CCF300 vs T800H
Composite · grade comparison
CCF300 and T800H are both composite grades. T800H is the stronger of the two: tensile strength 5,490 MPa (796 ksi) against 3,530 MPa (512 ksi) for CCF300, about 56% more. T800H is the more ductile: elongation 1.9% versus 1.6% for CCF300. T800H is stiffer (294 GPa vs 230 GPa) and T800H runs hotter in service (400°C vs 350°C continuous).
T800HChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
CCF300 vs T800H: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all composite 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.

CCF300 vs T800H — frequently asked
Is T800H stronger than CCF300?
Yes. T800H has a typical tensile strength of 5,490 MPa (796 ksi) against 3,530 MPa (512 ksi) for CCF300 — about 56% more.
Which is cheaper, CCF300 or T800H?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, CCF300 or T800H?
CCF300, by a small margin. Both rate poor for machinability — 25/100 against 18/100 for T800H.
