Bamboo　fiber　was　treated　by　PVC　coating,　and　applied　to　reinforce　resin　matrix　friction　composite.　The　effects　of　PVC　coating　on　tribological　performance　of　bamboo　fiber　reinforced　composites　were　investigated　by　the　constant　speed　friction　test,　SEM　observation,　energy　dispersive　spectroscopy　(EDS)　and　thermogravimetry　(TG)　analysis.　The　results　show　that,　the　PVC　coated　bamboo　fibers　can　significantly　improve　the　tribological　properties　of　friction　materials,　especially　the　friction　coefficient　at　elevated　temperature.　The　samples　treated　by　2%　PVC　solution　for　20　min　have　excellent　friction　and　wear　properties.　Bamboo　fibers　PVC　coated　form　an　uniform　PVC　composite　layer　on　the　surface,　which　enhances　the　interface　bonding　capacity　between　bamboo　fiber　and　resin　matrix.　The　coated　bamboo　fibers　can　reinforce　the　substrate　at　elevated　temperature,　so　that　the　tribological　performance　of　the　composite　is　improved.　©,　2015,　Editorial　Office　of　Transactions　of　Materials　and　Heat　Treatment.　All　right　reserved.
