Abstract | FIELD: composite materials.SUBSTANCE: invention relates to a method of hardening carbon fiber modified with active metal particles intended for production of composite materials, which in their turn are in demand in many spheres of consumption and industries. Technical result is achieved by a method involving modification with active metal particles, wherein the carbon fibers are coated with a layer of aluminum hydroxide with thickness of 1 to 2 nm, then the hydroxide is dehydrated, then the fiber is impregnated with a solution of a metal salt, then the obtained salt particles are reduced to a metal state.EFFECT: technical result consists in improvement of binding strength of carbon fiber and polymer matrix in composite materials.5 cl, 5 dwg, 8 ex
Изобретение относится к способу упрочнения углеродного волокна, модифицированного активными частицами металла, предназначенного для получения композиционных материалов, которые в свою очередь востребованы во многих сферах потребления и отраслях производства. Технический результат заключается в повышении прочности связывания углеродного волокна и полимерной матрицы в композиционных материалах. Технический результат достигается способом, включающим в себя модифицирование активными частицами металла, при этом углеродные волокна покрывают слоем гидроксида алюминия толщиной от 1 до 2 нм, затем обезвоживают гидроксид, затем пропитывают волокно раствором соли металла, затем восстанавливают полученные частицы соли до металлического состояния. 4 з.п. ф-лы, 5 ил., 8 пр. |
