Analisis Sifat Fisik Dan Mekanik Akibat Variasi Temperatur Uji Pada Komposit Serat Batang Pohon Pisang Yang Disusun 5 Lapis Dengan Orientasi Serat (-30/60/0/-30/60)

摘要

This study aimed to describe the tensile strength andudbending strength of the composite fibers are arranged banana treesud5 layers with fiber arrangement -30 / 60/0 / -30 / 60 and describeudmacro picture after the tensile test and bending due to changesudtemperature.udThe initial process pelupasan and cutting tree barkudpisang.Proses immersion for 1 month followed pengerokan andudbrushing using a metal plate to exit seratnya.Penjemuranudcool, dry place until the next washing process usinguda chemical solution of 5% potassium permangant per 1 liter of distilled water for 2udjam.penjemuran under the sun to dry resumed processudoven until the moisture content is constant. Composite manufacturing methodsudHand Lay-up, using fiber weight fraction ratio of 30%udand fiber orientation -30 / 60/0 / -30 / 60. Using a tensile testudASTM D 3039 standard and bending tests using standardudASTM D7269 with a temperature variation of 29 0C and temperature testud350C, 450C and 55 0C, and describes the tensile strength and bendingudas well as macro image of composite polyester fiber banana trees dueudchanges in temperature.udThe test results concluded that the higher the temperature testudthe tensile strength is getting weaker or down, this proved to be the tensile strengthuddecreased from 26.4 N / mm2 to 20.3 N / mm2 and theudtemperaruji higher bending test, the test voltage valuesudthe higher the bending is evident that the increase in value of the voltageuddari0,278 N / mm2 to 7.08 N / mm2 .At visible results macro photoudfault structure has the properties of clay composite specimens.
