Encapsulation/bonding Ti-6Al-4V internal chainplates

Thanks for the post reply. Google "china doll Chainplate project" to see pics of the plates encapsulated. The epoxy with 403 high density was used with bi-axial cloth in three laminates. Note that the titanium plate did not need passivation and was sandblasted in finish. This greatly improved adhesion to the metal and the hull polyester was activated with acetone after being grit sanded. When pulling the old plate off the hull, the chromium oxide left a blue hue and the plates were easily pried from the hull, with some pressure and a good "pop." A test to attempt to remove a newly epoxied on plate was unsucessful at significantly greater pressures.
