ABSTRACT:
A method of providing a structural drop-off in a preplied two or more sheet resin impregnated laminate for forming a composite of several laminates having different structural drop-off positions, each of the sheets having unidirectional fibers oriented at a bias relative to the fibers of the other sheet, and the steps of the method including making a plurality of feather cuts along one edge of the sheets in the direction of the fibers of one sheet and across the direction of the fibers of the other sheet resulting in negligible structural effect on one sheet and foreshortening of the fibers in the other sheet thereby providing a structural drop-off internal to the edge of the preplied two sheet laminate.
