FASERVERSTÄRKTER, MIT AROMATISCHEM AMINVERNETZER VERNETZTER PHTHALONITRILVERBUNDWERKSTOFF MIT NIEDRIGER REAKTIVITÄT |
摘要 |
A fiber-reinforced phthalonitrile composite is made by impregnating or coating a fibrous material with a phthalonitrile prepolymer mixture containing a phthalonitrile monomer and an aromatic amine curing agent that is thermally stable and nonvolatile at a temperature up to about 375 DEG C., and that contains at least one electron withdrawing substituent effective to reduce the reactivity of the aromatic amine curing agent with the phthalonitrile monomer. |
