This study aimed to describe the tensile strength andbending strength of the composite fibers are arranged banana trees5 layers with fiber arrangement -30 / 60/0 / -30 / 60 and describemacro picture after the tensile test and bending due to changestemperature.The initial process pelupasan and cutting tree barkpisang.Proses immersion for 1 month followed pengerokan andbrushing using a metal plate to exit seratnya.Penjemurancool, dry place until the next washing process usinga chemical solution of 5% potassium permangant per 1 liter of distilled water for 2jam.penjemuran under the sun to dry resumed processoven until the moisture content is constant. Composite manufacturing methodsHand Lay-up, using fiber weight fraction ratio of 30%and fiber orientation -30 / 60/0 / -30 / 60. Using a tensile testASTM D 3039 standard and bending tests using standardASTM D7269 with a temperature variation of 29 0C and temperature test350C, 450C and 55 0C, and describes the tensile strength and bendingas well as macro image of composite polyester fiber banana trees duechanges in temperature.The test results concluded that the higher the temperature testthe tensile strength is getting weaker or down, this proved to be the tensile strengthdecreased from 26.4 N / mm2 to 20.3 N / mm2 and thetemperaruji higher bending test, the test voltage valuesthe higher the bending is evident that the increase in value of the voltagedari0,278 N / mm2 to 7.08 N / mm2 .At visible results macro photofault structure has the properties of clay composite specimens.
