Document Type and Number:
Japanese Patent JP2021025148
Kind Code:
A
Abstract:
To suppress the generation of wrinkles on a border between a body part and a flange part.SOLUTION: A crossing angle between first continuous yarn 13 and second continuous yarn 14 arranged in a first flange part 24 is defined as a first flange crossing angle θ1. A crossing angle between the first continuous yarn 13 and the second continuous yarn 14 arranged in a second flange part 25 is defined as a second flange crossing angle θ2. A virtual line extending in a direction perpendicular to a first rear face 21a from a first curvature end part P1 is defined as a first virtual line L1. A crossing angle between a first flange edge part 26 and the first virtual line L1 is defined as a first virtual crossing angle γ1. A virtual line extending in a direction perpendicular to a second rear face 22a from a second curvature end part P2 is defined as a second virtual line L2. A crossing angle between a second flange edge part 27 and the second virtual line L2 is defined as a second virtual crossing angle γ2. In a fiber structure 11, following equations are established: γ1+γ2=180°-θ, θ1=90°-γ1, and θ2=90°-γ2.SELECTED DRAWING: Figure 2
