Comparison Of Metals Ceramics And Polymers
Normally the components can be physically identified and exhibit an interface boundary between one another.
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. The distortion phenomenon under load in ceramics is also reasonably small as compare to metals. Polymers are strong and tough and often flexible.
Many new combinations include ceramic fibers in metal or polymer matrix. Different materials have different properties. Composite materials combine two or more materials. Ceramic balls are also manufactured to substitute steel in ball bearings.
Metals many similar properties but alloys have very variable strength and melting point 2. Polymers plastics properties very dependent on whether thermosoftening or thermosetting. Fiberglass a combination of glass and a polymer is an example. Copper is a soft malleable and ductile metal with high thermal and electrical conductivity.
The key difference between polymers and metals is that the polymers are lightweight than the metals. Concrete and plywood are other familiar composites. Polymers can experience fatigue under a repetitive loading. Primarily differences are due to their different chemical bonding properties homework 1.
A comparison of four groups of materials. The properties like strength ductility malleability hardness wear resistance and thermal conductivity have varying magnitude for each of metals polymers and 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.
However metals have a lustrous appearance and high thermal and electrical conductivity. Stress strain curves for metals ceramics and polymers objective we are interested about studying and comparing stress strain curves of metals ceramics and polymers. Glass bricks and other ceramics. Moreover the strength to weight ratio of polymer materials is higher than that of metals.
Majorly composed of al 2 o 3 aluminum ceramic is a dense ceramic material with excellent thermal and electrical resistance properties.
