between polymers and metals is that the polymers are lightweight than the metals. Copper is a soft malleable and ductile metal with high thermal and electrical conductivity. Composite materials combine two or more materials. Ceramic balls are also manufactured to substitute steel in ball bearings.

Metals are a material made up of metallic elements that are bonded metallically like common alloys. Stress strain curves for metals ceramics and polymers objective we are interested about studying and comparing stress strain curves of metals ceramics and polymers. A comparison of four groups of materials. Ceramics are hard and strong but brittle.

However metals have a lustrous appearance and high thermal and electrical conductivity. Different materials have different properties. Concrete and plywood are other familiar composites. Polymers plastics properties very dependent on whether thermosoftening or thermosetting.

Glass bricks and other ceramics. The distortion phenomenon under load in ceramics is also reasonably small as compare to metals. Primarily differences are due to their different chemical bonding properties homework 1. The properties like strength ductility malleability hardness wear resistance and thermal conductivity have varying magnitude for each of metals polymers and ceramics.

Composites properties very dependent on the particular reinforcement embedded in the matrix binder. Fiberglass a combination of glass and a polymer is an example. Normally the components can be physically identified and exhibit an interface boundary between one another. 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.

The metals polymers and ceramics not only have a different physical appearance but also have variations in mechanical properties.
