Composite T-stiffened skins widely used in aircraft industry nowadays were fabricated by using the co-curing, co-bonding and secondary bonding processes. The stiffener thickness and the tensile property of T-stiffened skins under tensile loading were performed as evaluation indexes to evaluate the manufacturing quality and mechanical property of T-stiffened skins, respectively. The results show that the better manufacturing quality and higher tensile property of T-stiffened skins are found in the co-bonding process, and the tensile property increases with the increase of the adhesive film thickness in the co-bonding process. The co-curing process provides a similar tensile property of the co-bonding process with 0.15 mm thickness adhesive film, but different failure modes in the stiffener/skin interface are found in co-curing and co-bonding processes. Moreover, the filler content and the filler type in the triangle filling area of T-stiffened skins also have significant influence on the tensile property of T-stiffened skins, and rolling adhesive films as fillers into the triangle filling area exhibits the highest tensile property in five kinds of fillers during the co-bonding process.

如今，通过共固化，共粘合和二次粘合工艺可制造出广泛用于飞机行业的T型复合增强蒙皮。以T载荷下的T加强板的厚度和拉伸性能为评价指标，分别评价T载荷下的制造质量和机械性能。结果表明，在共粘合过程中，T形蒙皮具有更好的制造质量和更高的拉伸性能，在共粘合过程中，拉伸性能随胶粘剂膜厚度的增加而增加。共固化过程提供了与0.15毫米厚的粘合膜共粘合过程相似的拉伸性能，但是在共固化和共粘合过程中发现了加劲层/蒙皮界面中的不同破坏模式。此外，T形加硬蒙皮的三角形填充区域中的填充剂含量和填充剂类型也对T形加硬蒙皮的拉伸性能具有显着影响，将填充剂滚动成三角形填充区域的胶粘膜表现出最高的拉伸性能。共粘合过程中的五种填充剂。
