Hi,

I am a begginer in carbon fiber and I am currently facing a problem. I have a mould that is similar to a U shape so when I apply the fist coat of epoxy resin it falls from the almost vertical sides and creates a pool in the middle, is there any tip to make the epoxy resin more viscous so it will not fall down?

Also I would like to include an image in the front cover of the carbon fiber as seen on the picture below. I have tried using lacquer after the carbon fiber part is done and did not work. I tried placing the image as a first layer in the mould before any carbon fiber, but it did not work either since the first epoxy layer did not adhere to the image. Any ideas how can I make this? I was thinking on pasting the image once the carbon fiber part is made and then apply a thick coat of epoxy resin on top of it, but I fear it will drip down and would not leave a uniform layer.

Either using a different resin with a higher viscosity, or pre-reacting a small amount of hardener with your resin before mixing the whole batch and laying it up. The resin will still tend to pool at the bottom.

What material is this picture made of? Some kind of plastic? If there is no adhesion to the epoxy covering it will not work, the epoxy will eventually just flake off.

Printing on thin glass fleece works for text, but usually not for coloured pictures with lots of details.

What works ok is printed paper napkins.
