Abstract
A process for mechanically bonding a sheet of rubber to a sheet of another, e.g. a reinforcing, material, and a composite article made by the process. A molded sheet of rubber having integral upstanding posts is assembled with the sheet of the other material in such a manner that the posts extend through openings in the sheet of the other material. The distal ends of the rubber posts are then reformed (preferably by heating) to shape or form the rubber posts into rivets which mechanically lock the rubber sheet and the sheet of other material together and provide good shear resistance. According to another embodiment of the present invention, the reinforcement material is a high melting temperature plastic which has an upstanding post and the molded rubber sheet and has openings therein. The plastic posts are reformed as with a laser to bond the plastic sheet to the rubber sheet.
