Fibre reinforcements are materials used to enhance the mechanical properties of composite materials, providing strength, stiffness, and durability. These fibres, typically made of glass, carbon, aramid, or natural materials, are embedded within a matrix such as plastic, resin, or metal to form a composite structure. The fibres align to bear load and resist stress, improving the material's overall performance. Fibre-reinforced composites are widely used in industries like aerospace, automotive, and construction due to their lightweight and high-strength characteristics.
