PA10T CF30 vs PA10T GF15
Polymer · PA10T grade comparison
PA10T CF30 and PA10T GF15 are two grades of the same polymer grade, PA10T: CF30 (30 % carbon-fiber reinforced) versus GF15 (15 % glass-fiber reinforced). The chemistry is identical, so every difference below comes from the condition. PA10T CF30 is the stronger of the two: tensile strength 230 MPa (33.4 ksi) against 140 MPa (20.3 ksi) for PA10T GF15, about 64% more. In exchange, PA10T GF15 is the more ductile: elongation 4.5% versus 1.8% for PA10T CF30. PA10T GF15 is lighter (1.22 g/cm³ vs 1.28 g/cm³ for PA10T CF30) and PA10T CF30 is stiffer (20 GPa vs 5.5 GPa). On the shop floor, PA10T GF15 machines more easily (fair vs poor).
PA10T CF30Choose it when strength drives the design.
PA10T GF15Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
PA10T CF30 vs PA10T GF15: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all polymer grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
