Open the CIPO recordAbstract From the Canadian patent
Improved composite structure comprises threads (1) distributed within disperse matrix. The structure has increased strength by virtue of distance between the points of support of the thread span, which is deliberately selected to be less than the distance corresponding to the critical lengths corresponding to buckling. The structure is suitable for various articles of manufacture requiring improved strength-to-weight or rigidity-to-weight ratio in various directions.

Why it's free to use
- Filed January 23, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 23, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 23, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
