分别制备不同比例的亚麻/HDPE复合材料和亚麻/PP复合材料，检测其物理性能。结果表明，亚麻复合材料的密度和吸水率在不添加偶联剂时最大，添加偶联剂后先减后增，添加到9%时有小幅增大。亚麻/PP复合材料与亚麻/HDPE复合材料相比，密度小但吸水率大。%Flax/HDPE composite and flax/PP composite with different proportions are prepared respectively to detect their physical properties,with the result showing that the density and water absorption rate of flax composite are the highest when no coupling agent is added and decrease first and then increase when coupling agent is added,with small increase at 9%. Compared with flax/HDPE composite,flax/PP composite has low density and high water absorption rate.
