Abstract

The purpose of this study was to determine the strength of the composite shaft bermatrik polyester fiber trunk hibiscus against torsion testing and observing the macro image torsional fracture after testing. The process of taking fiber soaking in water for 1 month and then done taking the fiber. Drying of the fibers was carried out at room temperature for 1 day. Furthermore alkalization process with potassium permangate (KMnO4) 2% per 1 liter of aquadest in 2 hours immersion time. The drying was carried out at room temperature and continued in the oven at 35 ° C for 1 hour for 10% moisture content. Molding method (molding) is used to create a composite with the fiber direction 20 / -20, 40 / -40 and 60 / -60 In a torsional test, this test is used to describe the torsional strength and observing the macro image composite shaft fracture hibiscus polyester fiber trunk. Test results can be concluded the highest torsion strength phenomenon at orientation of angle of test 60 0 that is torsional strength 8,979 kg / mm2. In macro structures fracture composite specimens that have pulled out long fiber due to the power matrix decreased. Keywords: Fiber Stem Hisbiscus Tiliaceus , Polyester Resin, Composite Shaft
