原材料

碳纤维是一种现代化的高性能材料,应用于组件需要既坚固又轻质的各种领域,如:航空航天、汽车工业、风能技术及现代体育设备。

性能

  • 非常牢固且坚硬
  • 轻质
  • 导电性
  • 多样化的加工方案

加工工艺

碳纤维是以聚合物纤维聚丙烯腈 (PAN基原丝) 为原料采用氧化和碳化工艺制作而成。根据特定的应用,碳纤维可以进一步被直接加工成纤维束、织物或非织物,或预浸树脂的半成品 (预浸料)。

原材料

由无定形、粗颗粒碳制成的模具应用于生产铝、硅金属、粗铁、硅铁和磷等的热电解工艺中。

性能

  • 耐高温
  • 导电
  • 导热
  • 耐磨损

加工工艺

无烟煤和其它添加剂与煤焦油沥青相结合可形成一种均质体,这种均质体可被压制成各种形状,并经过碳化的热处理过程。

The base material for the manufacture of expanded graphite is natural graphite. This is converted into a graphite intercalation compound. By thermal decomposition of the intercalation compounds, expanded, high-bulking graphite flakes occur which are calendered into flexible graphite foils or are compressed into sheets.
