用芳纶、聚苯并恶唑（PBO）、聚乙烯和聚酯纤维对碳纤维预制件进行三维增强，并真空注射环氧树脂。用统计方法分析了缝合线分布和缝合工艺参数对Ⅰ型层间断裂韧性的影响。针脚分布有一个小的影响，但三维线张力必须仔细选择，以获得最佳的机械性能。PBO纤维在断裂韧性方面提供了最大的改善。芳纶纤维的3D增强使拉伸和弯曲性能降低了3- 8%。TFP的低速冲击损伤大于织物，但小于胶带层压板。冲击后压缩强度在某些情况下通过3D增强部分地增加，但在其他条件下没有发现改善。
Tailored fibre placement (TFP) preforms made of carbon fibre were 3D reinforced with aramid, polybenzoxazol (PBO), polyethylene and polyester fibres and vacuum injected with epoxy resin. The effects of stitch distribution and stitching process parameters on Mode I interlaminar fracture toughness were analysed using a statistical approach. Stitch distribution had a minor effect but 3D thread tension had to be carefully chosen to gain optimum mechanical properties. PBO fibre provided the most improvement in fracture toughness. 3D reinforcing with aramid fibre reduced tensile and flexural properties by 3-8%. Low velocity impact damage in TFP was larger than in fabric but smaller than in tape laminates. Compression-after-impact strength was partly increased by 3D reinforcing in some circumstances but no improvement was found under other conditions.
