PC-CF is carbon-fibre-filled polycarbonate. Makers sell it for rigid functional parts and structural components needing heat resistance and dimensional stability. It is amorphous as printed, so it softens at its glass transition: its HDT at 0.45 MPa is 119–140 °C. On the H2C it prints at 275–290 °C, most products need a hardened nozzle, and some ask for bed or chamber heat beyond the H2C's limits.

Partly documented Notched Charpy impact and price rest on 1 product each, tensile modulus (XY) and HDT at 0.45 MPa on 4 products each and tensile strength (Z) is not published. Each figure is the median of the products that publish it comparably, and beside it the middle half of them; a value on a test bar no document describes as printed, or with no stated test load, is set apart, except a heat deflection of a plastic that cannot crystallise, which its glass transition sets, unless its document points to a moulded or resin bar.

Among the materials

Carbon fibre raises PC's HDT at 0.45 MPa by 5 °C: PC-CF's HDT at 0.45 MPa is 128 °C against 123 °C. Carbon fibre raises PC-ABS's HDT at 0.45 MPa by 16 °C: PC-CF's HDT at 0.45 MPa is 128 °C against 112 °C. Among the materials, PC-CF has a high tensile modulus (XY), tensile strength (XY) and price, and a low elongation at break (XY): each is in the top or bottom quarter of the materials that publish it. The rest of its key properties sit in the middle half.

PC-CF costs more than PC, PC-ABS and PET-CF and others but is less tough in notched Charpy than PC-ABS, PA12-CF and PA6-CF

How the numbers are worked out

Mechanical properties

Printed flat (XY), PC-CF typically reaches a tensile strength of 70 MPa at a modulus of 4.65 GPa, and breaks at 2.1 % elongation. In bending, its flexural strength is typically 89 MPa at a flexural modulus of 3.7 GPa.

PC-CF's products spread most in tensile modulus: the middle half runs 2.98⁠–⁠6.39 GPa

Thermal properties

PC-CF is amorphous as printed, so it softens at its glass transition, typically 127 °C: its HDT is 128 °C under 0.45 MPa and 129 °C under 1.8 MPa. As published, Vicat softening is typically 130 °C.

Printing on the H2C

PC-CF softens near 128 °C, above the H2C's 65 °C chamber; 1 product asks for more than the H2C gives

What does printing it on the H2C take, and how hot can a part get?

  • share of the products that accept each temperature
  • what most products accept
  • one end given ("at least")
  • the H2C's limit, and beyond it
  • a product
  • PC-CF: its products' median and middle half
  • as published, under each sheet's own test

What makers say about printing it

Nozzle wear

Moisture sensitivity

  • As the PCCF10 filament absorbs moisture easily due to the added carbon fiber, it should be dried before being used. Flashforge PCCF10, data sheet, p. 3
More from makers: printing advice, warping and shrinkage, adhesion between layers, supports and removal and odour and emissions

Printing advice

Warping and shrinkage

  • The carbon fibre reduces the polycarbonate’s tendency to warp during printing, whilst increasing its mechanical properties. Nanovia PC CF, data sheet, p. 1

Makers rarely give the concentration, temperature or duration: treat them as indications, not design data. Each product's statements are on its card.

Where no maker of these products speaks to an exposure, reference data for plain PC resin is shown. Fillers, pigments and printing change it, so it does not stand for these products.
