Abstract
A composite material structure includes a first metal member and a second metal member bonding to the first metal member. A bonding surface is formed therebetween. A first hole is through the first metal member. A circular bonding line is formed at a junction of a wall of the first hole and the bonding surface. A sleeve protrudes from the second metal member into the first hole, and covers the bonding line. A groove indents from the first metal member. The groove has a bottom surface located in the same plane with a top surface of the sleeve. A processing method of the composite material structure is also provided. The sleeve covers the bonding line between the first metal member and the second metal member, which allows the composite material structure to provide an improved sealing performance.
