Abstract:
1. A process for manufacturing fiber-on-end material, comprising the sequential steps: a) providing a consolidated, shaped billet comprising thermally fused fibers on end, b) cutting trapezoidal sections from the billet such that the fibers are oriented substantially perpendicular to the base of the trapezoidal section, c) welding the trapezoidal sections together to form a billet that is two concentric polygons in cross-section, by: heating in an oven with or without pressure, hot plate welding, vibration welding, or ultrasonic welding, d) mounting the billet formed in step c on a spindle, e) continuously rotating the billet, and f) skiving fiber-on-end material of a desired thickness from the continuously rotating billet.
