Each number points to the document that states it, with the exact basis. Values without a number are computed from the sourced ones. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.

FDM PAHT-CF and Plastic PETG are 3D printed: their properties depend on build direction and print settings; these are typical values.

Questions

Mechanical

Is FDM PAHT-CF stronger than Plastic PETG?

FDM PAHT-CF is stronger: its tensile strength is 92 MPa against yield strength 46.2 MPa for Plastic PETG (1.99x).

Which is lighter, FDM PAHT-CF or Plastic PETG?

FDM PAHT-CF is lighter: 1,060 kg/m³ against 1,270 kg/m³ for Plastic PETG.

Which is stiffer, FDM PAHT-CF or Plastic PETG?

FDM PAHT-CF is stiffer: Young's modulus 3.86 GPa against 1.94 GPa for Plastic PETG, so the same part in FDM PAHT-CF deflects less under the same load.

Which is lighter for the same job, FDM PAHT-CF or Plastic PETG?

For the same stiffness or strength: FDM PAHT-CF is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.

Part that must beFDM PAHT-CFPlastic PETG
Stiff rod or tie (tension)lighter2.39x heavier
Stiff beam (bending)lighter1.69x heavier
Stiff panel or platelighter1.51x heavier
Strong rod or tielighter2.39x heavier
Strong beamlighter1.9x heavier
Strong panel or platelighter1.69x heavier

For the same stiffness or strength, mass scales with density over stiffness (or strength) raised to a power set by how the part is loaded: 1 for a rod in tension, 1/2 for a beam in bending, 1/3 for a panel (the standard material-selection indices).
