Subject: OMC #002 Delamination repair Part1 (2) 

EP30-2 preparation

  • Two Al foil cups + A sheet of Al foil (for test cure)
  • Set a tube on the glue gun
  • Attach an applicator tube
  • Push a couple of times, and dispense the glue for a single stroke on a waste Al cup
  • Pour the 6g of glue to the other cup.
  • Add 0.3g of silica beads powder to the cup
  • Steer. Pick a few drops to the test cure Al foil
  • Bake the test piece for 15min in 200F (95degC) ==> Very good

#1 The Invar bar on the cable bracket (DCPD side)

Added short (frosted) Al bars (Attachment 1) to the short sides of the invar bar. (Attachments 2/3). Some glue was sucked into the delamination gap by capillary action (=good) (Attachment 4)

#2 The Invar bar on the cable bracket (QPD side)

Added short (frosted) Al bars to the short sides of the invar bar. (Attachments 3/5). Maybe some glue was sucked into the delamination gap??? Not so clear. (Attachment 4)

#3 The Invar bar reinforced in 2016

Added a short (frosted) Al bars to a short side of the invar bar (Attachment 6). On both sides of the 2016 reinforcement, rectangular prisms are added (Attachment 6)
Some capillary action is visible beneath the invar bar (Attachment 7)


Leave it as it is for a day
