Temperature-Controlled Induction Heating Of Polymeric Materials
US Patent:
6939477, Sep 6, 2005
Filed:
May 1, 2001
Appl. No.:
09/847055

Assignee:
Ashland, Inc. - Columbus OH
International Classification:
H01F001/113, H01F001/37
US Classification:
252 6254, 524435
Abstract:
The present invention provides new polymer induction bonding technology. Induction heating technologies are utilized to weld, forge, bond or set polymer materials. The invention provides controlled-temperature induction heating of polymeric materials by mixing ferromagnetic particles in the polymer to be heated. Temperature control is obtained by selecting ferromagnetic particles with a specific Curie temperature. The ferromagnetic particles will heat up in an induction field, through hysteresis losses, until they reach their Curie temperature. At that point, heat generation through hysteresis loss ceases. This invention is applicable to bonding thermoplastic materials, wherein only the area to be heated has ferromagnetic particles in it; bonding of thermoset composites, which have been processed with a layer of thermoplastic material on one side; curing of thermoset adhesives or composite resins; or consolidating thermoplastic composites.

US Patent:
2004012, Jul 8, 2004
Filed:
Feb 23, 2004
Appl. No.:
10/432278
Inventors:
Philip Stark - Concord MA, US
International Classification:
H01B001/00
US Classification:
252/500000
Abstract:
The invention relates to an agent for heating materials comprising (a) at least one plurality of electrically non-conductive susceptors and (b) at least one plurality of electrically conductive susceptors. Preferably the electrically non-conductive susceptors comprise micron-sized ferrimagnetic particles and the electrically conductive particles comprise ferromagnetic particles or intrinsically conductive polymer particles.
