Carbon Fiber Patterns Mismatch Type on OEM Aftermarket

[nsxpowered]

I noticed the carbon fiber pattern used on the roof is a Hexcel NC 282 type which is a 3K Plain Weave (1x1).

The interior carbon fiber uses a 3K Twill Weave (2x2). This type of mismatch is usually acceptable because it is exterior vs interior. However I see that BMW OEM used 3K Twill Weave on items like the tailpipe finishers, front splitters, rear spoiler, etc.

Does this seem to bother anyone?

Not at all.

It doesn't bother me at all either.

I think it mainly because of technical reasons they do this. The carbon textiles are very much industrial products and it's difficult to get the perfect finish required on them for the car industry.

Twill fabrics are mainly used on parts where you have sharper edges and more curves. The reason is because it's much easier to drape.

I think BMW use the plain weave on the roof because it's a relatively flat and uncomplex part, and the plain weave creates nice symmetry on a roof.

It's probably not possible for BMW and SGL to make the interior parts or the M performance parts with a plain weaving style at a high enough quality in their process. The plain weaves are actually quite uncommon in the industry.
