The invention discloses preparation of a large-area self-supporting rigidizable composite film and application of the large-area self-supporting rigidizable composite film in a space inflatable unfolding structure, and belongs to the technical field of space inflatable composite materials. According to the specific scheme, the preparation method comprises the following steps: 1, mixing oxygen heterocyclic resin, an oxygen heterocyclic diluent, a photo-cationic initiator, a free radical thermal initiator, isocyanate and polyol, performing ultrasonic treatment, and then transferring into a vacuum drying oven to remove bubbles so as to obtain a resin mixture; step 2, adding a catalyst into the prepared resin mixture, uniformly mixing, coating the carbon fiber with the mixture, completely infiltrating, and pre-curing at 20-130 DEG C for 0.5-10 hours to obtain a large-area self-supporting stiffened composite film; the large-area self-supporting stiffened composite film wraps the outer portion of the inflatable inner container, local curing is completed through light triggering or heat triggering, large-area, self-supporting and low-energy curing can be achieved through self-maintaining curing, the weight and energy consumption of an extra triggering device are greatly reduced, and the large-area self-supporting stiffened composite film is suitable for a complex and large space inflatable unfolding structure.
一种大面积自支撑可刚化复合薄膜的制备及在空间充气展开结构中的应用，属于空间充气复合材料技术领域，具体方案包括以下步骤：步骤一、将氧杂环类树脂、氧杂环类稀释剂、光阳离子引发剂、自由基热引发剂、异氰酸酯和多元醇混合后超声处理，然后转入真空干燥箱除去气泡得到树脂混合物；步骤二：向配制好的树脂混合物中加入催化剂，混合均匀后涂覆在碳纤维上，并完全浸润，在20‑130℃下预固化0.5‑10h，得到大面积自支撑可刚化复合薄膜；所述大面积自支撑可刚化复合薄膜包裹在充气内胆外部，通过光触发或热触发完成局部固化并通过自维持固化可以实现大面积、自支撑、低能量固化，大大降低了额外触发装置重量和能源消耗，适用于复杂、大型空间充气展开结构。
