PA10T CF30 vs PA10T GF30

Polymer · PA10T grade comparison

PA10T CF30 and PA10T GF30 are two grades of the same polymer grade, PA10T: CF30 (30 % carbon-fiber reinforced) versus GF30 (30 % 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 190 MPa (27.6 ksi) for PA10T GF30, about 21% more. In exchange, PA10T GF30 is the more ductile: elongation 2.5% versus 1.8% for PA10T CF30. PA10T CF30 is lighter (1.28 g/cm³ vs 1.35 g/cm³ for PA10T GF30) and PA10T CF30 is stiffer (20 GPa vs 10 GPa). On the shop floor, PA10T GF30 machines more easily (fair vs poor).

PA10T CF30Choose it when strength drives the design, or when weight is the constraint.

PA10T GF30Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
