Other CCF700 grades and fills

CCF700 is listed in 7 conditions; see the grade overview at CCF700.

Compare all 7 grades and fillsHide
Grade · open for datasheetBest forYield MPaTensile MPaElong. %Hardness
Plain/twill woven fabric epoxy laminate, Vf ≈ 55% (warp)
Pick the 3K/12K woven prepreg laminate for shells, panels and visible parts where balanced biaxial properties and drape over curvature matter more than peak 0° stiffness.—8501.4—
Unidirectional BMI / high-Tg matrix laminate
Choose the BMI matrix when the laminate must serve continuously at 180–230 °C, as in engine nacelles and high-speed vehicle skins; Tg 280 °C comes with a higher cure temperature.—2,3001.6—
Unidirectional epoxy laminate, Vf ≈ 60%
Most common laminate form: use the Vf ≈ 60% unidirectional layup for aircraft and UAV primary structure and design to the quoted 0° properties, since transverse strength is resin-limited.—2,4501.7—

24K dry tow

Chemical Resistance SummaryCarbon fiber itself is inert to most acids, alkalis and solvents except hot oxidizing acids; laminate performance is matrix-controlled. Direct contact with aluminium or steel causes galvanic corrosion of the metal.

Working with CCF700 FW-VESSEL

Is CCF700 easy to machine?

Machine only with diamond-coated or PCD tooling at high speed and small feed. Use backing plates to prevent delamination and extract dust under negative pressure, since conductive dust can short electrical equipment.

Can CCF700 be welded?

Not weldable; join by structural epoxy adhesive bonding or mechanical fasteners. Use titanium or stainless fasteners with insulating washers to avoid galvanic corrosion.

Can CCF700 be formed, bent or molded?

Dry fiber is wound, braided or fiber-placed; prepreg is cured in an autoclave at 0.3–0.6 MPa and 120–180 °C, or press moulded, RTM or vacuum infused. Fix fiber orientation and fiber volume fraction by ply sequence before cure.

What surface finishes work on CCF700?

Sand the surface and apply primer or clear coat for UV protection. A surface veil or adhesive film improves appearance, and any exposed fiber should be sealed with additional resin.

Is CCF700 FW-VESSEL easy to machine?

Not especially — machinability is rated poor (25/100, worse than 65% of composite grades). Machine only with diamond-coated or PCD tooling at high speed and small feed. Use backing plates to prevent delamination and extract dust under negative pressure, since conductive dust can short electrical equipment.

Can CCF700 FW-VESSEL be welded?
