Claim Text:
1. A structure comprising: a fiber preform, having a preform diameter, the fiber preform including a fiber matrix material and a continuous layer of filament material having first and second faces and arranged with the fiber matrix material adjacent to each of the first and second faces, the continuous filament material layer having a thickness and a viscosity that enforce breakup of the continuous filament material layer into an array of in-fiber filaments upon drawing of the preform into a fiber; a draw-down region connecting the fiber preform and a fiber; and the fiber, having a fiber length and a fiber diameter that is less than the preform diameter, the fiber including an array of in-fiber filaments extending the fiber length, each filament in the array consisting of the filament material and circumferentially separated from other filaments by the fiber matrix material of the fiber preform.
