Bladder structure and multilayer bladder system

The invention discloses a bladder structure and a multilayer bladder system. The bladder structure comprises a plurality of walls defining a bladder cavity, and the bladder cavity comprises an initial cross section size. A first plurality of wave features provided along at least one of the plurality of walls defining the bladder cavity. In one arrangement, the first plurality of wave features allow the structure to expand from the initial cross section size to a second cross section size after the structure becomes inflated during composite charge curing processes, the second cross section size larger than the initial cross sectional size. 本发明公开了种囊状物结构及多层囊状物系统，该囊状物结构包括限定囊状物腔体的多个壁，囊状物腔体包括初始横截面尺寸。第多个波纹特征沿限定囊状物腔体的所述多个壁中的至少个壁设置。在个布置中，在所述结构在复合物装料固化期间变得膨胀之后，第多个波纹特征允许所述结构从初始横截面尺寸扩展到第二横截面尺寸，第二横截面尺寸大于初始横截面尺寸。
