POLYMER WELDING USING FERROMAGNETIC PARTICLES

摘要

An apparatus and method for bonding polymeric materials is disclosed. The apparatus and method both utilize ferromagnetic materials in association wit h the polymeric materials to be bonded together. The polymeric materials, and the ferromagnetic material, are placed within a magnetic field, which causes hysterisis losses in the magnetic field, and thus elevation in the temperatu re of both the ferromagnetic material and the polymeric materials to the point where the polymeric materials melt and fuse together. The ferromagnetic materials only rise in temperature to their Curie temperatures, at which poi nt the hysterisis losses cease, and the polymeric material stops beng heated. Removing the electromagnetic field allows for cooling and fusing. An interfa ce composition may also be placed between the two polymeric materials to be bonded.
