Abstract

Abstract Carbon fiber-reinforced thermoplastics offer the possibility for short lead times and dustless assembly in aerospace applications. However, their great potential for efficient processing to date is not entirely exploited. At the Center for Lightweight Production Technology (ZLP) in Augsburg smart automation of thermoplastic composite production is investigated. To assess the overall process chain a sine wave beam designed as crash-absorber serves as demonstrator. The production process from as-delivered material to final assembly is presented. In addition to non-destructive testing at the end of the value adding process chain, production-integration quality assurance, and process characterization serve to evaluate each process step. In this context, water-coupled ultrasonic testing as an established method in aerospace production is used to assess the degree of consolidation after vacuum consolidation and press-forming. Thus, quality issues and crucial process parameters can be identified and optimized to improve robustness.

波纹复合材料:生产一体化的质量保证在碳纤维增强热塑性正弦波梁生产

碳纤维增强热塑性塑料在航空航天应用中提供了缩短交货时间和无尘组装的可能性。然而，迄今为止，它们在有效处理方面的巨大潜力尚未得到充分利用。在奥格斯堡的轻量化生产技术中心(ZLP)，热塑性复合材料生产的智能自动化进行了研究。为了评估整个过程链，一个设计为碰撞减震器的正弦波束作为演示。介绍了从交货到总装的生产过程。除了在增值工艺链末端的无损检测之外，生产集成质量保证和工艺表征有助于评估每个工艺步骤。在这种情况下，水耦合超声测试作为航空航天生产中的既定方法，用于评估真空固结和压制成型后的固结程度。因此，质量问题和关键工艺参数可以识别和优化，以提高鲁棒性。
