In consideration of the material structure, density, rigidity and weight of the product, as well as the reasonable durability and comfort, each item tests KUOTA's engineers. In 2006, we first applied the carbon fiber nano materials we developed to many existing products, combined multi-level woven fiber aerospace composite materials with nanotechnology, combined with geometric angle structures that do not change too much in shape but contain unique mechanical properties, gave full play to the maximum efficiency of materials, committed to the concept of continuous innovation and development, and made KUOTA products the best choice for competitors in various competitions.
