阅读说明：本技术 由三个片材形成的囊状元件和制造囊状元件的方法 (Bladder element formed from three sheets and method of manufacturing a bladder element ) 是由 菲登西奥·坎波斯二世 扎卡里·M·埃尔德 本亚明·J·蒙菲尔斯 于 2016-04-20 设计创作，主要内容包括：本申请涉及由三个片材形成的囊状元件和制造囊状元件的方法。该方法包括使第一(20)、第二(22)和第三聚合物片材(24)中的至少一种形成为具有波状表面轮廓(P)。第一、第二和第三聚合物片材被堆叠成使第二聚合物片材在第一和第三聚合物片材之间。还包括在第一和第二聚合物片材之间、在第二和第三聚合物片材之间、或在第一和第二聚合物片材之间且在第二和第三聚合物片材之间施加流体压力,迫使第二聚合物片材的第一表面与第一聚合物片材的内表面接触,或迫使第二聚合物片材的第二表面与第三聚合物片材的内表面接触,或迫使第二聚合物片材的第一表面与第一聚合物片材的内表面接触并且第二聚合物片材的第二表面与第三聚合物片材的内表面接触。还公开了囊状元件。(The present application relates to a bladder element formed from three sheets and a method of manufacturing the bladder element. The method includes forming at least one of the first (20), second (22), and third polymeric sheets (24) to have an undulating surface profile (P). The first, second and third polymeric sheets are stacked with the second polymeric sheet between the first and third polymeric sheets. Further comprising applying fluid pressure between the first and second polymer sheets, between the second and third polymer sheets, or between the first and second polymer sheets and between the second and third polymer sheets, forcing the first surface of the second polymer sheet into contact with the inner surface of the first polymer sheet, or forcing the second surface of the second polymer sheet into contact with the inner surface of the third polymer sheet, or forcing the first surface of the second polymer sheet into contact with the inner surface of the first polymer sheet and the second surface of the second polymer sheet into contact with the inner surface of the third polymer sheet. A bladder element is also disclosed.)
