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 is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Mechanical
Is Copper C10100 stronger than FDM PAHT-CF?
FDM PAHT-CF is stronger: its tensile strength is 92 MPa against yield strength 69 MPa for Copper C10100 (33%).
Which is lighter, Copper C10100 or FDM PAHT-CF?
FDM PAHT-CF is lighter: 1,060 kg/m³ against 8,941 kg/m³ for Copper C10100.
Which is stiffer, Copper C10100 or FDM PAHT-CF?
Copper C10100 is stiffer: Young's modulus 117 GPa against 3.86 GPa for FDM PAHT-CF, so the same part in Copper C10100 deflects less under the same load.
Which is lighter for the same job, Copper C10100 or FDM PAHT-CF?
For the same stiffness or strength: Copper C10100 is lighter for a stiff rod or tie (tension); FDM PAHT-CF is lighter for a 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).
Which is more ductile, Copper C10100 or FDM PAHT-CF?
Copper C10100 stretches further before it breaks: 45% elongation at break against 8.4% for FDM PAHT-CF.
