Stave C channel side closeout gluing jig
S YangWP4 monthly meeting at Liverpool University
26th March 2014
C channel gluing jig assembly
Some design feature
CF c-channel (same as that used to build the stave) is used as a spacer.
• Face sheet thickness: 0.35mm• Glue layer: 0.1mm• CF C= channel outer dimension: H5.1mm x W4.0mm (refer to Peter’s drawing)
Interface to the stave building vacuum jigInterface to the co-cured face sheet
Main frame
C channel tolerance
If C-channel final height is 5.1+0.05, then the glue thickness could be only 0.05mm, so question: should C-channel tolerance be ??
Also if C-channel is on max tolerance, then there will be a gap between clamping piece and C channel inner face; that means there is no positive pressing on the C channel to the face sheet. Therefore, sufficient glue thickness is required to fill in the voids.
Stave building vacuum jig
Holes for C channel jig
The width of the stave can be adjusted to 110, 115 and 120mm, by moving the top and bottom clamping pieces towards or away from the centre line of the stave .
Holes for stave building tooling
For face sheet alignmentDowel holes for locating the rulers for masking and gluing.
Some questions about dimensions
50mm ?70mm?
50mm?
