during disassembly due to the soft nature of the tool 48 and the lack of resin stuck to the leads 13 furthermore most epoxy resins will not bond to rtv particularly when it has been treated with a release agent most fiber optic sensor leads 13 are broken during de bagging operations mold disassembly this soft rubber tool 48 entirely envelops the lead 13 and the first item removed during the breakout are the rubber plugs 56 around the strain relief 58 primary area of failure there is little chance of damaging the lead 13 during disassembly due to the soft nature of the tool 48 and the lack of resin stuck to the leads furthermore most epoxy resins will not bond to rtv particularly when it has been treated with a release agent the final step in the installation of the fiber optic leads 13 is the fabrication of a strain relief boot 42 to protect the lead egress point and to armor the fiber optic lead 13 the boot 42 as shown in fig6 a 6 c is cast with a two part aerospace epoxy such as ea 9394 made by dexter hysol the dimensions are roughly 1 0 inches by 0 5 inches.
