They are designed to join two or more dissimilar substances so that they possess properties much more significant than the sum of the individual parts. Primarily, in manufacturing composites, optimization of performance-that is increased strength, durability, flexibility, and resistance to abrasion, heat, or corrosion-is the primary goal. As a result of these outstanding values of strength-to-weight ratio and other characteristic modifications, they have dominated the aerospace, automotive, construction, and sports equipment industries.

The two primary constituents of a composite are the reinforcement and the matrix. The matrix can be any type of polymer, metal, or ceramic that binds the reinforcement and transfers external loads to it. Generally, reinforcement is in the form of fibers and particles; its essential purpose is to impart the material with higher strength and stiffness. Fiber-reinforced composites are the most common kinds, where the material is made from glass, carbon, or aramid fibers that significantly improve the mechanical properties of the composite.

One of the best examples is carbon fiber-reinforced composites. They provide very high strength and stiffness but are in the meantime very light. Thus, these are widely used in aerospace applications where reduction of weight without sacrificing their structural strength is also crucial to improvement and fuel efficiency. Carbon composites are also widely applied for high-performance parts of automobiles, sporting goods, and advanced prosthetics.

PMCs are attractive because of their versatility and ease of manufacture. Applications as diverse as wind turbine blades and medical devices have exploited these materials. Their extremely high-temperature stability makes CMCs an attractive option for jet engine and space vehicle applications.

Bio-composites also composed of natural fibers and biodegradable polymers are increasingly popular because of their ecological friendliness in sustainable engineering and construction ventures.

In conclusion, composite materials play an important role in modern engineering and design, making it possible to develop light, tough, and efficient products. Its versatility continues to push material science endlessly into possibility.
