The invention discloses a preparation method and application of a shape memory locking/releasing mechanism, and belongs to the technical field of shape memory composite material preparation, and the preparation method comprises the following steps: step 1, mixing liquid metal with alcohol, and carrying out ultrasonic treatment to obtain an alcohol-liquid metal suspension; 2, coating the alcohol-liquid metal turbid liquid on a left area and a right area of carbon cloth, and volatilizing alcohols to obtain carbon cloth-liquid metal; thirdly, electrodes are led out of the two sides of each liquid metal area; 4, the carbon cloth not coated with the liquid metal and the carbon cloth coated with the liquid metal are stacked together, resin capable of achieving two-stage curing is poured in, and after first-stage curing of the resin is completed, second-stage curing of one liquid metal area is completed; 5, the resin subjected to second-stage curing is heated again, and the resin is bent to lock the structural part I; and the other liquid metal area is bent to be matched with the structural part II, second-stage curing of the area is completed, and the shape memory locking/releasing mechanism is formed.

    一种形状记忆锁紧/释放机构的制备方法及应用,属于形状记忆复合材料制备技术领域,包括以下步骤:步骤一、将液态金属与醇混合并超声处理得到醇‑液态金属悬浊液;步骤二、将醇‑液态金属悬浊液涂覆在碳布的左右两块区域,醇类挥发得到碳布‑液态金属;步骤三、在每一块液态金属区域的两侧均引出电极;步骤四、未涂覆液态金属的碳布与涂液态金属的碳布叠放在一起,倒入可实现二阶段固化的树脂,待树脂完成第一阶段固化后,将其中一个液态金属区域完成第二阶段固化;步骤五、将完成第二阶段固化的树脂再次升温,将其弯折以锁紧结构件Ⅰ;将另一个液态金属区域弯折适配结构件Ⅱ,并完成该区域的第二阶段固化,形成形状记忆锁紧/释放机构。
