STUDY ON THE PROPERTIES OF PAN CARBON FIBRE PRECTURSOR SPINNING SOLUTION

The technological conditions of producing Polyacrylonitrile spinning solution whose molecular weight is between 50,000 and 80,000 are investigated. The properties of spinning solution, specially, the parameter of spinnability viscosity and its effect conditions are discussed. All these provide proper experimental data and scientific methods for producing high performance PAN based carbon fiber.
