Working with 3K fabric
The weave is the trade: plain weave is the most stable and holds its shape when cut; twill and satin conform better to curves (FAA Figure 7-5). With no warp marking, the handbook defaults 0° to the direction the fabric comes off the roll (p. 7-3).
Carbon is gray or black, needs lightning protection on exposed skins, and is cathodic to aluminium; titanium or stainless fasteners are the norm (see repair materials).
Limits — when NOT to use this
- Dry fabric weights, not ply thickness.
- One manufacturer’s data.
- SRM first. Ply count and orientation come from the repair manual.
