Glass fiber or carbon fiber reinforced composites offer advantages of high corrosion resistance and high strength-to-weight ratio than traditional wood or steel materials in yacht making. Thanks to lightness, strength, durability and ease of production the composites play an increasing part in boat construction. Either for interior or for the hull Kordsa may provide different reinforcement materials including glass or carbon UD, 2D and multiaxial impregnated with epoxy. Due to the huge sizes, generally vacuum bag only prepregs (OM12) are recommended.
