Consolidation of Thermoplastic hybrid yarn materials

本提案涉及热塑性混杂纱线材料ConThP的固结问题，该混杂纱线材料由热塑性基质纤维和增强碳纤维组成。ConThP项目是将固结方法应用到有限元分析中，能够将混杂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。目标是开发一种本构3D方法，在适用于有限元分析的模型中考虑空气排空、纤维层压实、树脂流动和空洞形成。该模型将覆盖高性能热塑性材料，适用于承重航天结构。结果将支持设计和工艺开发阶段，并为从混合织物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。考虑到设计过程中的整合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可以提高部件设计的灵活性。综合固结模型将通过制造一个复杂形状的部件进行验证。

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.
