Abstract

A method of producing straight channels in aluminum is proposed. Hot extrusion of cylindrical billets containing aluminum powder with resin inserts is examined. First, it is found that aramid inserts successfully act as a space holder, which thin down without breakage during extrusion. The aramid inserts are burned out in the subsequent firing process, and the penetration in the extruded bar is confirmed. Secondary, the influence of different extrusion conditions on the extruded profiles is investigated. The reduction in diameter of the aramid inserts varies in a certain extent, but its average is almost stable under the test conditions. Thirdly, material test of the single aramid fiber is conducted to compare its mechanical property with that of the aluminum matrix. The ductility of the aramid fiber is similar to that of the aluminum powder matrix during hot extrusion.
