Use monel rivets, not titanium. You can't easily upset Ti fasteners.
Monel is nickel based and does not corrode in carbon. It is also hard to upset; work hardens.
What are you trying to do that calls for such rivets?

Just one more point on riveting-
Don't use solid rivets in any carbon fiber part because the radial expansion of shank from upsetting will damage hole surface and reduce bearing strength. And don't use alum in direct contact with carbon as it will corrode; must be galvanically isolated. Fasteners in carbon must be clearance fit and non-reactive.
Usual factor is 1.5 applied to loads, whether it's composite or metal, and the allowables on the material properties dictates part thickness/geometry. Composites are designed to a strain level rather than a stress level.
If margin is too high, plane won't fly because of increased weight. Some spacecraft are designed to lower factors, 1.1, to reduce weight for launch if loads after launch are minimal. Expendable rockets can use 1.25 as factor to decrease their weight. But the lower the factor, the less tolerance for operational errors.
Icon A5 uses carbon composite control rod. This is what they displayed at AirVenture.
