Plan for resolution of Tracker sidewall layup issues and EM
sidewall production:
- Meeting
to review issues with Swales, Hytec, etc. 8/14/03
- Revise
and review drawings
- Revision
to layup drawings has been done by BJ
- BJ
has prepared new assembly drawings (insert gluing); see the web drawing
tree
- Prepare
clear drawings and specifications for the complete set of coupons (who?)
- strength
(ASTM)
- thermal
conductivity
- joint
testing (insert pullout)
- Get
prepreg on order from COI (Plyform or SLAC or both?)
- Resolve
issues on how to pull the coupons without breaking at the clamps
- Use
existing left-over prepreg to make coupons of the LAT Tracker layup
(according to the above mentioned drawings) at Plyform. In all cases cut the coupons from the
interior of a layup, with large enough border wastage to ensure that the
coupons suffer no loss of resin.
- Prepare
a drawing of the layup and the coupons to be cut
- Review
the drawings and test plan
- Prepare
the coupons
- Execute
the pull tests
- Review
the results
- Procure
aluminum foil of greater than the full sidewall width
- Receiving
of new prepreg at Plyform
- Prepreg
tests (resin content and fiber weight)
- Laminate
tests on coupons cut from the interior of test layups
- Preproduction
review of all drawings, specifications, prepreg test results, fabrication
plans
- Lamination
of new panels according to approved and released drawings
- Coupon
tests
- Cut
and machine coupons according to approved and released drawings
- ASTM
strength tests
- Send
thermal coupons to SLAC or Hytec to have tested
- Assemble
joint coupons (insert installation)
- Pull
joint coupons at Hytec?
- Assemble
sidewalls
- Machining
to approved and released drawings
- Post-bonding
of aluminum foil
- Insert
bonding
- Sidewall
inspection and approval
