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 ABS are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is FDM PAHT-CF stronger than Plastic ABS?
FDM PAHT-CF is stronger: its tensile strength is 92 MPa against yield strength 38.1 MPa for Plastic ABS (2.41x).
Which is lighter, FDM PAHT-CF or Plastic ABS?
FDM PAHT-CF is lighter: 1,060 kg/m³ against 1,100 kg/m³ for Plastic ABS.
Which is stiffer, FDM PAHT-CF or Plastic ABS?
FDM PAHT-CF is stiffer: Young's modulus 3.86 GPa against 1.96 GPa for Plastic ABS, 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 ABS?
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 be
FDM PAHT-CF
Plastic ABS
Stiff rod or tie (tension)
lighter
2.04x heavier
Stiff beam (bending)
lighter
46% heavier
Stiff panel or plate
lighter
30% heavier
Strong rod or tie
lighter
2.51x heavier
Strong beam
lighter
1.87x heavier
Strong panel or plate
lighter
1.61x 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).
Which is more ductile, FDM PAHT-CF or Plastic ABS?
FDM PAHT-CF stretches further before it breaks: 8.4% elongation at break against 4.6% for Plastic ABS.
