用紫外光固化复合材料制备充气展开器件的研究

系统研究了8种热固化剂的固化工艺条件对环氧树脂／玻璃布预浸料经预热固化、紫外光固化的影响。研究结果表明，采用70酸酐为预热固化剂、碘鎓婧盐为光引发剂，用玻璃布／环氧树脂预浸料制成的空间充气展开器件，经预热固化后，具有较好的柔顺性，表面不发粘，有较长的贮存期，能堆叠成很小体积，在充气展开后经紫外光固化照射能迅速光固化，光固化后的复合材料具有较好的力学性能和尺寸稳定性，能满足空间充气展开技术的要求，从而为紫外固化复合材料在空间充气展开技术中的应用找到了一条新的途径。

A Study on Fabrication of Space Inflating Structure with UV-curable Composite

The influence of molecular structure and curing technology of eight thermal curing agents on the flexibility, surface adhesiveness and UV-curing process of the procured glass-cloth/epoxide prepreg is investigated.Space inflating structure using an glass-cloth/epoxide prepreg with 70-Anhydride as thermal curing agent and diaryliodonium as UV-curing agent is fabricated. After thermal precuring, this structure is flexible with low surface adhesiveness, long storage life and can be pressed to a small volume. After air inflating, such a composite structure could be shortly cured under UV-light to achieve good mechanical properties and dimension. The research results show that this method is suitable for the fabrication of space inflatable structure.
