通过优化针尖形态，采用图像采集装置获取针尖形态外形曲线，进行不同针尖形态下含或不含金属粉体碳布穿刺后性能测试，通过碳布穿刺的损伤情况，分析针尖形态优化结果。研究表明，在不影响穿刺工艺的条件下，通过针尖形态优化，针尖曲线幂次近似2．0曲线的钢针穿刺的碳布拉伸断裂强力最高，碳布穿刺损伤最小。
通過優化針尖形態，採用圖像採集裝置穫取針尖形態外形麯線，進行不同針尖形態下含或不含金屬粉體碳佈穿刺後性能測試，通過碳佈穿刺的損傷情況，分析針尖形態優化結果。研究錶明，在不影響穿刺工藝的條件下，通過針尖形態優化，針尖麯線冪次近似2．0麯線的鋼針穿刺的碳佈拉伸斷裂彊力最高，碳佈穿刺損傷最小。

The needle tip shape was optimized to reduce the damage of carbon fabrics containing metal powder. In the study, the prop- erties of pierced carbon fabrics with or without metal powder were tested, and the result of needle tip shape optimization was judged by the damage of the pierced carbon fabrics. The study showed that, provided the piercing process was not affected, the carbon fabrics pierced with optimized steel needles with an approximate 2.0 power of tip curve exhibited the highest tensile breaking strength and the lowest piercing damage.
