一种纳米纤维增韧碳纤维树脂基复合材料的制备方法,属于复合材料领域。其特征为采用热塑性工程塑料的纳米纤维毡或膜作为增韧部分。其制备方法是:将碳纤维的预成型体作为静电纺丝的负极接收器,直接将热塑性工程塑料纳米纤维毡或膜纺丝于预成型体上,所纺纳米纤维毡或膜相对于碳纤维预成型体的树脂基体具有质量比例;将含有纳米纤维毡或膜的碳纤维的预成型体铺层,制备含纳米纤维夹芯结构的碳纤维预成型
A nanofiber-toughened carbon fiber resin-based composite material preparation method belongs to the field of composite materials. It is characterized by the use of a thermoplastic engineering plastic nanofiber mat or film as the toughening part. The preparation method comprises the following steps: using a carbon fiber preform as a negative electrode electrospinning receiver, directly spinning a thermoplastic engineering plastic nanofiber mat or film onto a preform, and spinning the nanofiber mat or film relative to the carbon fiber preform The resin matrix of the body is in a mass ratio; preforming a preform of a carbon fiber containing a nanofiber mat or a film to prepare a carbon fiber containing a nanofiber sandwich structure
