In　order　to　render　brake　composite　environmental　friendly　and　promote　waste　materials　recycling,　different　amount　of　rice　husk　powder,　an　agricultural　by-product,　were　added　as　fillers,　modified　phenolic　resin　as　matrix,　bamboo　fiber,　magnesium　whisker　and　calcium　sulfate　whisker　as　reinforced　phase,　graphite　and　copper　powder　as　friction　performance　regulator.　Hot　pressing　molding　was　used　to　make　a　new　type　of　environment-friendly　friction　material.　And　the　mechanical　properties　and　tribological　properties　of　the　composites　were　studied.　The　results　show　that,　with　the　increase　of　rice　husk　powder　content,　the　impact　strength　of　specimen　increased　first　and　then　declined,　however,　the　rockwell　hardness　decreased　continuously.　As　the　amount　of　rice　husk　powder　increased,　the　friction　coefficients　also　increased　first　and　then　decreased.　At　high　temperature,　rice　husk　powder　as　filler　promoted　the　formation　of　the　friction　layer,　stabilized　the　friction　coefficient,　and　improved　the　heat　recession.　In　addition,　it　increased　the　heat　resistance　and　thermal　stability.　When　rice　husk　powder　content　was　15%,　its　comprehensive　performance　is　the　best.　©,　2015,　Science　Press.　All　right　reserved.
