Composite

A composite is a structured material made of two or more chemically or physically distinct components – typically reinforcing fibers and a matrix – whose properties complement each other synergistically, resulting in a material that achieves performance characteristics that the individual components cannot provide on their own. The history of composites dates back to ancient civilizations, where sun-dried bricks reinforced with straw or composite bows were already used; modern composites emerged in the 20th century (e.g., bakelite, fiberglass). The production of composites involves combining reinforcing fibers (glass, carbon, aramid, or natural fibers) with a matrix made of polymers, metals, or ceramics through processes such as molding, pultrusion, or layering. The result is a material with low weight, high strength, stability, and high resistance depending on the chosen components; its properties can be precisely engineered according to the intended application. In the textile industry, composites are mainly used in technical textiles, reinforcement applications (e.g., protective clothing, automotive and aerospace components), hybrid fibers, and smart textiles – where they combine comfort, lightness, and safety in advanced applications.
