35K Polyacrylonitrile carbon fiber

Extreme collision and iterative upgrade. Delicate and tough fiber bears the exploration and innovation of fiber practitioners.Benefited from the cross of fiber boundary,breakthrough of limit, perfect fusion with the extreme, and the collisions to gain endless possibilities and

amazing charm, each strand shows exquisite skills and ingenuity to realizie hard core protection. Fiber hasbecome more and more lighter, stronger, tougher and resistant to high temperature,

facilitating its use in anti-cutting clothing, shoematerials, fire-fightingclothing, flight clothing,military equipment, urban light box cloth, fluedust removal, wind power blades, aerospace and

other fields. Fiber shows its best accompanying in extreme details and high value in extreme environments.

FIBER EXTREME UPGRADE

INDUSTRIALFIBER

Industrial fiber, creating a new model with hardcore strength. Fluorine-free anti-wicking polyester industrial yarn effectively solves the problems of product appearance deterioration and mould, caused by siphonic effect, awakening the colorfulness of cities.35K polyacrylonitrile and high fatigue resistance.With the outstanding advantages of low manufacturing cost and light weight, it facilitates the upgrading of wind turbine blades and aerospace products.

35K Polyacrylonitrile carbon fiber

Recommendation Reasons

35K carbon fiber has high strength, high modulus, and high fatigue

resistance. With the advantages of low manufacturing cost and light

weight, it facilitates the upgrading of wind blades and aerospace products.

Processing Technology

Acrylonitrile is used for continuous polymerization, and then DMAc is used as polymer dissolving solvent. The two-step wet spinning method is used to produce 35K polyacrylonitrile precursor fiber. Afterwards, such processes as pre-oxidation pretreatment, low-temperature-high-

temperature carbonization, and deep homogeneous surface treatment are performed to produce 35K polyacrylonitrile carbon fiber.
