Abstract

Materially bonded hybrid systems with precisely adjusted interfacial properties are of great scientific and industrial interest with regard to lightweight construction. In the present study, a material composite of carbon fiber reinforced plastic (CFRP) and galvanized steel is considered, where the metallic surface is laser structured in order to improve the adhesion properties. The resulting joining properties will be elicited by tensile shear tests in comparison to an alkaline cleaned surface condition and blind riveting. The potential of direct-joined hybrid systems with laser-structured substrate surfaces will also be considered using an automotive roof frame as an example. In the tensile shear test, the direct-joined hybrid joint with laser-structured metal substrate achieves significantly higher joint strengths than after alkaline cleaning. Compared to an aluminum/steel reference structure, the CFRP/steel roof frame exhibits a significant weight advantage with superior mechanical properties under flexural and compressive loading.

用于汽车应用的碳纤维增强环氧树脂和镀锌钢与激光结构界面的共结合

具有精确调节的界面性质的材料结合混合系统在轻质结构方面具有巨大的科学和工业意义。在本研究中，考虑了一种由碳纤维增强塑料（CFRP）和镀锌钢组成的材料复合材料，其中金属表面被激光结构化，以提高粘合性能。与碱性清洁表面条件和盲铆接相比，拉伸剪切试验将得出最终的连接性能。以汽车车顶框架为例，还将考虑具有激光结构化基底表面的直接连接混合系统的潜力。在拉伸剪切试验中，与碱性清洗后相比，具有激光结构金属基底的直接连接混合接头实现了显著更高的接头强度。与铝/钢参考结构相比，CFRP/钢屋顶框架在弯曲和压缩载荷下表现出显著的重量优势和优异的机械性能。
