Fiber-reinforced composites are materials made by combining a polymer matrix with strong fibers, such as glass, carbon, or aramid. These fibers provide enhanced strength and stiffness, making the composite lightweight yet durable. This combination allows for improved performance in various applications, including aerospace, automotive, and construction. The manufacturing process typically involves layering the fibers within the matrix, which can be molded into different shapes. The resulting material exhibits superior mechanical properties compared to traditional materials, making it ideal for products that require both strength and reduced weight, such as aircraft components and sports equipment.
