Sandwich panels are used in buildings because of their light weight, thermal insulation, sound absorption, and better mechanical properties. Material scientists have been trying their best to replace synthetic materials as these are non-biodegradable. Stringent environmental policies, need for eco-friendly products, and problems in end-of-life disposal have made natural materials in sandwich panels the need of the hour. This research work attempts to replace the synthetic sandwich panels with natural sandwich panels without sacrificing the performance. The natural sandwich panels used in this work had agglomerated cork as the core and flax fiber as skin reinforcement. A vacuum-bagging technique was used to manufacture these panels with three core densities and three skin reinforcements. The performance of these panels was confirmed by conducting flatwise tensile, flatwise compressive, and edgewise compressive tests as per the American Society for Testing and Materials standards and the results are discussed in this article. The specific flatwise tensile strength of natural sandwich panels was 14–21% higher and the specific flatwise compressive strength was 2–10% higher than the synthetic sandwich panels. The edgewise compressive strength was found to be 32–34% lower than synthetic sandwich panels. The results suggest that natural sandwich panel could be a better alternative material for building applications.

夹芯板因其重量轻、隔热、吸音和更好的机械性能而被用于建筑。材料科学家一直在尽最大努力取代合成材料，因为这些材料是不可生物降解的。严格的环境政策、对环保产品的需求以及报废处理的问题使得夹芯板中的天然材料成为当下的需要。这项研究工作试图在不牺牲性能的情况下用天然夹芯板代替合成夹芯板。这项工作中使用的天然夹芯板以软木作为核心，亚麻纤维作为表皮增强材料。真空袋技术用于制造具有三种芯密度和三种表皮增强材料的面板。这些面板的性能通过按照美国测试和材料协会标准进行的平面拉伸、平面压缩和边缘压缩测试得到证实，结果在本文中进行了讨论。天然夹芯板的比平面拉伸强度比合成夹芯板高 14-21%，比平面压缩强度高 2-10%。发现边缘压缩强度比合成夹芯板低 32-34%。结果表明，天然夹芯板可能是建筑应用的更好替代材料。天然夹芯板的比平面拉伸强度比合成夹芯板高 14-21%，比平面压缩强度高 2-10%。发现边缘压缩强度比合成夹芯板低 32-34%。结果表明，天然夹芯板可能是建筑应用的更好替代材料。天然夹芯板的比平面拉伸强度比合成夹芯板高 14-21%，比平面压缩强度高 2-10%。发现边缘压缩强度比合成夹芯板低 32-34%。结果表明，天然夹芯板可能是建筑应用的更好替代材料。
