Joining magnesium with reinforced polymer composite fasteners |
摘要 |
A method is disclosed for forming corrosion-resistant joints in a plurality of overlapping thin metal sheet workpieces, at least one of which comprises at least 85% by weight of magnesium sheets. The fastener is a fiber-reinforced polymer rod shaped and sized for insertion into a coaxial opening formed in each sheet and subsequently upset on each end to form a head. The workpiece sheets are deformed to form mechanically-interfering features which cooperatively complement the strength of the fastener, under at least some joint loading patterns. The method may be used for other workpiece and fastener compositions.
