Aircraft Timber panel question

[Lyndon]

I'm doing a cargo area. Bolted into a chrome moly frame. 

Bunnings, a caravan builder or speciality aircraft wood.

I'm after the lightest strongest available with cost In mind.

It's not structural.

Thanks Lyndon

It depends a bit on the impact resistance required (point load). Lightest is ply or fibreglass sandwich panel if no heavy point loads, strongest & easiest is alu composite panel.

Very much depends on the configuration of the aircrafts (fuselage).

My Sonex is volume challenged (limited cargo space).

It has a fabric luggage/cargo area (up to 18kg) behind the seat with a zip lid that doubles as a shelf, accessible in the air - good for maps etc.

Accessible via two seat back hinged aluminium panels, an under/behind seat back, "pocket" (7 kg) This full fuselage width, triangular in cross section, stowage area has been created using very thin/light aviation grade plywood, as the back. Its for infrequently used items that I like to have with me on every flight eg first aid kit, tools, windscreen cleaning kit, jack, spare inner tube, etc

Not yet modified , is the under seat space - If I do this it will be using the same system as for the seat back.😈

Balsa with good thin Plywood glued each side side would be excellent.  Nev
