Every value links to the document that states it. "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 PLA are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is FDM PAHT-CF stronger than Plastic PLA?
FDM PAHT-CF is stronger: its tensile strength is 92 MPa against yield strength 52.5 MPa for Plastic PLA (1.75x).
Which is lighter, FDM PAHT-CF or Plastic PLA?
FDM PAHT-CF is lighter: 1,060 kg/m³ against 1,240 kg/m³ for Plastic PLA.
Which is stiffer, FDM PAHT-CF or Plastic PLA?
FDM PAHT-CF is stiffer: Young's modulus 3.86 GPa against 3.25 GPa for Plastic PLA, 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 PLA?
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.

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).
