HERDEDE FIBERKOMPOSITTER, SAMT FREMGANGSMAATE FOR FREMSTILLING AV EN SLIK. |
摘要 |
<p>This invention is directed to cured fibrous composites prepared from the resinous reaction products of hydroxy aromatic mono-aldehydes and methylated pyridines or methylated pyrazines. This invention is also directed to thermosettable prepolymers prepared from hydroxy mono-aldehydes and methylated pyrazines or pyridines. …<??>The total number of methyl groups in the pyridine or pyrazine ranges from 2 to 4. The composites are prepared from conventional fibers such as graphite fibers, glass fibers, aramid fibers, or asbestos fibers.</p> |
