ABSTRACT:
A method for validating the ordering of sequential plies in a laminate having a preselected geometrical configuration increases ease of assembly, visual validation and maintenance of a hard record of validation. The technique may readily be implemented by computer aid design techniques. A preliminary pattern is first produced in the desired configuration of the laminate. This preliminary pattern is indexed by selecting an origin location on its perimeter and placing an index marker thereon to define a working pattern. Working patterns for each sequential ply are produced from the first working pattern with the index marker being sequentially shifted along the perimeter in a selected direction away from the origin. A ply is then produced according to each working pattern, and the plies are assembled so that the index markers form an ascending stair step configuration. Preferably a trim boundary is placed on the preliminary pattern as an intermediate step and the index markers are formed as extensions of the trim boundary. After assembly, the article is trimmed to remove the trim boundary thus allowing for cutting error and providing a record of the validation.
