To develop a method of producing straight channels in metal bodies by hot extrusion of billets containing metallic powder with resin inserts, the influence of extrusion conditions on the extruded profiles is examined for the combination of aramid fiber and aluminum powder. The reduction in diameter of the aramid inserts varies in a certain extent, but its average is almost stable under the test conditions. Material tests of the single aramid fiber are also conducted to compare its mechanical properties with those of the aluminum matrix. The strength level and the ductility of the aramid fiber are similar to those of the aluminum powder matrix during hot extrusion.
