| Abstract | : | In general, this study was aimed to test the porosity of composite materials. The test was using X-ray micro-computed tomography (micro-CT) system developed at the Department of Physics, Universitas Gadjah Mada, Indonesia. Testing was done for three composite materials comprised by ultra fine amorphous silica (UFAS) from rice husk. Samples were made in three variations of compositions M1, M2, M3 namely a) UFAS1 plus rice husk powder, resin and catalyst, b) UFAS2 plus rice husk powder, resins, and catalysts, and c) powder UFAS3 plus rice husk, resins, and catalysts. Rice husks powder has an average fineness of 150 meshes. The testing procedure included preparation, process of scanning, data processing, and data analysis. The results showed that the linier attenuation coefficient of materials M1, M2, and M3 were (9.2 ± 0.5) x 10-3 cm-1, (9.7 ± 0.1) x 10-3 cm-1, and (10.0 ± 0.1) x 10-3 cm-1 respectively. The porosity of materials M1, M2, and M3 were 13.74%, 11.31%, and 7.22% respectively |
