当前复合材料制造研究的两个主要目标是铺层的自动化和真空袋固化（VBO）的发展。目前，经常需要定期的压实循环以获得良好的铺设质量，并且需要高压釜固化以获得足够的固化层压板质量。本文将介绍一个专门建造的自动化铺层模拟器，已开发提供非常好的控制铺层的数据。结果表明，高质量的层压板可以制造没有压实周期和固化下，真空袋没有额外的压力，充分压实每个层在铺叠。这是通过使用超出当前一代ATL/AFP机器可达到的范围的铺层温度和压力来实现的，并提出了开发策略以实现更有能力的设备的开发。(c)2012爱思唯尔有限公司保留所有权利。
Two major targets of current composites manufacturing research are the automation of lay-up and the development of vacuum bag only (VBO) cure. Currently regular debulk cycles are often required to obtain good as-laid quality, and autoclave cure is needed to obtain an adequate cured laminate quality. This paper will present data from a purpose-built automated lay-up simulator that has been developed to offer very well controlled lay-up. It is shown that high quality laminates may be manufactured without debulk cycles and cured under a vacuum bag without additional pressure by sufficiently compacting each ply during layup. This is achieved using layup temperatures and pressures falling outside the range attainable by the current generation of ATL/AFP machines and a development strategy is proposed to achieve the development of more capable equipment.
