根据竹材和木材的组成结构,分析了木材和竹材自身及复合后材料的横向导热系数。研究发现,木材和竹材的导热系数与材料内部结构关系密切,自身结构的孔隙率越大,导热系数越小。针对不同的竹木复合材在厚度方向上的热传导性能不同,通过测量其导热系数、导温系数及比热,并与其它木材的导热性能相比较,分析了竹木复合材的导热性能以及结构对其导热性能的影响。试验发现,木质材料的导热性能与树种、内部结构、含水率等因素有直接关系。 According to the composition of bamboo and wood, the transverse thermal conductivity of wood and bamboo and the composite material were analyzed. The study found that the thermal conductivity of wood and bamboo are closely related to the internal structure of the material, the greater the porosity of its own structure, the smaller the thermal conductivity. According to different thermal conductivity of different bamboo composite materials in the thickness direction, the thermal conductivity, thermal conductivity coefficient and specific heat were measured and compared with other wood thermal conductivity, the thermal conductivity and structure Effect on its thermal conductivity. The test found that the thermal conductivity of wood materials and tree species, internal structure, moisture content and other factors are directly related.
