Abstract: A system and method for fiber-composite part design. A method includes receiving a first fiber orientation field corresponding to a fiber-composite manufacturable part, the first fiber orientation field having a plurality of field rosettes each having a reference point and a corresponding direction vector. The method includes receiving a second fiber orientation field corresponding to the fiber-composite manufacturable part. The method includes identifying a first field rosette in the first fiber orientation field and a second field rosette in the second fiber orientation field that have corresponding reference points on the manufacturable part. The method includes comparing the first field rosette to the second field rosette to identify a fiber orientation difference between the first fiber orientation field and the second fiber orientation field at the corresponding reference point.

Abstract: Apparatus and methods for designing multilayer structures are described. The multilayer structures may be of simple or complex shapes having a volume to be filled by multiple layers of composite material. The composite material may include fiber/polymer composites. The methods facilitate distribution and reordering of layers within the multilayer structure during the design phase. Dimensional data for each layer within the structure may be provided as output data and used to cut “flat” patterns for each layer. The methods and apparatus can accelerate design and development of high-strength, composite multilayer structures.
