Wholly Aromatic Fiber Polyetheretherketone (PEEK) Fiber For
Aerospace And Composite Materials
Properties:
PEEK specialty fiber is produced by high temperature melt spinning
of PEEK resin.
1. High temperature resistance: UL temperature index 250℃.
2. High strength: Purity resin up to 94MPa, fiber enhanced up to
210MPa.
3. Chemical resistance: except sulfuric acid, almost insoluble in
any regular chemical reagents.
4. Irradiation resistant: resistant to 109 rad, equivalent nuclear
reactor radiation intensity.
5. Creep resistance: especially high temperature creep resistance,
equivalent nylon normal temperature
endurance at 150℃,
6. High flame retardancy: can meet 94V-1 of 0.3mm thick, can meet
94V-0 of 1.5mm thick,
7. Only produce H2O and CO2 when fully burned, does not produce any
toxic gas.
8. Excellent high temperature hydrolysis resistance: there is still
enough endurance at more than 200℃.
9. High tensile strength of 400 ～ 700MPa: monofilament rupture
strength about 25~40cN/tex,
multifilament up to 65 cN/tex.

Introduction and Application:
1. PEEK fiber is a wholly aromatic fiber with the presence of ether
bonds and ketone bonds, which makes the fiber's high temperature
resistance, friction and corrosion resistance much higher than
conventional fibers.
2. PEEK fiber is mainly used in aerospace, composite materials for
structural components required for weaponry, braided sheath for
aerospace high-performance wire and cable, and dry canvas for paper
making machinery in civil fields, heat-resistant filter cloth, Heat
resistant and corrosion resistant textile tape, Composite materials
(mixed with glass fiber, carbon fiber), high temperature resistant
materials for the energy industry
