包芯编带纱的制造工艺及结构参数

The Production Technology and Structure Parameter of Micro-braided Yarn

对 4种具有不同混纺比和不同玻璃纱特数的GF PP包芯编带纱的加工工艺、几何结构进行了分析和研究 ;建立了编织角、纤维混纺比、编织纱对芯纱的包覆紧密度等参数之间的关系。通过电子显微镜观察了包芯编带纱的几何结构并计算了在由GF PP包芯编带纱制成的单向复合材料中玻璃纤维的孔隙率和直径。

The author analyses and studies the production techndogy and structure of the micro-braided yarn.The relationship between the fiber orientation angle and blend rate as well as bound force was established.Yarn geometries were also studied through microscope observation.
