HM50E High-strength and High-modulus Polyacrylonitrile-based Carbon Fiber

Reasons for recommendation

The carbon fiber with both high strength and high modulus plays an

important role in key strategic areas such as aerospace and military

equipment, providing solutions for further lightweight and high- performance applications.

Preparative technique

The carbon precursor fiber is made from the polyacrylonitrile through the dry-jet wet spinning technology, and then experienced the process of pre-oxidation, low-temperature carbonization, high-temperature carbonization,graphitization, surface treatment, and sizing procedures to prepare the HM50E high-strength and high-modulus polyacrylonitrile-based carbon fiber.

Features of fibers and finished products

Main Specifications

Filament: 12K

Relative Standards

PAN-based carbon fiber (GB/T26752-2020)

Properties of fibers and features of finished products

. High modulus, 30% higher modulus than T800 grade carbon fiber.

. Its strength is basically the same as T800 grade carbon fiber, with excellent strength that is more conducive to light weight.

. At -180°C, it can continue to function steadily, and at 1000°C, it can continue to function almost unmodified in an inert atmosphere.

. good corrosion resistance, good resistance to most acids, alkalis and organic solvents.

The downstream application guidance

Weaving: It can be used for warp knitting fabrics, and can also be used for prepreg and winding parts.

After-finishin: Attention should be paid to the degree of fiber spreading, resin suitability and resin infiltration during the manufacturing process.

Application of fibers

Industrial textiles:Aerospace/Engine shell/UAV

Q: As research and development continues to be iterative and updated,

what are the synchronous improvements of HM50E high-strength and

high-modulus polyacrylonitrile-based carbon fiber?

A: HM50E high-strength and high-modulus polyacrylonitrile-based carbon fiber has a modulus increase of nearly 30% compared to similar high-strength carbon fibers. In addition to meeting the demands of the new generation of major composite materials for better balanced performance of carbon fiber materials, HM50E carbon fiber can simultaneously achieve high tensile strength and high modulus of elasticity. It is also the perfect material to support the third

generation of advanced composite materials, which has a wide range of potential applications in the future market.
