摘　　要：利用聚对苯撑苯并双恶唑(PBO)纤维与酚醛树脂制备先进复合材料,研究该单向复合材料的层间剪切性能、弯曲性能、冲击性能和动态力学性能,并分析该复合材料的吸湿脱湿行为和热氧老化行为。酚醛树脂/PBO纤维单向复合材料的层间剪切强度为21.25 MPa,弯曲强度为439.53 MPa,弯曲弹性模量为50.11 GPa。The advanced composites were prepared by using PBO fiber and phenolic resins. The interlayer shearing strength, flex strength, impact property and dynamic mechanical property of unidirectional PBO fiber/phenolic composites were investigated. The interlayer shearing strength of phenolic/PBO unidirectional composites was 21.25 MPa. The flex strength and modulus reached 439.53 MPa and 50.11 GPa.
