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.

该提案介绍了热塑性混合纱线材料的合并主题-Conthp，由热孔基矩阵纤维和增强碳纤维组成。 CONTHP项目是关于实施合并方法中有限元分析的实施，该方法使得可以将混合纱线材料结合到复杂的工具，以使整体设计概念具有高结构性能。该目标是开发一种组成型3D方法，以认可空气空气空气疏散，纤维床压实，树脂流量和空隙形成，适用于有限元分析中的应用。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的负载。结果将支持设计和过程开发的阶段，并为从混合纺织品中有效地生产复杂形状的高性能增强热塑性塑料。在设计过程中考虑合并将允许采用基于知识的程序，这将减少开发时间和成本在复合零件的生产中。此外，使用合并预测而不是基于经验的规则可以提高零件设计的灵活性。集成整合模型将通过制造复杂形成组件来验证。
