Hi Marting,
130 Watt sounds good, excellent in fact.
15mm wood would cut OK but bear in mind the effective focal distance of the beam and associated kerf width. You would also need a lot of air assist.
As for polycarbonate, well you would just have to try it and see – it is terrible stuff and can often end up as a sticky lump. Acrylic would be best.
I doubt you would have enough power to cut into aluminium at the CO2 wavelength but you can certainly ablate the anodizing dye layer.
Sound like you are in for a lot of fun. Please keep us informed and post some pictures of your progress.
Tweakie.
