Verfahren zur Fernerhitzung eines Polymeren Werkstoffes auf eine gewählte Temperatur

摘要

Method for remotely heating a polymeric material to a selected temperature in which particulate ferromagnetic material (3) having a Curie temperature corresponding to the selected heating temperature is dispersed throughout the polymeric material to form a composite, and microwave energy is applied to the resulting composite. Preferably, the particulate ferromagnetic material comprises only about 2 percent of the total composite by weight. The polymeric material may be compliant, thermosettable plastic, and the Curie temperature of the particulate ferromagnetic material dispersed therein may advantageously be above the curing temperature of the polymer, such that a beam (13) of microwave energy may be used to remotely join surfaces or construct joints in composite structures.
