Rework System for Composite Structures |
摘要 |
A method and apparatus for reworking a composite structure. A fastener is cooled from a first temperature to a second temperature at which a diameter of a post of the fastener is reduced by a desired amount. The post of the fastener is placed into a channel in a bushing such that a desired interference fit occurs when the fastener is at the first temperature. The bushing with the fastener is positioned in a hole in the composite structure. A gap is present between an outer surface of the bushing and an inner surface of the hole. A gap is also present between an end of the bushing and a second structure. |

1. A system for reworking a composite structure comprising:
a fastener having a post with a first diameter at a first temperature that is greater than a second diameter at a second temperature; a bushing having a channel configured to receive the post, wherein the fastener and the bushing have a desired interference fit when the fastener is at the first temperature; and a cooling system configured to cool the fastener from the first temperature to the second temperature, wherein the bushing with the fastener is positioned in a hole of the composite structure with a gap between the bushing and the composite structure to rework the composite structure. |
