carbon fiber repair/ epoxy question
Hi All - I have a CF hardshell bucket seat for a recumbent bicycle. On
the back of the seat are 2 2" ribs running up and down for support. One of these ribs hit something sharp which left a spidery, crooked, 2" long crack across it (horizontal). I'd like to repair this and am looking for advice from an expert. I'm currently considering using 2" or 3" CF "tape" and SystemThree T-88 epoxy and layering it up with 3 layers, one slightly larger than the other. Does this sound like it will work? Also while we're on the topic: I'm interested in epoxy bonding some .75" OD x .049 wall Al tubing that has been mitered together for a light load bearing application. Should I be using a filler with the epoxy and if so, what kind? Thanks in advance, Chris |

carbon fiber repair/ epoxy question
I have some limited experience with fibre glass and epoxy which I use when
building strip kayaks. The solution for the seat sounds like it should work. The CF tape sounds like over kill. You could probably do it cheaper with 2 layers of glass tape. I would suggest that if you have not worked with epoxy before you practice a bit before you work on the seat. It not difficult it just hslps to know how the stuff behaves so you can plan your work. As for bonding the tubing the only thing I can say on that is try and see. Fillers night help a bit if you use the fibre type rather then something that is just going to add bulk. This is a place the CF tape might help if you plan on doing something other then just glueing them together. Lot of good info here. http://www.oneoceankayaks.com/ http://www.blueheronkayaks.com/kayak/index.html Check out cradles Chris "Chris Crawford" wrote in message news.com...
