Default RE: How to apply carbon veil?


ORIGINAL: saramos

I did some experiments with carbon veil and found there were 2 problems when trying to use it to cover a traditional built up and balsa skinned plane. One you have discovered is that it does not drape well. The other is that it absorbs epoxy like a sponge and leaves a very noticable texture leading to a heavier finish than .5 or .75 oz glass. The light stuff has a lot of voids that need to be filled. I think where it is most used is in vacuum bagging where the pressure helps with both these problems.

That's interesting. I first saw the veil being used as covering in an article about control-line stunt planes. I had thought they were very concerned with weight. Vacuum bagging was not mentioned in the article.

None-the-less, it does look like I need to go back to glass cloth.

Many thanks for all the information.
