Comparison Of Metals Ceramics And Polymers

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.

Comparison of metals ceramics and polymers. Composite materials combine two or more materials. Primarily differences are due to their different chemical bonding properties homework 1. Ceramics are hard and strong but brittle. Polymers plastics properties very dependent on whether thermosoftening or thermosetting.

Moreover the strength to weight ratio of polymer materials is higher than that of metals. Polymers are strong and tough and often flexible. Different materials have different properties. 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. Copper is a soft malleable and ductile metal with high thermal and electrical conductivity. Polymers can experience fatigue under a repetitive loading. The properties like strength ductility malleability hardness wear resistance and thermal conductivity have varying magnitude for each of metals polymers and ceramics.

A comparison of four groups of materials. However metals have a lustrous appearance and high thermal and electrical conductivity. Composites properties very dependent on the particular reinforcement embedded in the matrix binder. Ceramic balls are also manufactured to substitute steel in ball bearings.

The key difference between polymers and metals is that the polymers are lightweight than the metals. Glass bricks and other ceramics. Metals are a material made up of metallic elements that are bonded metallically like common alloys. The metals polymers and ceramics not only have a different physical appearance but also have variations in mechanical properties.

It is also resistant to corrosion and permeable for microwaves. The higher hardness of ceramics explicates that these are slighter disposed to wear out and can be more durable that steel ball bearings. 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.

Concrete and plywood are other familiar composites.
