Why it exists

TECAPEEK CF30 black is a 30 % carbon-fibre-filled PEEK compound. The current Ensinger page prints a density of 1.38 g/cm3, a tensile modulus of 6000 MPa and a melting temperature of 341 °C. The 2015 datasheet prints a density of 1.41 g/cm3, so the two sources disagree and both are kept.

Where it's used

Aerospace structures

Ensinger lists aircraft and aerospace technology among the target industries for TECAPEEK CF30 black. The 2015 datasheet gives very high stiffness and very high creep resistance as main features.

Sliding and wear parts

Ensinger states that carbon fibre composites are less abrasive than glass fibres and give improved wear and friction properties.

Recipe

(C19H12O3)n

TECAPEEK CF30 black is a polyetheretherketone (PEEK) matrix filled with 30 % carbon fibre. PEEK has the formula (C19H12O3)n per Wikipedia and is made by reaction of 4,4'-difluorobenzophenone with the disodium salt of hydroquinone. The carbon fibre filament is produced from a precursor such as polyacrylonitrile (PAN), rayon or petroleum pitch.

PEEK matrix The remainder of the compound; the page does not print the matrix share Thermoplastic matrix, repeat unit (C19H12O3)n per Wikipedia; it carries the load between the fibres.
Carbon fibre 30 % carbon fibres as printed on the Ensinger page Stiffness and creep resistance come from the carbon reinforcement, as Ensinger states.

How it compares

Read the two datasheets together. The current Ensinger page prints a density of 1.38 g/cm3 for TECAPEEK CF30 black, and the 2015 Polymershapes datasheet prints 1.41 g/cm3 for the same grade. The 2015 datasheet gives strengths in psi, for example 17,500 psi tensile strength at yield under ASTM D638. That is a different unit and test method from the ISO 527-2 tensile strength of 112 MPa on the current page. No other profile is compared here, because no second source for a competing grade was read in this run.

The same measurements for each material, so you can compare them. Each row names the key condition under the value; the full conditions and methods are in the numbered notes under Technical details.

Why choose it, and why not

Good for

  • High stiffness and creep resistance: a tensile modulus of 6000 MPa and the creep resistance Ensinger cites.
  • Parts that need a long-term service temperature of 260 °C.

Watch out for

  • Ageing: Ensinger prints a dash for resistance to weathering, so outdoor exposure is not rated.
  • Values differ by source: 1.38 g/cm3 on the current page and 1.41 g/cm3 on the 2015 datasheet.
  • No space exposure, outgassing or atomic-oxygen data for this grade were found. NASA TM 2008-215490 lists PEEK with no carbon-fibre filler and was not used.

TECAPEEK CF30 black is a stiff, creep-resistant carbon-fibre PEEK with a density of 1.38 g/cm3 and a tensile modulus of 6000 MPa per Ensinger. The sourced values are datasheet values. No space or outgassing data for this grade were found in this run. Ensinger's handling sheet states that the compound is not classified.

Risks and side effects

Hazards to people, what happens when a cell overheats, and how the material is handled and stored.

For people

The product page confirms RoHS compliance, and Ensinger's handling sheet states that the compound is not classified. No supplier safety data sheet for this grade was read.

Compliance
Ensinger states that TECAPEEK CF30 black meets the limitations imposed by RoHS Directive 2011/65/EU for electrical equipment.
Hazard data
Wikipedia makes no explicit hazard statement for PEEK. Ensinger's handling sheet says the compound is not classified and needs no labelling. Dust and thermal-decomposition statements from a carbon rod SDS and a Victrex CT200 SDS apply to other products, not this grade.

If it fails

Only datasheet values are recorded. No failure test is recorded for this grade.

Heat
Ensinger gives a service temperature of 300 °C for short term use and 260 °C for long term use.

Handling and storage

  • The Ensinger product page links a Product Handling Information Sheet for TECAPEEK CF, which was read in this run. Its handling rules are recorded in the hazard rows above.
  • Skin contact with carbon fibres: the Ensinger sheet says to wash the skin thoroughly with cold water, not warm water, and not to rub or scratch it. For a foreign body in the eye, the sheet says not to rub the eye and to consult an eye specialist.
  • Fire: the Ensinger sheet says the product ignites in a flame but stops burning when the source is removed, that carbon dioxide and carbon monoxide are the main toxic gases, and that water spray, alcohol-resistant foam, carbon dioxide or dry chemical foam are suitable extinguishing media, while a water jet is unsuitable.
