Mechanical Properties of Milled Glass Fiber Reinforced Rigid Polyurethane Foam

  • 摘要: 研究了磨碎玻璃纤维(GF)增强硬质聚氨酯泡沫塑料(RRPUF)的压缩强度和冲击韧性,探讨了GF含量及粒度、GF偶联处理对RRPUF压缩性能的影响。发现RRPUF的压缩强度随着磨碎玻纤粒度的细化而增大;当添加量为20%(w)时达到最大值;对玻纤进行偶联处理后RRPUF的增强效果较好,且在添加量为15%(w)时压缩强度达到最大值;冲击韧性随着磨碎玻纤添加量的增加而下降。
    Abstract: The mechanical properties and impact energy of milled glass fiber (GF) reinforced rigid polyurethane foam was investigated in the present article,in which the general factors such as the concentration,particle size and surface-treatment of GF influencing the mechanical properties of RRPUF were discussed.It was indicated that compressive strength of RRPUF was increased with GF dimension decrease and the reinforced effect is best when the fiber -content is 20%.The reinforced effect of surface-treated GF was better than that of untreated GF and when the fiber-content is 15% the reinforced effect is best.The impact toughness of RRPUF was decreased with fiber-content increase.
