The failure mode behavior and the mechanical performance in terms of stress-strain of Carbon Fiber Reinforced Plastic - Steel Plate Cold Commercial (CFRP-SPCC) hybrid thin laminates are investigated in this study through axial tensile and flexural tests. Four different adhesives were used. Materials were characterized using Differential Scanning Calorimetry (DSC) and Fourier-transform infrared spectroscopy (FTIR). Surface behavior was monitored in real time and after completion (final failure) with an optical microscope during the tensile test. The results from DSC and FTIR show that the materials undergo complete curing. The results from the tensile test indicate that by adding SPCC in hybrid laminates, the premature failure of CFRP laminates can be delayed up to 58.5%. The result shows the strain at failure increases from 1.85% of CFRP laminates to 2.1% of hybrid laminates, which equals an increased rate of more than 13%. The flexural tests demonstrate that hybrid laminates have a higher strain value compared to CFRP laminates. With the addition of SPCC layers, the failure mode is shifted from premature fiber breakage to adhesive breakage followed by final failure with fiber breakage originating from the CFRP laminates.

通过轴向拉伸和挠曲测试，研究了碳纤维增强塑料-钢板冷商业（CFRP-SPCC）混合薄层压板的失效模式行为和根据应力应变的机械性能。使用了四种不同的粘合剂。使用差示扫描量热法（DSC）和傅里叶变换红外光谱（FTIR）对材料进行表征。在拉伸试验期间，使用光学显微镜实时监测表面行为，并在完成（最终破坏）后对其进行监测。DSC和FTIR的结果表明该材料已完全固化。拉伸试验的结果表明，通过在混合层压板中添加SPCC，CFRP层压板的过早失效可以延迟至58.5％。结果显示，破坏应变从1增加。85％的CFRP层压板到2.1％的混合层压板，这意味着增长率超过13％。挠曲测试表明，与CFRP层压板相比，混合层压板具有更高的应变值。通过添加SPCC层，失效模式从纤维过早断裂转变为粘合剂断裂，随后最终断裂，而纤维断裂源自CFRP层压板。
