    Studies on the wood fiber-rock wool composites

    • 摘要: 该文探讨了制造木纤维/岩棉纤维复合材料时,纤维长度、岩棉纤维用量、密度、施胶量、热压温度、热压时间等因素对复合材料力学性能的影响.研究结果表明:将岩棉纤维和木纤维混合,制造木纤维/岩棉纤维复合材料是可行的;木纤维长度、产品密度、岩棉纤维用量是影响复合板材力学性能和阻燃性能的主要因素;随着木纤维长度的增大,产品的静曲强度提高、内结合强度降低;随着密度的提高,产品的力学性能呈线性比例增大;随着岩棉纤维用量的加大,产品的力学性能呈线性比例降低、阻燃性能呈线性比例增大;在实验选定的参数范围内,施胶量、热压温度、热压时间对产品力学性能和阻燃性能的影响不明显.

       

      Abstract: The thesis probed into the factors influencing the mechanical properties of composite material,such as fiber length,dosage of rock wool,density,resin content,temperature of hot pressing and hot pressing time,etc.when using rock wool and wood fiber to make wood fiber-rock wool composites.The study shows that it is feasible to make wood fiber-rock wool composites by blending rock wool and wood fiber.The length of wood fiber,density of the products,dosage of rock wool are the main factors influencing the mechanical and fire-retardant properties of composites.With the increase of wood fiber length,the static bending strength of products increases and the internal bond strength decreases.When density increases,the mechanical properties of the products heighten linearly.When the dosage of rock wool increases,the mechanical properties of products weaken linearly and the fire-retardant performance of the products heightens linearly.Within the range of parameters which are selected for the experiment,the influence of resin content,temperature of hot pressing and hot pressing time on the mechanical properties and fire-retardant performance of the products is not obvious.
