The　bamboo　fibers　were　added　into　resin　matrix　composite　as　the　main　reinforcement　in　order　to　develop　a　new　kind　of　friction　material　free　of　asbestos.　By　using　thermogravimetric　analysis,　constant　speed　friction　test　and　worn　surface　morphology　observation,　the　effect　of　amount　of　bamboo　fiber　in　the　composite　on　the　tribological　performance　at　different　temperatures　was　investigated.　The　results　show　that　the　addition　of　bamboo　fibers　in　the　composites　improved　the　friction　and　wear　properties　and　reduced　the　braking　noise　and　vibration.　Carbonation　and　volatilization　of　bamboo　fibers　occurred　at　temperature　higher　than　the　pyrolysis　temperature.　In　this　study,　the　braking　samples　with　13%　bamboo　fiber　showed　stable　friction　coefficients　and　low　wear　rates.　High　amount　of　bamboo　fibers　resulted　in　difficulty　in　preparation　process,　carbonation　and　volatilization　of　bamboo　fibers　at　elevated　temperature　and　de-bonding　from　the　matrix.　As　a　result,　the　friction　properties　of　the　composites　were　degraded　significantly.
