Abstract
Official abstract text for this publication.
An area of a structure is reworked using resin infusion of a fiber preform. A resin flow hole is formed through the structure from a first side of the structure to a second side of the structure. The fiber preform is placed on the first side of the structure and substantially saturated with resin by flowing resin into the preform and out through the resin flow hole to the second side of the structure.
First claim
Opening claim text (preview).
What is claimed: 1. A method of reworking an area, known as a rework area, of a structure having a first side and a second side, comprising: forming a resin flow hole through the structure in the rework area, from the first side of the structure to the second side of the structure; placing a fiber preform on the first side of the structure, the fiber preform comprising multiple plies; placing a vacuum bag over the fiber preform; sealing the vacuum bag to the first side of th…
