Rapid Electromagnetic Induction Bonding of Composites, Plastics, & Metals

Abstract

ABSTRACTA rapid electromagnetic induction bonding system has been developed that joins composites, plastics, metals, and combinations of these materials. The equipment is self-contained, low power (100–400 watts) and portable. Gangs of bonders have been used as a seem welder to rapidly join plastic reinforced composite and sheet metal. Structures can be bonded in a factory or in the field. Bonding times for laboratory specimens have been cut by a factor of 10 to 100 times compared to standard press or autoclave bonding. This type of equipment allows for applying heat directly to the bond lines and/or the adherends without heating the entire structure, supports, and fixtures of a bonding assembly.The bonder's portability and low power requirements allow for its use on site in any type of climate with power supplied by a variety of portable sources.
