摘要：Advantage of composite material is to take the outstanding mechanical and functional properties of fibers and powders. However, it is not easy to disperse fine particles homogeneously in metallic matrix. 3-dimentional penetration casting (3DPC) method enables to disperse particles in the matrix homogeneously without segregation. The present study puts its focus on WO3 particle. Several reports are available about photocatalytic property of WO3 in the visible ray region. Photocatalytic is one of the most promising matter that can be used for resolving environment pollution because photocatalytic cause the oxidation reaction that change carbon contained in organic compound (for example acetaldehyde, toluene) into CO2 by light. The aim of this work is to establish the fabrication method using 3DPC, to evaluate the mechanical, photocatalytic properties, and to observe the microstructure using scanning electron microscopy (SEM), transmission electron microscopy (TEM).
