The subject of the research is wood polymer-sand composite (WPSC) and study of its physical and mechanical properties. In this case it is propagation of light in the material using simulation and development of a computer program to simulate the propagation of UV radiation in WPSC block. A separate computer program in the Object Pascal language was compiled to study the model. The program is designed to simulate two-dimensional approximation of infrared, visible, ultraviolet radiation propagation in wood polymer-sand composite. The program is applicable in a wide range of concentrations of the composite components, for different optical absorption coefficients of the components, depending on the wavelength of the radiation. Concentrations, optical properties of the components, and lighting conditions can be specified in the text of the program. The results of the program are the structure of the composite as a random uniform distribution of wood and sand fragments in a polymer matrix, a cartogram and a graph of the intensity distribution in the composite specimen. The result has been obtained: penetration depth of destructive UV radiation is about 1.5 mm at an optimal concentration of the components CW=45%, CPI=35%, CSa = 20%.

木材聚合物-砂复合材料中光传播的建模

研究的主题是木材聚合物-砂复合材料(WPSC)及其物理和机械性能的研究。在这种情况下,它是光在材料中的传播,使用模拟和开发计算机程序来模拟 WPSC 块中 UV 辐射的传播。编译了一个使用 Object Pascal 语言的单独计算机程序来研究该模型。该程序旨在模拟木材聚合物-砂复合材料中红外、可见光、紫外辐射传播的二维近似。该程序适用于各种浓度的复合成分,根据辐射的波长,成分的光吸收系数不同。可以在程序的文本中指定浓度、组件的光学特性和照明条件。该程序的结果是复合材料的结构,即在聚合物基质中随机均匀分布的木材和沙子碎片,以及复合材料样品中的强度分布图和图表。得到的结果是:在 C 组分的最佳浓度下,破坏性紫外线辐射的穿透深度约为 1.5 毫米W =45%,C PI =35%,C Sa = 20%。
