Abstract
Composite materials consisting of porous aluminum and resin are expected to meet the current demand for the weight reduction of parts. The objective of this study is to introduce friction welding for joining porous aluminum and a polycarbonate plate. The advantages of friction welding are that it is a simple process and the joining surface is locally and directly heated by the friction heat generated between the porous aluminum and the polycarbonate plate. We showed that joining of porous aluminum and a polycarbonate plate can be achieved by friction welding via the anchor effect without the collapse of pores. The observed joining strength was similar to the strength of the porous aluminum itself.
