一、问题开始检测作为汽车刹车材料的CFRC(碳纤维增强碳)复合材料的原因之一是来自生产非石棉摩擦件的政府和工业研究机构的要求。因为在过去的数次测试结果中已表明石棉纤维具有高致癌性危险系数的临界直径/长度较(见图1)。
I. ISSUE One of the reasons to start testing CFRC (carbon fiber reinforced carbon) composites as automotive brake materials came from the requirements of government and industrial research institutes producing non-asbestos friction materials. Because in the past several test results it has been shown that asbestos fibers have a critical diameter / length of high carcinogenicity hazard ratio (see Figure 1).
