ABSTRACT:
The present invention involves a process that includes injecting a potting compound such as an epoxy through a hollow portion (2B) of the central mandrel (2) and onto the inner layer(s) of a multi-layered fiber bundle (3) and through the outside of the bundle and onto the outer layer(s) of the bundle. By potting through the central mandrel (2), the potting compound distributes evenly throughout the inner fibers of the bundle (3). The steps may be sequentially or simultaneously. Preferably it is done as a two-step process, with the first step being to apply the potting compound through the central mandrel (2) and onto the inner fibers first. The second step is to pot around the outer layer of the fiber bundle (3) to finish the process. The resultant product is also disclosed.
