摘要
Abstract
Three kinds of carbon nanotubes, carboxylated carbon nanotubes (MWCNTs-COOH), diamino biphenyl methane modified carbon nanotubes (MWCNTs-DDM) and boric acid modified carbon nanotubes (MWCNTs-Borate),are prepared by covalent grafting method. The modified MWCNTs with phenolic resin (BPR) are composed by in-situ polymerization. These modified carbon nanotubes (mMWCNTs) are added into the phenolic resin-based friction materials. The results show that the stability of the friction coefficient of friction material is improved, wear rate is reduced and thermal recession is improved after adding the mMWCNTs. Lwt% of the MWCNTs-Borate brings the largest improvement, wear rate is decreased by 43.2%, decline rate of the friction coefficient and wear rate are only 10.3% and 28.6%,also, the friction surface remains intact.关键词
