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 Nylon are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is FDM PAHT-CF stronger than Plastic Nylon?
FDM PAHT-CF is stronger: its tensile strength is 92 MPa against yield strength 63.1 MPa for Plastic Nylon (46%).
Which is lighter, FDM PAHT-CF or Plastic Nylon?
FDM PAHT-CF is lighter: 1,060 kg/m³ against 1,140 kg/m³ for Plastic Nylon.
Which is stiffer, FDM PAHT-CF or Plastic Nylon?
FDM PAHT-CF is stiffer: Young's modulus 3.86 GPa against 2.33 GPa for Plastic Nylon, 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 Nylon?
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 Nylon |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 1.78x heavier |
| Stiff beam (bending) | lighter | 38% heavier |
| Stiff panel or plate | lighter | 27% heavier |
| Strong rod or tie | lighter | 1.57x heavier |
| Strong beam | lighter | 38% heavier |
| Strong panel or plate | lighter | 30% 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).
