标准范围

ISO 14127:2008规定了根据树脂、纤维和复合材料的密度以及复合材料中纤维的质量计算碳纤维增强复合材料的树脂、纤维和空隙含量的方法（方法a），以及根据复合材料的厚度计算纤维含量的方法（方法B）。方法A规定了测定复合材料中纤维质量的三种不同树脂去除程序（即燃烧程序、硝酸消化程序和硫酸和过氧化氢混合物消化程序）。选择使用的程序时，应考虑复合材料中所用树脂的燃烧性、分解能力和相关树脂的类型。应注意的是，当填充树脂可能会阻止树脂完全溶解和/或燃烧时，方法A的适用性有限。方法B（厚度测量方法）仅适用于由单位面积已知纤维质量的预浸料模制的层压板。

ISO 14127:2008 specifies methods for calculating the resin, fibre and void contents of a carbon-fibre-reinforced composite from the densities of the resin, the fibre and the composite and the mass of fibre in the composite (method A) and for calculating the fibre content from the thickness of the composite (method B).Method A specifies three different resin removal procedures for the determination of the mass of fibre in the composite (viz a combustion procedure, a procedure by digestion in nitric acid and a procedure by digestion in a mixture of sulfuric acid and hydrogen peroxide). The selection of the procedure to be used is made by considering the combustibility of the resin used in the composite, its ability to decompose and the type of resin concerned. It should be noted that method A is only of limited applicability when filled resins are present that could prevent complete dissolution and/or combustibility of the resin.Method B (thickness measurement method) is only applicable to laminates moulded from prepregs of known fibre mass per unit area.
