主权项 1. A composite, radius filler noodle comprising: a core having a triangular cross-section configuration and first, second and third surfaces that extend along a length of the core, the core being constructed of unidirectional pre-preg tape that extends along the core length, the core unidirectional pre-preg tape having been pultruded into the triangular cross-section of the core; a plurality of pre-preg fabric first strips stacked on the core first surface, the plurality of first strips having lengths that extend completely along the core length, the plurality of first strips have width dimensions that extend completely across the first surface of the core, the plurality of first strips width dimensions increase as the stack of the plurality of first strips extends away from the first surface of the core to an outermost first strip at an exterior of the composite, radius filler noodle; a plurality of pre-preg fabric second strips stacked on the core second surface, the plurality of second strips having lengths that extend completely along the core length, the plurality of second strips have width dimensions that extend completely across the second surface of the core, the plurality of second strips width dimensions increase as the stack of the plurality of second strips extends away from the second surface of the core to an outermost second strip at the exterior of the composite, radius filler noodle; and, a plurality of pre-preg fabric third strips stacked on the core third surface, the plurality of third strips having lengths that extend completely along the core length, the plurality of third strips have width dimensions that extend completely across the third surface of the core, the plurality of third strips width dimensions increase as the stack of the plurality of third strips extends away from the third surface of the core to an outermost third strip at the exterior of the composite, radius filler noodle.
