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 is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is FDM PAHT-CF stronger than Titanium?
Titanium is stronger: its yield strength is 885 MPa against tensile strength 92 MPa for FDM PAHT-CF (9.62x).
Which is lighter, FDM PAHT-CF or Titanium?
FDM PAHT-CF is lighter: 1,060 kg/m³ against 4,430 kg/m³ for Titanium.
Which is stiffer, FDM PAHT-CF or Titanium?
Titanium is stiffer: Young's modulus 115 GPa against 3.86 GPa for FDM PAHT-CF, so the same part in Titanium deflects less under the same load.
Which is lighter for the same job, FDM PAHT-CF or Titanium?
For the same stiffness or strength: FDM PAHT-CF is lighter for a stiff panel or plate, strong panel or plate; Titanium is lighter for a stiff rod or tie (tension), stiff beam (bending), strong rod or tie, strong beam.
| Part that must be | FDM PAHT-CF | Titanium |
|---|---|---|
| Stiff rod or tie (tension) | 7.1x heavier | lighter |
| Stiff beam (bending) | 30% heavier | lighter |
| Stiff panel or plate | lighter | 35% heavier |
| Strong rod or tie | 2.3x heavier | lighter |
| Strong beam | 8% heavier | lighter |
| Strong panel or plate | lighter | 35% 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).
