| 摘要: | 本實驗主要研究碳纖維複雜組織織物的耐熱性能，首先以碳纖維爲經紗、聚酯長絲/聚丙烯長絲爲緯紗，織製經二重組織織物和上下接結組織織物，然後對織物進行熱處理，測量比較熱處理前後織物的尺寸、斷裂伸長率和斷裂强力的變化。結果得知100℃下，織物性能基本不變；200℃下，織物經緯向的各個性能發生變化。研究測試織物的耐熱性能，更加明確了其使用範圍及限制，爲進一步研究織物在工程用木質複合材料上的應用提供依據。
The heat resistant properties of the carbon fiber composed weave fabric were mainly studied by this experiment. Firstly warp rib weave fabric and face warp stitching duplex weave fabric were woven with carbon fiber as warp yarn and polyester filament/polypropylene filament yarn as weft, and then heated at different temperature, at the last, tested and compared dimensional shrinkage, elongation at break the and breaking strength of the fabric before and after heat treatment. The results show that under 100 ℃, the performances basically remain unchanged; Under 200 ℃, the performances of warp/weft change a litter. Through the study of heat resistance, its scope of application and limitation became more clearly. This provides the foundation for further research on the application of the composed weave fabric in the engineered wood composite materials. |
