编织成型是一种复合材料的制造工艺，其中编织机与拉丝模耦合以连续生产具有恒定横截面和离轴纤维取向的梁。本研究提出了一个几何模型的三轴编织，它允许设计的编织预成型件，实现正确的填充的pulmonary模具在同一时间，因为它限制了纤维摩擦模具壁。列出了典型的设计参数，并用于制造编织挤出的热塑性复合材料梁，其中纤维相对于梁轴以690度和00度排列。拉伸力学特性和横截面观察。(C)2012爱思唯尔有限公司保留所有权利。
Braid-trusion is a manufacturing process for composite materials in which a braiding machine is coupled with a pultrusion die to continuously produce beams with constant cross-section and off-axis fiber orientation. This study presents a geometrical model of the tri-axial braid which allows the design of braided preforms that achieve correct filling of the pultrusion die at the same time as it limits fiber friction on die walls. The typic design parameters are listed and used for the manufacturing of a braid-truded thermoplastic composite beam where fibers are aligned at 690 as well as 00 with respect to the beam axis. Tensile mechanical characterization and cross-section observations are also presented. (C) 2012 Elsevier Ltd. All rights reserved.
