... will galvanically corrode in contact with carbon fibers. Titanium alloy (Ti-6Al-4V) is usually the best fastener material for carbon fiber composites because of its high strength-to-weight ratio and corrosion resistance. When higher strength is required, cold-worked A286 iron-nickel or the iron-nickel based alloy...

...-shaped impingement ring ( Fig. 11 ) is forced into the stock to lock it tightly against the die. The ring also forces the work metal to flow toward the punch, so that the part can be extruded out of the strip without fracture or die break. Die clearance is extremely small, and punch speed is much slower...

Fabric-lined bearings can be run with smaller operating clearances than solid plastic bearings because there is less plastic (the liner) to expand with temperature and to use up running clearances. Also, these liners can be made with different thicknesses of knit materials...
