Title:
SYSTEM AND METHOD FOR DETERMINING DIRECTION AND SPACING OF FIBER PATHS FOR COMPOSITE PLY
Document Type and Number:
Japanese Patent JP2019038253
Kind Code:
A
Abstract:
To provide a method and a system for specifying one or more fiber angles for each composite ply in a composite laminate in designing the composite laminate.SOLUTION: A method of determining fiber paths for a composite ply includes generating a triangulated surface of the composite ply, and defining a first unit vector field for defining a 0-degree direction for the triangulated surface. A second unit vector field is defined by rotating, through specified fiber angles measured and specified relative to the 0-degree direction, the first unit vector field about surface normals of the triangulated surface. A third unit vector field representing a gradient direction of a potential function is defined by rotating the second unit vector field over 90-degrees about the respective surface normals. A first potential function is determined by performing a least-squares fit such that the direction and the magnitude of the gradient best approximate the direction and the magnitude of a non-unit vector field.SELECTED DRAWING: Figure 1
