| 摘 要： | 研究了碳布增强新型耐烧蚀树脂聚芳基乙炔（PAA）材料的烧蚀性能和力学性能，并与钡酚醛和硼酚醛进行比较。结果表明，PAA树脂的残碳率高于钡酚醛和硼酚醛树脂，C/PAA材料烧蚀性能优异，氧一乙炔线烧蚀率为0.012mm/s、质量烧蚀率为0.0166g/s，但其力学性能较差。

| Abstract: | Mechanical and ablative properties of carbon fiber cloth reinforced new ablation resistant polyary-lacetylene (PAA) are studied. Boron-phenolic composite and barium-phenolic composite are also investigated for compar-ison . Experimental results show that char yield of PAA resin is higher than that of phenolic resins. Ablative performance of the C/PAA composites is very good, with linear ablation rate of 0.012 mm/s and mass ablation rate of 0.0166 g/s un-der oxyacetylene ablation test, but its mechanical properties are relatively poor. |
