め、良好な重量バランスが得られ、燃費も向上する。In addition, it is lightweight compared to metal products, and the cross section can be set arbitrarily by increasing the number of ribs in areas that require rigidity or reducing them in unnecessary areas, making it a good product. A better weight balance is achieved and fuel efficiency is improved.
更に、アルミ合金、鋼材等の金属材料に比べて可撓性の
大きい材料が使用できるから、防振性及び衝撃吸収性も
向上できる効果を有する。Furthermore, since materials with greater flexibility than metal materials such as aluminum alloys and steel can be used, vibration damping and shock absorption properties can also be improved.
