So seen this on a mach 2 moth foiler before, admittedly with Twill and UD carbon, but thought I would try to get the name to show through by cutting the letters out the carbon top Twill layer and you see the layer beneath to contrast the top.


This test letter I used hair spray to get the fibre to stay put whilst cutting such detail with a modelling knife, then just hand lay up on a cheap mirror with some peel ply on top and used some West systems 105 and 206 I had hanging around. For the full name I will vacuum and infuse to get a better surface finish.

Any better methods? If I used tape do I need to worry about it being visible or leaving voids? Could I used spray adhesive and stick the carbon onto a fine glassfibre weave to help hold the fibres? I have to do the letters T, N and A. The A will be tricky for the centre part.

Any recommendations on tools or method appreciated.

For things like this i usually use some spray tack to put a thin glass fleece (30gsm) ontop of the fabric. This way you get razor sharp edges and nothing is moving around.
Furthermore i would put the letters as additional layer on top rather as cutout. Exactly the same effect but much easier in terms of handling as you don't have to deal with big patches!

So in this instance you would go glass/carbon/carbon or carbon/glass/carbon?
Ironically never even thought to put the letters on top.

Doesn't really matter too much in this case. I would put the glass against the mould surface i think. Might give you a little more depth.
