ABSTRACT:
The invention relates to methods for making laminate patterns for a resin matrix composite structural component. A sheet of paper (28) is temporarily adhered to a model (26) of the structural component. Pen (13) is positioned on paper (28) with spindle (24) touching the model surface opposite the pen. The pen and spindle are moved along the path that maintains the aforementioned contacts. The resulting line (31) traced on paper (28) is a model constant-thickness locus and provides a pattern for a single lamination of resin-impregnated fabric. The steps are repeated to make other patterns and each time the steps are repeated the distance between the tracer and the spindle is changed to correspond to the thickness of a lamination.
