Hemp based composites have been preferred in insulation applications in the last decade, especially thanks to it is superior thermophysical properties. These composites consist of natural material and are widely bonded with lime plaster. Therefore, it is accepted as an environmentally friendly material. In this study, various composites containing different types and sizes of hemp hurd particles were produced and the relation of the thermal conductivity and electrical resistivity to the unit weight of these composites was experimentally investigated. In addition to the experimental measurements on the produced composites, particle morphology of the hemp hurds was examined by SEM images. One of the main objectives of this research is to develop a new method in the evaluation of hemp based composites by investigating the relationships between the tests. For this purpose, Wenner probe method was applied for the first time in hemp based composites. Results revealed that the electrical resistivity measurements can be used to estimate the thermal performance of hemp based composites as soon as they produced. Unit weights varied between 350 kg·m⁻³ and 700 kg·m⁻³ while thermal conductivity coefficients were obtained in a range from 0.09 W·(m·K)⁻¹ to 0.18 W·(m·K)⁻¹.

在过去的十年中，大麻基复合材料在绝缘应用中受到了人们的青睐，特别是由于它具有出色的热物理性能。这些复合材料由天然材料组成，并广泛地与石灰石膏粘合。因此，它被认为是环保材料。在这项研究中，生产了包含不同类型和尺寸的麻颗粒的各种复合材料，并通过实验研究了这些复合材料的导热率和电阻率与单位重量的关系。除了对生产的复合材料进行实验测量外，还通过SEM图像检查了大麻草的颗粒形态。这项研究的主要目的之一是通过研究试验之间的关系，开发一种评估大麻基复合材料的新方法。为此，在基于大麻的复合材料中首次应用了Wenner探针法。结果表明，电阻率测量结果可用于在生产大麻基复合材料后立即估算其热性能。单位重量在350 kg·m之间变化^-3和700 kg·m ^-3，而导热系数在0.09 W·（m·K）^-1至0.18 W·（m·K）^{-1的范围内}。
