Comparison Of Metals Ceramics And Polymers

The higher hardness of ceramics explicates that these are slighter disposed to wear out and can be more durable that steel ball bearings.

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

Concrete and plywood are other familiar composites. Normally the components can be physically identified and exhibit an interface boundary between one another. The metals polymers and ceramics not only have a different physical appearance but also have variations in mechanical properties. Composites properties very dependent on the particular reinforcement embedded in the matrix binder.

Primarily differences are due to their different chemical bonding properties homework 1. Polymers plastics properties very dependent on whether thermosoftening or thermosetting. Majorly composed of al 2 o 3 aluminum ceramic is a dense ceramic material with excellent thermal and electrical resistance properties. The properties like strength ductility malleability hardness wear resistance and thermal conductivity have varying magnitude for each of metals polymers and ceramics.

Different materials have different properties. Copper is a soft malleable and ductile metal with high thermal and electrical conductivity. It is also resistant to corrosion and permeable for microwaves. Moreover the strength to weight ratio of polymer materials is higher than that of metals.

Composite materials combine two or more materials. A comparison of four groups of materials. Glass bricks and other ceramics. The distortion phenomenon under load in ceramics is also reasonably small as compare to metals.

The key difference between polymers and metals is that the polymers are lightweight than the metals. 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. Fiberglass a combination of glass and a polymer is an example.

Polymers can experience fatigue under a repetitive loading.
