What is the function of fibres in composites?

Fibres in composites serve to enhance the material's mechanical properties, such as strength, stiffness, and toughness. They provide reinforcement, allowing the composite to withstand higher loads and resist deformation. The alignment and type of fibres used can significantly influence the composite's performance, making it suitable for various applications, from aerospace to construction. Overall, fibres are crucial for improving the durability and functionality of composite materials.
