Collaborative effort between the Center for Composite Materials (UD-CCM), and the Institut für Textil-technik der RWTH Aachen University (ITA) have shown that z-fiber reinforced composites can increase the thermal conductivity (TC) ten times with the potential to have equivalent thermal properties compared to metals while maintaining all the conventional benefits of composites. Nevertheless fundamental under-standing of TC behavior of three-dimensional reinforced composites is not fully comprehended and is the key to optimization. ITA and UD-CCM will together extend their fundamental research effort to establish a model base enabling design for a variety of applications that will lead to a better understanding of the mechanisms to improve the through-thickness properties. ITA will develop suitable yarn structures for pitch based carbon fibers, model and design integrated textile structure, manufacture textile preforms with integrated thermal conductive yarns and test and characterize integrated textile structures. UD-CCM will develop an analytical and finite element model, modify resin injection methods and measure the TC. The possibilities offered for the formation of yarn taking into account the boundary conditions of the yarns such as fiber brittleness, yarn spacing and yarn diameter will be explored and thoroughly investigated in this project.

复合材料中心（UD-CCM）和RWTH亚琛大学纺织技术研究所（ITA）之间的合作表明，z纤维增强复合材料可以将热导率（TC）提高十倍，与金属相比具有相同的热性能，同时保持复合材料的所有传统优势。然而，对三维增强复合材料热变形行为的基本认识还没有完全理解，这是优化的关键。ITA和UD-CCM将共同扩展他们的基础研究工作，以建立一个模型库，使设计能够用于各种应用，从而更好地理解提高全厚度性能的机制。ITA将为沥青基碳纤维开发合适的纱线结构，建模和设计集成纺织结构，制造具有集成导热纱线的纺织预成型件，并测试和表征集成纺织结构。UD-CCM将开发分析和有限元模型，修改树脂注射方法并测量TC。在这个项目中，将探索并彻底研究考虑到纱线的边界条件（如纤维脆性、纱线间距和纱线直径）的纱线形成的可能性。
