量化の妨げとなる。However, flexibility and negative pressure resistance are contradictory. In other words, for example, if the wall thickness is made thinner to improve flexibility, the wall thickness becomes thinner, making it easier to deform under negative pressure.Also, by increasing the wall thickness, negative pressure resistance is improved. If the thickness is increased, the thickness becomes thicker, which reduces flexibility and impedes weight reduction.
