Appeal No. 2002-2114
Application 09/164,792
APPENDIX
8. A method for reducing core crush during manufacture of a
chamfered composite honeycomb sandwich panel having a laminate
face sheet adhered to a honeycomb core, the core having a
chamfer, comprising the step of:
contacting a carbon or fiberglass fabric tiedown ply with
the honeycomb core of the panel in the region of the chamfer to
prevent slippage between the core and the laminate face sheet.
9. The method of claim 8 wherein the laminate face sheet
includes a barrier film to prevent resin flow from the laminate
face sheet into cells of the core.
10. A method to provide egress for escape of volatiles from
a honeycomb core during autoclave curing of a composite sandwich
panel containing the core, comprising the steps of:
positioning a carbon or fiberglass fabric tiedown ply in
contact with the core between the core and a laminate adhered
over the core, the ply allowing volatiles to escape from the core
and equalizing the pressure between the core and an autoclave
during cure of the panel.
