亚麻增强热塑性树脂复合材料板材的研究与应用

以亚麻纤维为增强体,与聚丙烯(PP)纤维按一定比例进行混合,然后制备加捻纱及PP长丝包覆的包覆纱,并利用机织工艺织成二维机织布作为复合材料的预制铺层.采用层合热压方法制备PP/亚麻纤维复合材料板材.通过对板材弯曲性能的测试及分析,研究了制备工艺、纱线结构及亚麻纤维含量等因素对复合材料弯曲性能的影响.

RESEARCH ON FLAX FIBER REINFORCED THERMOPLASTIC COMPOSITE

Flax fiber was used as reinforcing material to commingle with polypropylene(PP)fiber to realize the mixture of two materials at the stage of yarn,meanwhile,PP filaments were introduced to produce a core-spun yarn with PP/flax as core and PP filament as outer sheath.The commingled yarns were woven into 2-D fabric which was used as the prefabricated material.The composite laminates were prepared by hot press technology.The effects of manufacture technology,yarn structure and fiber weight fraction on flexural ...
