Abstract
A technique for stable, high-speed treatment of reinforcement fiber. In a state where a unidirectional fiber bundle is held between a supporting surface of a support and a pressing surface of a resonator ultrasonically vibrating in a pressing direction perpendicular to the supporting surface, a pressed part of the unidirectional fiber bundle pressed by the pressing surface is moved in a longitudinal direction of the unidirectional fiber bundle. By doing so, the unidirectional fiber bundle can be stably treated at high speed when the unidirectional fiber bundle is opened or impregnated with a resin.

A treatment device for treating reinforcement fiber comprising:
- a support including a supporting surface;
- a pressure body including a pressing surface;
- vibration means for applying ultrasonic vibrations to the pressure body in a pressing direction perpendicular to the supporting surface;
- and
- movement means for moving a unidirectional fiber bundle relative to the pressure body in a state where the unidirectional fiber bundle as the reinforcement fiber is held between the supporting surface and the pressing surface of the pressure body ultrasonically vibrated by the vibration means in the pressing direction, wherein
- the unidirectional fiber bundle is opened while the movement means is moving a pressed part of the unidirectional fiber bundle pressed by the pressing surface in a longitudinal direction of the unidirectional fiber bundle.

- a pressure body including a pressing surface;
- vibration means for applying ultrasonic vibrations to the pressure body in a pressing direction perpendicular to the supporting surface;
- and
- movement means for moving the reinforcement fiber and a resin member relative to the pressure body in a state where the reinforcement fiber overlapped with the resin member is held between the supporting surface and the pressing surface of the pressure body ultrasonically vibrated by the vibration means in the pressing direction, wherein
- the reinforcement fiber is impregnated with a resin of the resin member while the movement means is moving a pressed part of the reinforcement fiber pressed by the pressing surface.
