“-4”是前苏联研制的一种以薄碳带和环氧基体为基的复合材料,可用于制造在150℃以下工作的中等承力零件。此种材料按预浸料工艺进行加工制造。-411预浸料在生产场地(温度15～25℃)存放的生存能力为12个月。 预浸料可调的粘性可保证复杂结构大型零件铺层的 “-4” is a thin carbon ribbon and epoxy matrix-based composite material developed by the former Soviet Union that can be used to make medium load-bearing parts that work below 150 ° C. This material by prepreg process for manufacturing. -411 The prepreg storage capacity at the production site (temperature 15 ~ 25 ℃) for 12 months. Adjustable viscosity prepreg can guarantee the complex structure of large parts ply
