This proposal addresses the topic of Consolidation of Thermoplastic hybrid yarn materials -ConThP, consisting of thermopl astic matrix fibres and reinforcing carbon fibres. The ConThP project is about the implementation of a consolidation approach into finite element analysis which enables to use hybrid yarn materials in conjunction to complex toolings to enable integral design concepts with a high structural performance.The objective is to develop a constitutive 3D approach which considers air evacuation, fibre bed compaction, resin flow and void formation in a model suitable for application in finite element analysis. This model will cover high performance thermoplastic material and is applicable for load carrying aerospace structures. The results will support the phase of design and process development and create opportunities for an efficient manufacture of complex shaped high performance fibre reinforced thermoplastics from hybrid textiles.Considering consolidation within the design process will allow applying knowledge based procedures, which will reduce development time and costs in the production of composite parts. Furthermore, using a consolidation prediction rather than empirical based rules allows an increased flexibility in the part design. The integrative consolidation model will be validated by the manufacture of a complex shaped component.

该提案涉及热塑性混合纱线材料的固结-ConThP，由热塑性基质纤维和增强碳纤维组成。ConThP项目是关于在有限元分析中实施一种固结方法，该方法能够将混合纱线材料与复杂的工具结合使用，以实现具有高结构性能的整体设计概念。其目标是开发一种三维结构方法，该方法在一个适合有限元分析应用的模型中考虑空气排出、纤维床压实、树脂流动和空隙形成。该模型将涵盖高性能热塑性材料，适用于承载航空航天结构。研究结果将为设计和工艺开发阶段提供支持，并为从混合纺织品中高效制造复杂形状的高性能纤维增强热塑性塑料创造机会。在设计过程中考虑合并将允许应用基于知识的程序，这将减少复合材料部件生产的开发时间和成本。此外，使用合并预测而不是基于经验的规则允许部件设计中的增加的灵活性。通过复杂形状构件的制造验证了综合固结模型的正确性。
