komposiittisina

Komposiittisina refers to the Finnish word "komposiitti," meaning composite. In materials science, a composite is a material made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct at the macroscopic or microscopic level within the finished structure. The goal of a composite material is to create a material that is stronger, lighter, or cheaper than its individual components.

Common examples of composites include fiberglass, carbon fiber reinforced polymers, and reinforced concrete. Fiberglass is made from glass fibers embedded in a polymer resin. Carbon fiber composites consist of carbon fibers in a plastic matrix. Reinforced concrete uses steel bars (rebar) within concrete to improve its tensile strength. The fibers or particles are typically dispersed within a matrix material. The matrix binds the reinforcement together and transfers stress to it.

The properties of a composite material are dependent on the properties of its constituent materials, their proportions, and their arrangement. Composites are designed to achieve specific performance characteristics not attainable by the individual components alone. This allows for the creation of materials with tailored strength, stiffness, toughness, and resistance to environmental factors. Their lightweight yet strong nature makes them valuable in aerospace, automotive, and sporting goods industries.
