Mechanical Properties of Oil Palm Trunk By Reactive Compregnation Methode with Dammar Resin
MetadataShow full item record
The research about compregnation reactive of oil palm trunk (OPT) has been done. The aim of this research is to achievement the quality of reactive compregnation OPT with the dammar resin. This research has been made in several steps such as preparation of the sample of OPT, resin preparation, the process of compregnation of OPT and characterization of OPT by using mechanical test, FTIR, SEM and TGA. Compregnation of OPT with dammar resin was done by using various concentration. Dammar resin with different concentrate has been diluted in methanol and was compregnation in OPT pore which shape 15x2x2 cm3 whichlaid in modified compregrator which has -0.2atm pressure for about 5 minutes. According to mechanical test of OPT, it has resulted that the mechanical properties optimum of OPT for the 20% dammar resin the value modulus of elasticity (MOE) 195,829 MPa. From the test of TGA is seen that the nature of OPT thermal is achieved. It can be seen from degradation of palm oil trunk from 2000C to 2500C with 20% dammar resin. From the analysist of SEM, morphology of OPT after compregnation become closer and solid because the pore of OPT has been fulfill with dammar resin. From the mechanical test and thermal gravimetry analisys, it has been found that OPT from the result of compregnation has higher mechanical nature and thermal stability compare to OPT before compregnation.
