三维整体经编夹芯结构预制件的制备工艺

在传统经编间隔织物研究的基础上进行玻纤经编间隔织物的研究，包括玻纤原料的选用、织物组织结构设计、上机试验编织的研究等。结果表明：优化设计经编间隔织物结构，选用细度较小、捻度较小的玻璃纤维纱并在编织过程中对玻纤采取适当的润滑处理，可大大减小玻纤因脆性大，起静电，易钩毛引起的断纱。同时，上机织造时选择利于编织的成圈机件配置，优化织针形状，合理调节上机过程中牵拉与送经参数的配置关系，选用较大的牵拉角度，可以较好的改善玻纤的编织性能，提高三维整体经编预制件的成型质量，为实际生产提供参考价值。

Study on preparation process of 3-D sandwich structures of warp knitting reinforced materials

The study on 3-D glass fiber sand-wich structures of warp knitting fabric based on the traditional warp knitting, including the study on the selection of raw materials of glass fiber ,fabric structure design, the weaving machine test and etc. The results show that optimize design of warp knitting fabric structure, select a smaller fineness, use lesser twist glass fiber yarn and in weaving process take proper lubrication processing for glass fiber, which can greatly reduce glass fiber for brittleness, electrostatic and easy to hook hair which cause of the yarn breakage. At the same time, choose woven knitting elements configuration, optimize the knitting shape, reasonable adjustment of the configuration parameters between stretch and warp, choose larger force angle, which can better improve the glass fiber woven performance, improve the quality shaping of 3-D sand-wich structures warp knitting, and make a value reference for the practical production.
