Open the CIPO recordAbstract From the Canadian patent
In a process that is particularly suitable for producing pipes or hoses the, reinforcing material and the matrix material are no longer produced separately but together in a woven, knitted, braided or non-woven fabric. The matrix material is selected so that its melting temperature is lower than the melting or decomposition temperature of the reinforcing material. The end product is obtained by pultruding the fabricated material, generally designated as textile fabrics at a temperature, above the melting temperature of the matrix material and below the melting or decomposition temperature of the reinforcing material. The product is then cooled to stabilise its final shape.

Why it's free to use
- Filed December 2, 1994 and granted January 30, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 2, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 2, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
