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.

Abstract translation: 本发明提供了一种在低浓度氧气和比以前可能的更高温度下减少时间的热固性沥青纤维的方法。 此外，本发明提供了一种沥青纤维，其具有与纤维中心的氧扩散速率，其与纤维表面的氧化速度相竞争。 此外，本发明提供一种高密度沥青纤维毡，其在不损失纤维结构的情况下热固性。
