ABSTRACT:
A composite material5in which a dispersing material7is dispersed in a matrix6is provided. The composite material5is producible by steps offilling said mixed material in a space forming region to be defined by at least two container elements when said at least two container elements are integrated into one body, andthen infiltrating said aluminum (Al) being molten due to heat generated by said self-combustion reaction into pores inside said mixed material through at least one hole formed in an upper part of a reaction container formed by combining said at least two container elements in which said mixed material is filled in said space forming region in a state being fixed to a predetermined shape, thereby an aluminide intermetallic compound is formed by self-combustion reaction between said metal powder and said aluminum (Al), and a dispersing material is dispersed into said matrix.
