凯夫拉纤维模量高、韧性好,七十年代以来已作为一种轻质高强材料广泛应用,然而亦给机械加工带来了新问题。经实验研究证明,在夫凯拉复合材料的最外层铺放比较脆的背衬材料可改善加工性能,可使用通用刀具进行切割、钻孔、扩孔;采用低的刀具转速有助于减轻环境污染。 Kevlar has high fiber modulus and good toughness, and has been widely used as a lightweight and high-strength material since the 1970s. However, it poses new problems for machining. Experimental studies have shown that the relatively brittle backing material can be applied to the outermost layer of the Buckerard composite to improve the processability, which can be cut, drilled and reamed using universal tools. The use of low tool speeds helps to reduce Environmental pollution.
