预浸渍编织材料的手工铺层仍然是复合材料制造业的重要组成部分，需要人类劳动力的技能和经验来将平面层形成复杂的形状。它能够生产高性能和复杂的零件，但可能是一个昂贵和可变的过程。尽管它很重要，但对工人在铺层过程中操纵复合材料平板成形的实际方法和技术的研究似乎很少。这项工作提出了第一个已知的详细研究的方法和技术使用的层压机。四名参与者躺在15个不同形状的模具上，这些模具复制了复合材料部件的常见特征。上篮中使用的动作被分为八种不同的技术。这些技术在不同几何形状、斜坡角度、半径和悬垂路径任务中的使用是通过人体工程学领域的视频分析技术确定的。这揭示了特定功能和技术之间的紧密联系，揭示了一种系统的布局方法。这使得第一步朝着生产设计制造知识库围绕手上篮。然后，这可以用于通知分层过程的发展，改进培训方法，并协助设计未来的自动化解决方案。
The hand layup of pre-impregnated woven materials is still a large part of the composite manufacturing industry, requiring the skills and experience of a human workforce to form flat plies into complex shapes. It is capable of producing high performance and complex parts, but can be an expensive and variable process. Despite its importance, there appears to have been very little research into the actual methods and techniques used by workers to manipulate flat sheets of composite material into shape during layup. This work presents the first known detailed study of the approach and techniques used by laminators. Four participants laid up onto 15 different shaped molds that replicated features commonly found on composite components. The actions used in layup were grouped into eight distinct techniques. Use of these techniques across tasks of different geometry, ramp angles, radii and drape path was identified using video analysis techniques from the ergonomics field. This revealed strong links between specific features and techniques, revealing a systematic approach to layup. This has enabled the first step toward producing a design for manufacture knowledge base surrounding hand layup. This could then be used to inform the development of the layup process, improve training methods and assist in the design of future automated solutions.
