Abstract (en)
[origin: WO9210536A1] This application claims a method for using a dope solution that contains polybenzoxazole or polybenzothiazole polymer or copolymer. Fibers are prepregged with the dope, and the prepreg is be contacted with water or another coagulant to coagulate the polymer and form a matrix composite.
Abstract (fr)
L'invention se rapporte à un procédé utilisant une solution de dopage contenant un polymère ou copolymère de polybenzoxazole ou polybenzothiazole. On préimprègne les fibres avec la solution de dopage et on les met en contact avec de l'eau ou un autre coagulant afin de coaguler le polymère et former une matrice composite.
