木質素纖維
木質素纖維(WCF)是由甲基纖維素加工而成。其分散性能優良,特別適用於冷壓成型的摩擦材料;在300℃左右直接碳化,類似於碳纖維,起到穩定摩擦系數的的作用;具有生物降解性,對人和環境安全。
The wood cellulose fibre
The wood cellulose fibre is made from methyl cellulose. Its scattering capacity is excellent, particularly suitable for friction material of cold-pressure moulding. It may be carbonized at about 300℃, the fibre is similar to carbon fibre. It has stable in friction coefficient. It may be biodegradable, so it is safe and harmless to environment.
