How Many & What Design ?
Why build staves ?
We haven’t built many recently (corrugated ?)
Need to develop stave cores designed for 130nm ASICs (small bore CP2 tube + Allcomp foam)Need to check out new toolingNeed staves for sector prototypeNeed to verify if improvements in co-curing an be translated to stavesNeed to do more prototyping to decide on final stave core (i.e. honeycomb / foam / custom corrugations) How Many4-6 ?

Suggestions
What to keep constant
Use our ‘best’ (i.e. newest) pre-
pregs K13C2U/EX-1515 at 45 and 100 gsmCo-cured face sheetsTitanium tubesKeep woven ‘C’-channels1.2m length x 12 off
End close-outs (peek)6 sets
What to vary
Fibre
gsm
Tube diameter
Stave 250 will require (at least) 1/8”130nm will most likely allow 2.275mmThermal interface foamPocofoamAllcomp foamCore material (from)3/8” CF honeycomb3/16” N636 (replacement for Korex)CorrugationsCarbon foam

Material needed for new staves
Here is the list of the materials we need for 4 Staves (from Paul
Rossiter
): Pre-preg: we have enough material to make 4 planksTapes: 8 offCooling pipe: 4 offC channels: 10 off at 1.2m long or 20 off @ 60cm longPoco foam: 1 piece 52mm x 90mm x 300mmHoneycomb: 1 piece 600mm x 900mm
Corrugated CF (if to be used): 30 off 50mm x 600mm
