Open the CIPO recordAbstract From the Canadian patent
The present invention provides a, metal/polymer composite comprising a polymeric substrate and a sintered mat of randomly-oriented metal fibers embedded therein, the fibers having a substantially circular cross-section and a diameter of about 10 to 200 µm. The polymeric substrate is typically a thin, flexible sheet-like material having a pair of planar surfaces. The polymeric substrate is preferably thermoformable. If thermoformability is desired the metal will have a melting point of less than the thermoforming temperature of the polymeric substrate. The thermoformable metal/polymer composite of the present invention may be stretched to at least 20%, and often can be stretched at least …

Why it's free to use
- Filed January 4, 1990 and granted September 18, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 4, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 4, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
