ABSTRACT:
A method of making a connecting rod for an internal combustion engine which includes shaping a bundle of unidirectional inorganic fibers, placing the bundle into a shaping container and heating it partially in order to fuse the fibers to each other. The partially fused bundle is positioned in a mold in such a manner to produce an extra gap for a predetermined machining allowance between the bundles and cavities. A molten light metal alloy is squeeze cast into the mold under high pressure, i.e., 500-2000 kg/cm.sup.3, forming a matrix annular layer around the bundle. The rod portion of the obtained connecting rod is machined to remove defects in casting, such as a fatigue crack, a blow-hole or mixing of oxidated substances and takes the shape of a circular or elliptical cross-section.
