    摘要： A turbine component includes an airfoil section elongated in a longitudinal direction; a dovetail section continuous with an end of the airfoil section and bulging in a width direction across the longitudinal direction; a plurality of first reinforcement fibers running continuously from the airfoil section to the dovetail section; a plurality of second reinforcement fibers running at least partly in the width direction in the airfoil section; and a matrix joining an entirety of the first reinforcement fibers and the second reinforcement fibers. In the airfoil section, the second reinforcement fibers are woven into the first reinforcement fibers to form a three-dimensional fabric. In the dovetail section, the first reinforcement fibers are not gathered in the width direction by other fibers but deploy in the width direction.

    摘要： [Object] A design support apparatus, design support method, and program capable of predicting, with good accuracy, a material shape before deformation processing from a 3-dimensional shape model of a product which uses a fiber-reinforced composite material are proposed.
    [Solution] A design support apparatus for supporting designing of a product which uses a fiber material includes a processor that creates a predicted shape model by predicting a shape of the product before deformation processing, wherein the processor: creates a 3-dimensional shape model of the product; creates curved shape models by separating the 3-dimensional shape model into two or more fiber layers; sets a correspondence relationship between the curved shape models; creates an orientation vector field in the curved shape models; and predicts the shape of the product before the deformation processing by developing the curved shape models on a flat surface on the basis of the correspondence relationship between the curved shape models and the orientation vector field in the curved shape models, and creates the predicted shape model on the basis of the predicted shape.
