Title:
THERMOSETTING PHENOLIC RESIN COMPOSITION OR COMPOUND, OR CARBON COMPOSITE THEREOF
Document Type and Number:
WIPO Patent Application WO/2001/048085
Kind Code:
A1
Abstract:
A thermosetting phenolic resin composition or compound characterized by comprising 10 to 85 wt.% phenolic resin obtained mainly by reacting phenol with formaldehyde and having reactive hydroxymethyl groups and a weight-average molecular weight of 1,000 or higher, 90 to 15 wt.% furfuryl alcohol, and 0 to 17 wt.% hardener; or a carbon composite of the composition or compound. The composition or compound or the composite is effective in improving the strength of an unburned object in producing a carbon-containing refractory or a carbon fiber/carbon composite material. It is effective also in yielding a burned object having an improved carbon yield. Furthermore, it is effective in reducing the amount of gas generation and in lowering gas toxicity.
