This paper presents an experimental material campaign focusing on fiber-reinforced polymers (FRP) to be applied in a novel bridge deck panel. Laminas based on most commonly used fibers, i.e., glass, carbon, basalt and aramid, were prepared and studied in tension, shear and compression. In the subsequent test stages, different fabric reinforcements (uni- and bi-directional fabrics, woven fabrics, CSM layers) were considered for glass laminas only, and finally, a resultant laminate was designed and tested. Such an approach gives a great opportunity to create "tailor-made" laminates, as required in FRP bridge deck panels. Simultaneously with the laboratory tests, analytical calculations were performed using a few micromechanical models that aimed to determine engineering constants and strength parameters. Then, the results obtained from material testing and analytical calculations were compared, and conclusions on the compliance were drawn. Based on this validation, further analytical calculations may replace time-consuming laboratory tests and facilitate FRP deck design.
本文介绍了一项以纤维增强聚合物（FRP）为重点的实验材料研究活动，这些聚合物将应用于新型桥面板。制备了基于最常用纤维（即玻璃纤维、碳纤维、玄武岩纤维和芳纶纤维）的层板，并对其进行了拉伸、剪切和压缩试验研究。在随后的试验阶段，仅针对玻璃纤维层板考虑了不同的织物增强材料（单向和双向织物、机织物、连续毡片层），最后设计并测试了一种最终层板。这种方法为制造FRP桥面板所需的“定制”层板提供了绝佳机会。在进行实验室测试的同时，使用了一些微观力学模型进行分析计算，旨在确定工程常数和强度参数。然后，将材料测试和分析计算得到的结果进行比较，并得出关于符合性的结论。基于这种验证，进一步的分析计算可以取代耗时的实验室测试，并促进FRP桥面板的设计。
