摘要
对比了国内外针刺炭纤维预制体的发展与应用。法国Snecma公司采用针刺技术成型的预制体有Novoltex和Naxeco两种,应用于火箭发动机延伸锥、喉衬等。国产薄壁针刺C/C复合材料性能与法国针刺扩张段材料性能相当。国产针刺预制体有整体毡和炭布/网胎针刺预制体,炭布/网胎叠层针刺预制体由于x-y向引入了连续纤维,制品整体性能较好。针刺技术是炭纤维预制体的自动化成型技术,拓宽了C/C复合材料应用领域。
In the paper,the domestic and foreign development and application of needling carbon fiber perform have been compared.The Snecma in France has two kinds of needling perform：Novoltex and Naxeco,which have been used in the extendible cone,throat of（Solid Rocket Motor） SRM and so on.The properties of domestic needling C /C composites correspond to those of the needling C /C composites from France.The domestic needling perform has the whole felt and carbon cloth /felt perform.Due to the continuous filament in x-y direction,the property of carbon cloth /felt needling perform is excellent.The needling technology is an automation method to make carbon perform,which will broaden the application field of C /C composites.
