梭织/针织复合织物增强聚氨酯基复合材料性能

Properties of Woven/Knitted Fabric Reinforced Polyurethane Composites

选用经编间隔织物与碳纤维梭织物作为增强体,聚氨酯泡沫作为基体材料制备复合材料。探讨织物厚度、表面结构和碳纤维梭织物加入与否对复合材料的透湿性能、透气性能、压缩性能的影响。结果表明:在厚度相同的情况下,双面大网孔的压缩性能和透气透湿性能优于双面小网孔;单面大网孔的透气透湿性能优于单面小网孔,但压缩性能略差。在间隔层厚度和织物网孔相同的情况下,单面双层复合材料的压缩性能和透气性能优于单面单层复合材料。

The warp knitted spacer fabric and carbon fiber woven fabric were used as reinforcement and polyurethane foam was used as matrix material to prepare the composite material. The influence of fabric thickness, fabric surface structure and the addition of carbon fiber woven fabric on moisture permeability, air permeability and compression properties of the composites was discussed. The results showed that under the condition of the same thickness, the compressibility and moisture permeability of large double-sided mesh were better than those of small double-sided mesh. The air permeability and moisture permeability of single-sided large mesh was better than that of single-sided small mesh, but the compression performance was slightly worse. When the spacer thickness and fabric mesh were same, the compressibility and permeability of single-sided double-layer composite were better than that of single-sided single-layer composites.
