摘　　要：研究了纳米炭粉对炭布/苯并噁嗪复合材料层间性能和烧蚀性能的影响。结果表明,当纳米炭粉含量为5%时,炭布/苯并噁嗪复合材料的层间剪切强度提高26%达到30.3MPa,氧-乙炔线烧蚀率降低23%为0.0154mm/s。700℃高温处理后,改性后的复合材料有着较高的强度保留率。Interlaminar property and ablative property of coal eloth/polybenzoxazine composite modified with nano-carbon powder were studied in this paper. The results show that, when the nano-carbon powder＇s content is 10% ,the coal cloth/ polybenzoxazine composite＇s shearing strength enhances 26% to achieve 30.3MPa, the linear ablation rate reduces 24% is 0. 0154mm/s;after high-temperature at 700℃, modified composites have the high intensity retention rate.
