Abstract
A truss type extruded aluminum section is formed of a pair of planar plates and ribs, wherein hollow portions are formed within said section by the ribs and the planar plates. Vibration-damping resin is provided on the inner surfaces of hollow portions, and particularly on the inner surface of the planar plate and on a single surface of the inclined rib. With this arrangement, the vibration energy bending the planar plate and the rib is converted into a heat energy. In the case of manufacturing such truss type extruded aluminum vibration-damping section, for making easy the insertion of the vibration-damping resin in the hollow portion, the vibration-damping resin is stuck on a plastic film to form a long planar body. The plastic film serves as a cover or an adhesive. Moreover, in the case of directly inserting the vibration-damping resin sheet, the vibration-damping resin sheet is subjected to embossing on the adhesive-bonding side for allowing air to escape. Additionally, in the case using an age-hardening type aluminum alloy, the adhesive-bonding for the vibration-damping resin by heating is performed along with the heat treatment for age-hardening.
