2. What is a Composite Material? A composite material is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. A  composite material  (also called a  composition material  or shortened to  composite , which is the common name) is a  material  which is produced from two or more constituent materials. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from  mixtures  and  solid solutions .

3. Composite materials are generally used for  buildings ,  bridges , and  structures  such as  boat hulls ,  swimming pool panels ,  racing car  bodies,  shower  stalls,  bathtubs ,  storage tanks ,  imitation   granite  and  cultured marble   sinks  and countertops. They are also being increasingly used in general automotive applications. There are various reasons where new material can be favoured. Typical examples include materials which are less expensive, lighter, stronger or more durable when compared with common materials.

4. Composite building material examples include  concrete, reinforced plastics, cement, steel–reinforced concrete, and composite wooden beams . These materials are generally durable and strong. Concrete is the most common artificial composite material of all and typically consists of loose stones (aggregate) held with a matrix of cement. ...

5. Four Types Of Composite Materials: Polymer Matrix Composite’s (PMC’s) is  a composite material composed of a variety of short or continuous fibers bound together by a matrix of organic polymers . PMCs are designed to transfer loads between fibers of a matrix.

6. 2. Metal Matrix Composite’s (MMC’s) a metal matrix composite is a composite material with fibers or particles dispersed in a metallic matrix, such as copper, aluminum, or steel. The secondary phase is typically a ceramic or another metal. 

7. 3. Ceramic Matrix Composite’s (CMC’s) ceramic matrix composites are a subgroup of composite materials and a subgroup of ceramics. They consist of ceramic fibers embedded in a ceramic matrix. The fibers and the matrix both can consist of any ceramic material, whereby carbon and carbon fibers can also be regarded as a ceramic material.  

8. 4. Carbon Matrix Composites (CAMC’s) These composites are  a family of materials which consist of a carbon (or graphite) matrix reinforced with carbon (or graphite) fibres . Thus the attractive properties of carbon are combined with the high strength, versatility and toughness of composites. generally used in aerospace industry for missile nose tips, re-entry heat shields, rocket motor nozzles, and brakes for aircrafts because of its attractive properties like light weight, low density, high strength, stiffness, high thermal conductivity, low  coefficient of thermal expansion, high  fracture toughness , good fatigue, creep resistance, and excellent  thermal shock  resistance.

9. As of M. Knight,  & D. Curliss, composite materials have been introduced into almost every industry in some form or fashion. We shall look at some of the advantages of using composites and discuss some of the industries that have made used of these materials. The wide range of  property  values attained with composites and the ability to tailor the  properties  is an advantage. Composite materials also generally have higher strength- and modulus-to-weight ratios than traditional engineering materials. These features can reduce the weight of a system by as much as 20 to 30%. The weight savings translates into energy savings or increased performance. Advanced composites exhibit desirable  dynamic properties and have high creep resistance and good dampening characteristics.

10. Composites have added new dimensions to the design and construction of buildings. Their ease of manufacture, light weight, high strength, low maintenance, decorativeness, and functionality have had a significant impact on the industry. New-construction time has been reduced and more flexibility has been added to the design of structures. The use of composite materials will continue to grow. As more engineers come to understand composites, more opportunities will be recognized for their use. As the use of composites increases, more developments will take place in the areas of constituent materials, analysis, design, and fabrication. Composite materials offer tremendous for tailorability, design flexibility, and low-cost processing with low environment impact. These attributes create a very bright future composite materials.
