Abstract

The porous composite material is a composile of two differeni or more types of materials which still carry the properties of the prior material into nevv material having better material properties and the material structure having pores generated from the space holder material. This study aims to analyze the effect of material space holder variation on physical properties and mechanical properties of porous composites. The composite materials of porous composites consist of Aluminum powder (matrix), Fiber glass (reinforcement), and variations of material space holder consisting of rubber, purple sweet potato and green beans. The method used in the fabrication is the compaction and sintering method, with compression pressure of 1500 psi (100 kg /cm2) and sintering temperature 500°C with a holding time of 2 hours. The test parameters were performed on the porous composite material to know the properties and characteristics of the porous composite material, the test included the testing of the Chemical composition of aluminum powder, the TGA test of the powder of the space holder, then the density test, compressive strength test, XRD test and SEM observation third variation of porous composite materials. From the results of TGA testing conducted on the three material space holder, the occunrence of material decomposition on the powder space holder when the temperature above 200°C which resulted in the decrease in weight due to the influence of temperature rise. The result of density test showed porous composite of green beans space holder material had the highest porosity value with the porosity value of 27.91% and the lowest porosity value was found in the porous composite material of rubber space holder with the value of 24.91%, for compressive strength test of porous composite material space holder rubber has the best compressive strength value with the value 23,37 MPa and the lowest compressive strength value is found in the porous composite material of green beans space holder with value 16,87 MPa. For XRD test results there are two peak list data showing the other phase in porous composite material of the rubber space holder, whereas in the porous composite sample of sweet potato space holder and green beans xvu XVI u space holder there are no pcak list data showing the formation of another phase. For the SEM observation results the three space holder materials proved to produce pores in the composite material, the pores produced in the composite material did not have a uniform si2e, with a pore size range of 5.97 pm to 21.19 pm.
