Aiming at the preparation and forming of SS/CFRTP/SS composite components (CFRTP, thermoplastic carbon fiber composites; SS, stainless-steel), a mixed co-punching forming method of carbon fiber composites and stainless-steel is proposed. The effects of different surface treatments of stainless-steel on the shear strength, bending strength and crushing energy absorption of SS/CFRTP/SS composite components were also investigated, and the effects of ply angle on crushing energy absorption and bending strength of composites components were studied. The results show that the effect of SS/CFRTP/SS composite components prepared by mixed co-punching is very ideal. The bending strength of SS/CFRTP/SS composite component with 0 °/45 °/90 ° ply is the best, and the 0-direction ply has the best energy absorption effect. The addition of PA6 material between layers did not enhance the effect. The mechanical properties of SS/CFRTP/SS composite components with coupling agent after wire brush grinding are better than those obtained by only wire brush grinding. XPS analysis shows that the added silane coupling agent becomes a bridge to transfer stress load between the two materials through chemical reaction with the surfaces of the two materials. The micropores formed after surface treatment of stainless-steel form interlocking connection with CFRTP matrix. The excellent composite effect of SS/CFRTP/SS composite components is the result of physical and chemical interaction.

针对SS/CFRTP/SS复合材料部件（CFRTP，热塑性碳纤维复合材料；SS，不锈钢）的制备与成型，提出了一种碳纤维复合材料与不锈钢的混合共冲成型方法。还研究了不锈钢不同表面处理对SS/CFRTP/SS复合材料构件剪切强度、弯曲强度和压碎能量吸收的影响，并研究了层板角度对复合材料构件压碎能量吸收和弯曲强度的影响。学习了。结果表明，混合共冲制备的SS/CFRTP/SS复合材料组分效果非常理想。0°/45°/90°铺层的SS/CFRTP/SS复合材料构件抗弯强度最好，0向铺层吸能效果最好。在层间添加 PA6 材料并没有增强效果。丝刷研磨后SS/CFRTP/SS复合材料与偶联剂复合材料的力学性能优于仅通过丝刷研磨获得的力学性能。XPS分析表明，加入的硅烷偶联剂通过与两种材料表面的化学反应，成为传递两种材料之间应力载荷的桥梁。不锈钢表面处理后形成的微孔与CFRTP基体形成互锁连接。SS/CFRTP/SS复合材料组分优异的复合效果是物理和化学相互作用的结果。XPS分析表明，加入的硅烷偶联剂通过与两种材料表面的化学反应，成为传递两种材料之间应力载荷的桥梁。不锈钢表面处理后形成的微孔与CFRTP基体形成互锁连接。SS/CFRTP/SS复合材料组分优异的复合效果是物理和化学相互作用的结果。XPS分析表明，加入的硅烷偶联剂通过与两种材料表面的化学反应，成为传递两种材料之间应力载荷的桥梁。不锈钢表面处理后形成的微孔与CFRTP基体形成互锁连接。SS/CFRTP/SS复合材料组分优异的复合效果是物理和化学相互作用的结果。
