What is the max thickness for composite material?

2.4.2 At least 85% of the blade by thickness shall be of natural wood; an adhesive layer within the blade may be reinforced with fibrous material such as carbon fibre, glass fibre or compressed paper, but shall not be thicker than 7.5% of the total thickness or 0.35mm, whichever is the smaller.

Basically, if your total thickness is 4.66mm, then your composite layers are at 0.3495mm @ 7.5% total, the maximum thickness allowed.

Take the Viscaria for example, its total thickness is 5.7mm, then the composite layers at max are 0.3477mm @6.1% total.

You can have any number of layers of composite material so long as they are within the above limits.
