本数据集涉及高韧性无机纤维束（tough inorganic fiber bundles）的处理方法，包含两类核心工艺：
1. 开松分散工艺：对多束高韧性无机纤维束进行开松处理，使纤维可分散于液态浆料（liquid slurry）中，进而形成均匀纤维聚集体（homogeneous fiber aggregate）；其中所述高韧性无机纤维的压溃沉降体积（Crush Settle Volume）大于250mL，可选条件为其压溃沉降体积大于450mL。
2. 稀释分散工艺：将多束高韧性无机纤维束分散于含有占比约0.1%~2%（可选范围为0.1%~1%）稀释剂（diluent）的浆料中，该体系可有效形成均匀纤维聚集体；其中所述高韧性无机纤维的压溃沉降体积（Crush Settle Volume）大于250mL，可选条件为其压溃沉降体积大于450mL。
