Method of making a composite article having an internal passageway |
| 摘要 |
In one particular embodiment, a method for making a fiber-reinforced, composite article having an internal passageway includes providing a layup tool, fiber placing a base layup onto the layup tool, and generating a groove in the base layup. The method further includes placing a mandrel in the groove, fiber placing a top layup onto the base layup and the mandrel, curing the base layup and the top layup, and removing the mandrel from the base layup and the top layup. In another particular embodiment, the mandrel is replaced with a non-removable tube. |
