Hi all
New around here and loving the wealth of knowledge! I have a project I'm looking at which involves threaded inserts in to the end of a carbon fiber tube and am wanting some advice. I haven't worked with cf before but have experience with metals and alloys so please correct me if my rational is way off 🙂
Plan is to have a knurled 6061 aluminum insert with interference fit pressed into the tube ends and use Araldite 2015 as the bonding epoxy between the two. Now for the Q's -
1. What's the best knurl profile? Cross hatch, 45* / course, medium or fine for the OD of the insert against the wall of the carbon fiber?
2. How would the tube wall hold up to an interference fit? Should I worry about splitting? When I say interference it is 16mm OD insert to 16mm ID tube.
3. Shouldd I ream out the tube a little more and apply more epoxy?
Is there there any other considerations I might be missing?
Thanks all 👍
