Joining titanium plates to carbon by mean of friction
Joining titanium plates to carbon by mean of friction
(OP)
Dear All,
I am designing a link between a carbon web and a couple of titanium plates. Carbon web is in between titanium plates.
I need to transfer trouh the link a big force (i.e. .> 5.0e5N). I am thinking to use bolt preload to develop, by mean of friction, a force that could overcome the external action. Do you have any number for friction coeff. in between carbon and titanium? Any tip for surface preparation?
Best Regards,
Ziller.

I would be concerned about cold-flow and loss of preload.

thanks for the replay, but I probably formulated my question improperly. When I say carbon in reality is composite material.

Would you think of exploring Structural Adhesive Bonding?
The Welding Institute (www.twi.co.uk) have much information and research on the subject.

For surface preparation, I would use a mild solvent to degrease both the titanium and the carbon composite prior to assembly. Isopropanol is common.
