一种用作飞机壁板的纤维铝锂合金层板及其制备方法
摘要：
本发明提供了一种用作飞机壁板的纤维铝锂合金层板，所述纤维铝锂合金层板由铝锂合金板-纤维预浸料-铝锂合金板依次互相交替铺层通过底胶粘合制成。或由铝锂合金板-纤维预浸料-铝锂合金板-纤维预浸料-铝锂合金板依次互交替铺层通过底胶粘合而成。本发明采用铝锂合金板（2060或2198）为原料制的纤维铝合金层板，用作飞机壁板具有高强度、高抗损伤容限、高静强度等优点，显著降低飞行器的结构重量，增大飞行器的推重比。本发明采用新型的磷酸或硫酸阳极化处理工艺，使层板的制备更加环保。制备方法简单易行，宜于工业化生产，有较大的应用价值。
摘要（英）：

The invention provides a fiber aluminum lithium alloy laminated board used as an airplane wall board. The fiber aluminum lithium alloy laminated board is produced by sequentially and alternatively paving an aluminum lithium alloy board, fiber prepreg and an aluminum lithium alloy board and gluing through bottom glue, or is produced by sequentially and alternatively paving the aluminum lithium alloy board, the fiber prepreg, the aluminum lithium alloy board and the aluminum lithium alloy board and gluing through the bottom glue. The fiber aluminum lithium alloy laminated board is produced by adopting the aluminum lithium alloy board (2060 or 2198) as a raw material, and has the advantages of high strength, high anti-damage tolerance, high static strength and the like when being used as the airplane wall board; the structure weight of an aircraft is obviously reduced and the thrust-weight ratio of the aircraft is increased. According to the fiber aluminum lithium alloy laminated board, a novel phosphoric acid or sulfuric acid anodizing process is adopted so that the preparation of the laminated board is very environment-friendly. The preparation method is simple and feasible, is suitable for industrial production and has a great application value.
