To　improve　the　high-temperature　tribological　performance　of　the　polymer　composite,　an　oil-containing　laminated　composite　was　prepared　bionically　by　adding　the　poly-α-olefin　(PAO)　oil　into　the　polymer,　and　the　oil-containing　polymer　was　filled　into　the　laminated　grooved　surface.　The　tribological　performance　of　the　composite　was　investigated　on　a　pin-on-disc　tribometer　under　high　temperature　condition.　It　was　found　that　with　the　increase　of　the　test　temperature,　the　friction　factor　of　the　laminated　composite　without　oil　was　increased　and　lubrication　failure　occurred　at　150℃.　For　the　oil-containing　composite,　the　average　friction　factor　was　as　low　as　below　0.1　in　the　temperature　range　of　25-150℃,　but　increased　to　0.18　as　temperature　rose　to　200℃.　The　analysis　of　wear　scars　showed　that:　(i)　for　the　laminated　composite　without　oil,　the　wear　type　of　steel　surface　was　severe　abrasive　wear,　while　the　polymer　surface　was　erosion　and　wear;　and　(ii)　for　the　oil-containing　laminated　composite,　the　steel　surface　presented　minor　scratches　and　the　polymer　surface　showed　plastic　flow.　The　lubrication　mechanism　of　the　oil-containing　laminated　composite　can　be　deduced　as　follows:　polymer　porous　structure　can　stockpile　the　oil　in　the　base　material,　the　heat　drives　oil　moving　to　the　frictional　surface　and　hence　forming　a　stable　lubricating　oil,　thus　the　lubrication　life　of　the　oil-containing　laminated　composite　can　be　improved　under　high-temperature　conditions.　©　2017,　Editorial　Office　of　Journal　of　Xi＇an　Jiaotong　University.　All　right　reserved.
