Abstract
The present invention fills a long-felt need for an improved phenol-furan resin composition used as a chimney liner with reduced combustibility, and for the preparation of pre-impregnated fiber-reinforced composite material and its use. The invention shows a higher tolerance for certain conditions that are damaging to other resin compositions including higher heat tolerance and higher tolerance for flue gases and other compounds.
