为探索一种经济有效的汽车用CFRP-钢混杂层合板共固化工艺，对CFRP-钢混杂层合板热压短时间共固化及固化条件对层间剪切强度的影响进行了试验研究。采用了一种几分钟固化的新型碳纤维预浸料。研究了不同的固化条件，包括有和没有金属层的表面处理，有和没有胶粘剂膜，三种胶粘剂膜，和三种固化压力。对混杂层合板进行短梁三点弯曲试验，以评估混杂层合板的层间剪切强度。根据实验结果，提出了一种经济有效的共固化工艺。
In this paper, short time co-cure of CFRP–steel hybrid laminates using hot pressing and the effects of curing conditions on the interlaminar shear strength (ILSS) of the hybrid laminates are investigated experimentally to explore a cost-effective co-cure process of CFRP–steel hybrid laminates for automotive applications. A new kind of CFRP prepreg which can be cured in several minutes is used. Various curing conditions including those with and without surface treatment of metal layer, those with and without an adhesive film, three kinds of adhesive films, and three curing pressures are investigated. Short beam three-point bending tests for the hybrid laminates are conducted to evaluate the ILSS of the hybrid laminates. A cost-effective co-cure process is proposed based on the experimental results.
