Abstract:
A turbine component equipped with: blade parts extending in the lengthwise direction; dovetail parts connected to one end of the blade parts and bulging from the blade parts in the width direction intersecting the lengthwise direction; multiple first reinforcing fibers running continuously from the blade parts to the dovetail parts; a second reinforcing fiber running at least partially in the width direction in the blade parts; and a matrix interconnecting all of the multiple first reinforcing fibers and the second reinforcing fiber.
