Polymers Ceramics And Composite Materials

Different materials have different properties.

Polymers ceramics and composite materials.

Ceramics are hard and strong but brittle. Typically most common polymer based composite materials including fibreglass carbon fibre and kevlar include at least two parts the substrate and the resin. Various metals ceramics polymers and composite materials materials include aluminum oxide o r alumina al2o3 silicon dioxide o r silica sio2 silicon carbide sic silicon nitride si3n4 and in addition what some refer to as the traditional ceramics those composed. Polymers are the softest material due to their complex structure while ceramics are the hardest but are not very tough because they fracture before plastic deformation occurs.

This behavior is distinct from the behavior of ceramic fibers in polymer matrix composites pmc and metal matrix composites mmc where the fibers typically fracture before the matrix due to the higher failure strain capabilities of these matrices. Polymers are strong and tough and often flexible. Polymers are strong and tough and often flexible. Polymers plastically deform very easily and have the smallest young s modulus.

Ceramics consist of alumina silica zirconia and other elements refined from fine earth and sand or of synthetic materials such as silicon nitride or silicon carbide. Composite materials combine two or more materials. Polymers are used as film packaging solid molded forms for automobile body parts and tv cabinets composites for golf clubs and aircraft parts airframe as well as interior foams for coffee cups and refrigerator insulation fibers for clothing and carpets adhesives for attaching anything to anything rubber for tires and tubing paints and other coatings to beautify and prolong the life of other materials and a myriad of other uses. Polyester resin tends to have yellowish tint and is suitable for most backyard projects.

Different materials have different properties. Carbon c special silicon carbide sic alumina al 2 o 3 and mullite al 2 o 3 sio. For the latter applications ceramic matrix composites cmcs are seeing increasing use although the technology for cmcs is less mature than that for pmcs. Ceramics are hard and strong but brittle.
