Reinforced polymers are materials made by combining a polymer with a reinforcing agent, such as glass fibers or carbon fibers. This combination enhances the strength, durability, and stiffness of the polymer, making it suitable for various applications, from automotive parts to construction materials. The added reinforcement helps the material withstand stress and strain better than standard polymers. These materials are popular in industries like aerospace and sports equipment, where lightweight yet strong materials are essential. For example, carbon fiber reinforced polymers are often used in bicycles and aircraft to improve performance while reducing weight.
