技术领域：Technical field:
本发明涉及一种加强筋壁板共固化成型方法。The invention relates to a co-curing molding method for a rib wall plate.
背景技术：Background technique:
复合材料长桁种类主要包括“工”字桁件；“T”字桁件；“ω”桁件等；桁件预固化，通过整体定位实现桁件与壁板的共固化成型；现有的桁件壁板类零件的共固化成型方法有两种；一种常规的方法是通过金属组合模保证桁件的外形，金属组合模需要与壁板成型模进行可靠的定位，来保证桁件位置的准确性；用于桁件的定位组合模结构复杂，制造精度要求高，加工难度大，导致产品和成型模的成本高；The types of composite long trusses mainly include "I" trusses; "T" trusses; There are two co-curing molding methods for truss panel parts; one conventional method is to ensure the shape of the truss through the metal composite mold, and the metal composite mold needs to be reliably positioned with the panel forming mold to ensure the position of the truss accuracy; the structure of the positioning combination mold used for girders is complex, the manufacturing precision is high, and the processing is difficult, resulting in high cost of products and forming molds;
另一种成型方法是子母真空袋法：将预制好的、类似筒状的柱形真空袋填充到桁件与壁板之间形成的内腔中，在Ω型加强筋的外表面及壁板上铺覆外真空袋，将柱形真空袋外表面与Ω型加强筋的内表面之间的空间和外真空袋的内表面与Ω型加强筋、壁板的外表面之间的另一空间相连接并密封；此方法的优点是：降低成型成本。但对于操作者的技能水平要求高，一旦真空袋漏气，很容易造成零件的报废。Another molding method is the mother-in-law vacuum bag method: fill the prefabricated cylindrical vacuum bag similar to the cylindrical shape into the inner cavity formed between the stringer and the wall plate, and place it on the outer surface of the Ω-shaped rib and the wall. The outer vacuum bag is laid on the board, and the space between the outer surface of the cylindrical vacuum bag and the inner surface of the Ω-shaped rib and the other space between the inner surface of the outer vacuum bag and the outer surface of the Ω-shaped rib and the wall panel The space is connected and sealed; the advantage of this method is: reduce the molding cost. However, the skill level of the operator is high, and once the vacuum bag leaks, it is easy to cause the parts to be scrapped.
