F Group: Forum Members Posts: 11, Visits: 18	Hello, Beginner here, I'm trying to put carbon fiber over a block of foam about 1 X 3 1/2 X 6 1/2 inches in size. I thought this would be easy.....but getting it to stick down to the foam and all of the corners....I'm making a complete mess here! Is there an easy way to do this? What am I missing there? Thanks Joe

How did you do the ends of the door?

How do I put carbon over a block of foam?

Getting carbon fibre around corners can be tricky if the corners are too sharp. Often we work with a vacuum bag or similar process where the fabrics are held in place nicely but a hand laid wet type....

that one may gives you the idea https://www.easycomposites.co.uk/learning/cover-parts-in-carbon-fibre-by-skinning EasyComposites use a black epoxy primer coat to glue the cabon fibre on, you ma...

I think some rounding of the edges will help so I'll give that a shot. Wrapping the fabric onto a tacky base coat....that makes perfect sense. I didn't quite understand how he wrapped and created but...

A little thicker base layer makes sense and so does the overlapping joint. How did you do the ends of the door?

Fastskiguy - 5 Years Ago

I did one side at the time with overlapping the fabric on the flanges, then sanding them flat, then coating them The style of the door was like the European doors and frames with double seal I would...

Awesome! A picture is worth a thousand words thanks!! Just one more question....how do I keep the fabric from falling apart when I cut that?

Fastskiguy - 5 Years Ago

You can use masking tape where you need to make cut so something holds fibers in place. Use it on both sides of fabric and remove them before applying epoxy. There are also fabrics especially made....

OK I'll give the masking tape a shot, thanks guys!!

I would suggest to cut is insitio, when putting it on, this was you can press the fabric into the base coat preventing the end from comming out

torstenker - 5 Years Ago

I would cut the fibre while pressing it onto the base coat,the image was only a demo how to overlap you can do multiple sections, does not have to be one piece, that may be better because you cube is...

torstenker - 5 Years Ago

how did you get on with the cube

torstenker - 5 Years Ago

Not good (yet). I picked up some cheap fiberglass and it is more flexible and cheaper while I try to figure out how to do this. It's those damn corners. I need a cube with fewer corners I think ;).....

Fastskiguy - 5 Years Ago

if you make 3 carbon pieces, 1 long one to cover the shorter sides with one long 1" wide strip in one go with opverlapping the corners and and then later cover the top and bottom 6"x3 1/2" sides...

torstenker - 5 Years Ago

A cube is significantly harder to wrap than a surfboard. All about the radius! I would actually suggest not trying to wrap around the corners, but rather try the technique demonstrated in EC's...

Hanaldo - 5 Years Ago

I like both of those ideas....I'm going to try both of them! Thanks guys :)

Fastskiguy - 5 Years Ago

The 6 piece experiment went pretty well but the 3 piece went even better....one large to go around and two small pieces on the ends. Now....do I just grab a sanding block and go to town on those...
