1. A method comprising:
- identifying a desired shape of a ply on a tool, in which the ply has a fiber orientation;
identifying a cut shape for the ply, in which the cut shape is different than the desired shape;
cutting a composite prepreg ply to have the cut shape, the composite prepreg ply having the fiber orientation;
applying the composite prepreg ply having the cut shape over a deformable carrier;
deforming the composite prepreg by stretching the deformable carrier, stretching comprising changing one of a length or a width of the deformable carrier; and
using deformable carrier to apply the composite prepreg ply having the cut shape to the tool such that the composite prepreg ply has the desired shape on the tool.
