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 Plastic Polycarbonate?
FDM PAHT-CF is stronger: its tensile strength is 92 MPa against yield strength 65 MPa for Plastic Polycarbonate (42%).
Which is lighter, FDM PAHT-CF or Plastic Polycarbonate?
FDM PAHT-CF is lighter: 1,060 kg/m³ against 1,200 kg/m³ for Plastic Polycarbonate.
Which is stiffer, FDM PAHT-CF or Plastic Polycarbonate?
FDM PAHT-CF is stiffer: Young's modulus 3.86 GPa against 2.4 GPa for Plastic Polycarbonate, 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 Polycarbonate?
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 Polycarbonate |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 1.82x heavier |
| Stiff beam (bending) | lighter | 44% heavier |
| Stiff panel or plate | lighter | 33% heavier |
| Strong rod or tie | lighter | 1.6x heavier |
| Strong beam | lighter | 43% heavier |
| 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).
