... the deviation in orientation of the fibers, in effect creating gores. The locations of darts and splices are critical to the strength of the part and must be approved by stress analysis. Software is available that simulates the draping process and defines the lay-up initiation point and orientation, predicts...

.... Runner channels (“racetracking”): In Fig. 18 a panel with ribs is shown. It can be difficult to drape the reinforcement around the ribs. This will result in a small gap (channel) between the edge of the rib and the reinforcement. This gap will have a high permeability, and resin will flow through...

The process-specific factors that may also play a role include: Fiber volume fraction limitations imposed by the part geometry. These can be determined empirically or estimated with the aid of draping software. Fiber realignment...
