摘　　要：将3D间隔织物与聚氨酯基体相复合,制备成3D间隔织物增强聚氨酯基复合材料。对不同厚度、孔隙率和材料的3D间隔织物增强聚氨酯基复合材料试样进行了透气性、透湿性和压缩性能的测试,分析了参数对试样性能的影响。结果表明:孔隙率越高,厚度越薄,试样的透气性越好,而被间隔织物增强的试样透气性变差;孔隙率越高,厚度越厚,试样的透湿性越差,试样的屈服强度越低,抗压性能越差,更容易产生塑性变形,间隔织物可以增强聚氨酯基体的抗压性能。The 3 D spacer fabric was combined with the polyurethane matrix to prepare 3 D spacer fabric reinforced polyurethanebased composites.The air permeability,moisture permeability and compression performance of the 3 D spacer fabric reinforced polyurethane-based composite samples with different thickness,porosity and materials were tested,and the influence of the parameters on the performance of the sample was analyzed.The results showed that the higher the porosity and the thinner the thickness,the better the air permeability of the sample,while the air permeability of the sample reinforced by the spacer fabric become worse;the higher the porosity and the thicker the thickness,the worse the moisture permeability of the sample;the lower the yield strength of the sample,the worse the compressive performance,and the easier it was to produce plastic deformation. The results also indicated that the spacer fabric could enhance the compression performance of the polyurethane matrix.
