摘要
为了获得轻质高强的复合材料,本文以沙生灌木(柠条)纤维为原料,以粗异氰酸酯为胶粘剂,以十二烷基磺酸钠为发泡剂,采用聚合物发泡技术与人造板工艺技术结合制备轻质复合材料,通过发泡手段使材料密度降低的同时提高材料的物理力学性能。重点研究发泡对复合材料力学性能的影响。研究结果表明:对生物质纤维基复合材料进行发泡可以有效提高材料的物理力学性能。经方差和极差分析知,本研究F值的最佳工艺条件为:施胶量为25%,发泡剂加量10%、复合温度165℃、复合时间40 s/mm。
In order to obtain the lightweight composites.In this paper,process and properties of hightweight composites were studied with Caragana korshinskii fiber as raw materials,PAPI as adhesive,SDS as foaming agent.An investigation had been performed on hightweight composites using combination of polymer foaming technology and noweave technology.Causes the material density through the foaming method to reduce simultaneously enhances the material physical mechanics properties.The key research becomes foaming to materials mechanics properties influence.The results showed that the physical and mechanical properties of hightweight composites can improve though foaming.Based on the variance analysis and maximum difference analysis,significance test shows the optimum conditions for content of bonding agent of 25%,foaming agent of 10% by weight,a hot-pressing temperature of 165℃ and a hot-pressing time of 40s/mm.
