Abstract
A polymer composition with a polymer matrix material and magnetic particles. The composition is selectively electro-magnetically heatable by an electrical induction energy frequency that is pulse width modulated through variable time cycles to provide controlled heating.
Claims8
A method for controlled temperature bonding with a polymer composition comprising magnetic particles dispersed in a polymer matrix material, the method comprising the steps of:
- generating electromagnetic induction energy having an electromagnetic induction energy frequency selected from the range of 80 kHz to 30 MHz;
- pulse width modulating the electromagnetic induction energy to generate a first pulse width modulated electromagnetic energy having a pulse width modulation frequency and a first duty cycle selected from a plurality of duty cycles;
- heating the polymer composition with the first pulse width modulated electromagnetic induction energy for a first heating interval;
- pulse width modulating the electromagnetic induction energy to generate a second pulse width modulated electromagnetic induction energy having the pulse width modulation frequency and a second duty cycle selected from the plurality of duty cycles;
- and
- heating the polymer composition with the second pulse width modulated electromagnetic induction energy for a second heating interval.
