ABSTRACT:
By the present invention method and apparatus is disclosed whereby a triaxial braided composite reinforcing fabric having axial yarns of varying length may be wrapped about a cylindrical shipping spool without deformation of the braided fabric. A tensioning device is interposed between the braiding tool and shipping or storage spool whereby the individual variable length axial yarns are subjected to constant tensioning. As the braided fabric is wound upon a cylindrical shipping spool, a conformable foam layer is interposed between each layer of braided fabric thereby permitting each axial yarn to seek out its own diameter by compressing the layer of conformable foam upon which it is wrapped.
