Title:
ピッチ繊維の高温、低酸化安定化
Document Type and Number:
Japanese Patent JP3727664
Kind Code:
B2
Abstract:
The present invention provides a process for thermosetting pitch fibers in reduced times, at low concentrations of oxygen and at higher temperatures than previously possible. Additionally, the present invention provides a pitch fiber which has an oxygen diffusion rate to the center of the fiber which is competitive with the rate of oxidation at the fiber's surface. Further, the present invention provides a high density pitch fiber batt which thermosets without loss of fiber structure.
