Abstract
Non-standard, resin-infused fiber bundle includes localized regions of fibers having a sub-nominal amount of polymer resin positioned along its length. These regions function as “bending regions,” where the non-standard resin-infused fiber bundle can be readily deformed by virtue of the reduced amount of resin. The bending regions segregate the non-standard resin-infused fiber bundle into what is, effectively, discrete (smaller) segments of (standard) resin-infused fiber bundle. The ability to easily manipulate the non-standard, resin-infused fiber bundle via the bending regions is useful for creating fiber-bundle-based preforms, and preform charges (assemblages of fiber-bundle-based preforms).
