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 TPU are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is FDM PAHT-CF stronger than Plastic TPU?
FDM PAHT-CF is stronger: its tensile strength is 92 MPa against 23.7 MPa for Plastic TPU (3.88x).
Which is lighter, FDM PAHT-CF or Plastic TPU?
FDM PAHT-CF is lighter: 1,060 kg/m³ against 1,220 kg/m³ for Plastic TPU.
Which is stiffer, FDM PAHT-CF or Plastic TPU?
FDM PAHT-CF is stiffer: Young's modulus 3.86 GPa against 0.067 GPa for Plastic TPU, 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 TPU?
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 TPU |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 66.3x heavier |
| Stiff beam (bending) | lighter | 8.74x heavier |
| Stiff panel or plate | lighter | 4.45x heavier |
| Strong rod or tie | lighter | 4.47x heavier |
| Strong beam | lighter | 2.84x heavier |
| Strong panel or plate | lighter | 2.27x 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).
