Metal Polymers Ceramic And Composite

Summary this chapter contains sections titled.

Metal polymers ceramic and composite.

This makes it possible to combine the low weight of the metal with the resistance of ceramics. Advanced polymer metal and ceramic matrix composites show very good potential for applications to aircraft engines and aircraft spacecraft structures over a broad temperature range. Fibers may be in the form of whiskers of substances such as silicon carbide or aluminum oxide that are grown as single crystals and that therefore have fewer defects than the same substances in a bulk ceramic figure 5 6. Ceramic composites like polymer composites ce ramic composites consist of high strength or high modulus fibers embedded in a continuous ma trix.

Metal ceramic and polymeric composites for various uses edited by john cuppoletti composite materials often shortened to composites are engineered or naturally occurring materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct at the macroscopic or microscopic scale within the finished structure. In composite materials made from metal and ceramics a metallic substrate material is reinforced with ceramic hardened particles. Composite materials combine two or more materials. Different materials have different properties.

Ceramics are hard and strong but brittle. Mmcs can be used in such areas as the skin of a hypersonic aircraft but on wing edges and in engines temperatures often exceed the melting point of metals. Polymers are strong and tough and often flexible.
