GREASING COMPOSITION, CARBON FIBRES AND THEIR APPLICATION TO THE REINFORCEMENT OF POLYMER MATRICES

摘要

the composition contains at least one selected from acid sizing agent polyamiques oligomers and the products resulting from the total or partial imidisation such acids.in the polycondensation of an aromatic ring linked pyromellitic polynuclear aromatic diamine with a polynuclear nuclei with closed chain linked only by a carboxylic diacid anhydride group or its form.only by a primary amine group or a group derived from the reaction of a neutral primary amine group on the terminal monofunctional anhydride or acid anhydride to the reaction of monofunctional or on the groupememnt terminal primary amine.the carbon fibers ensimu00e9es using this composition can be used for the reinforcement of polymer matrices to form composite materials, particularly with improved coating adhesion between fibers and matrix, particularly with polyim matrices ides.
