摘要
介绍了聚对苯撑苯并双噁唑(PBO)纤维的结构特点、性能及应用。PBO纤维分子沿轴向高度取向,其强度和初始模量高,具有耐热、阻燃、耐冲击、耐弯曲疲劳和耐化学稳定性等优良性能。PBO纤维在耐热材料、增强材料、防弹抗冲击材料以及航空领域与军事领域广泛应用。
The structure characteristics, properties and application of poly （ p -phenylene benzobisoxazole） （PBO） fiber were introduced. The molecular of PBO fiber was highly oriented axially. PBO fiber exhibited high strength and modulus and other splendid properties, such as heat resistance, flame retardance, impact resistance, resistance to flexural fatigue, chemical environmental resistance. PBO fiber can be widely used as heat resistant materials, reinforcement materials, bulletproof and impactresisting materials in aeronautic and military field.
