Composite materials which are reinforced with 3D warp interlock fabrics have outstanding mechanical properties such as higher delamination resistance, ballistic damage resistance and impact damage tolerance by means of their improved structural properties. Textile reinforcements are exposed to large deformations in the production stage of composite materials which have complex shape. Although good formability properties of 3D warp interlock fabrics in forming process were already proven by recent studies, further information is needed to elucidate forming behaviours of multi-layer fabrics which is produced with high stiffness yarns like carbon. In this study, 3D warp interlock carbon fabrics were produced on a prototype weaving loom and the same carbon yarn was used in two fabric directions with equal number of yarn densities. Fabrics were differentiated with regard to the presence of stuffer warp yarn, weave pattern and parameters of binding warp yarn which are angle and depth. Therefore, the effect of fabric architecture on the mechanical and formability properties of 3D warp interlock carbon fabrics could be clarified. Three different breaking behaviours of fabrics were detected and they were correlated with crimp percentages of yarn groups. In addition, the bending and shear deformations were analysed in view of parameters of fabric architectures. Two distinct forming behaviours of fabrics were determined according to the distribution of deformation areas on fabrics. Moreover, the optimal structure was identified for forming process considering the fabric architecture.

复合材料复杂形状的3D经编互锁碳纤维织物的力学和成形性能研究

用3D经线互锁织物增强的复合材料具有出色的机械性能,例如,较高的抗分层性,耐冲击性和耐冲击损伤性,均归因于其改进的结构性能。在形状复杂的复合材料的生产阶段,纺织品增强材料会承受较大的变形。尽管最近的研究已经证明了3D经线互锁织物在成型过程中的良好成型性,但仍需要进一步的信息来阐明用高刚度纱线(如碳纤维)生产的多层织物的成型性能。在这项研究中,在原型织机上生产了3D经编互锁碳纤维织物,并且在两个织物方向上使用了相同的碳纤维纱,并且纱线密度相同。根据填充毛经纱的存在,编织图案和粘合经纱的参数(角度和深度)来区分织物。因此,可以弄清楚织物结构对3D翘曲互锁碳纤维织物的机械性能和成型性的影响。检测到织物的三种不同的断裂行为,它们与纱线组的卷曲率相关。另外,根据织物结构的参数分析了弯曲和剪切变形。根据织物上变形区域的分布,确定了两种不同的织物成型行为。此外,考虑到织物结构,确定了用于成形过程的最佳结构。经纱的织造图案和参数(角度和深度)。因此,可以弄清楚织物结构对3D翘曲互锁碳纤维织物的机械性能和成型性的影响。检测到织物的三种不同的断裂行为,它们与纱线组的卷曲率相关。另外,还根据织物结构的参数分析了弯曲和剪切变形。根据织物上变形区域的分布,确定了两种不同的织物成型行为。此外,考虑到织物结构,确定了用于成形过程的最佳结构。经纱的织造图案和参数(角度和深度)。因此,可以弄清楚织物结构对3D翘曲互锁碳纤维织物的机械性能和成型性的影响。检测到织物的三种不同的断裂行为,它们与纱线组的卷曲率相关。另外,根据织物结构的参数分析了弯曲和剪切变形。根据织物上变形区域的分布,确定了两种不同的织物成型行为。此外,考虑到织物结构,确定了用于成形过程的最佳结构。可以弄清楚织物结构对3D翘曲互锁碳纤维织物的机械性能和成型性的影响。检测到织物的三种不同的断裂行为,它们与纱线组的卷曲率相关。另外,根据织物结构的参数分析了弯曲和剪切变形。根据织物上变形区域的分布,确定了两种不同的织物成型行为。此外,考虑到织物结构,确定了用于成形过程的最佳结构。可以弄清楚织物结构对3D翘曲互锁碳纤维织物的机械性能和成型性的影响。检测到织物的三种不同的断裂行为,它们与纱线组的卷曲率相关。另外,根据织物结构的参数分析了弯曲和剪切变形。根据织物上变形区域的分布,确定了两种不同的织物成型行为。此外,考虑到织物结构,确定了用于成形过程的最佳结构。根据织物上变形区域的分布,确定了两种不同的织物成型行为。此外,考虑到织物结构,确定了用于成形过程的最佳结构。根据织物上变形区域的分布,确定了两种不同的织物成型行为。此外,考虑到织物结构,确定了用于成形过程的最佳结构。
