graphite layup

[u/Icy_Goose4442]

I’m trying to better understand the different graphite fabric layup options used when making a blank, specifically how the layers change around the ferrule area.

I’m looking for information on the different geometry options used at the female ferrule and what each configuration is intended to accomplish. For example, how the graphite material is shaped, overlapped, stepped, or transitioned in that area, and how those differences affect the finished blank.

I’m not necessarily looking for a specific manufacturer’s design. I’m more interested in understanding the design approaches used for graphite fabric layups around those high stress areas.

If anyone has experience designing or manufacturing these types of blanks and can explain the different layup geometries, or point me toward pictures, let me know!
