Claims (1)

Способ изготовления герметичных тонкостенных стеклопластиковых труб из препрега, включающий намотку препрега на металлическую оправку, нагрев препрега, термообработку намотанной стеклопластиковой трубы, отличающийся тем, что предварительно нагревают металлическую оправку до температуры, обеспечивающей эластичное состояние связующего, содержание связующего берут в соотношении 38-42%, после чего производят намотку препрега, нагревающегося от оправки в процессе намотки, при натяжении, обеспечивающем продавливание связующего сквозь каждый наматываемый слой стеклоткани, вследствие чего происходит удаление воздуха из межнитяного пространства стеклоткани, затем после намотки стеклопластиковой трубы до заданной толщины излишки выдавленного на поверхность трубы раскатывают с помощью холодного формующего ролика по всей поверхности трубы, создавая смоляную пленку, после чего стеклопластиковую трубу подвергают термообработке с вращением оправки, а после отверждения смоляной пленки на поверхности трубы последнюю снимают с оправки.A method of manufacturing a sealed thin-walled fiberglass pipe from a prepreg, including winding the prepreg on a metal mandrel, heating the prepreg, heat treatment of the wound fiberglass pipe, characterized in that the metal mandrel is preheated to a temperature that provides an elastic state of the binder, the content of the binder is taken in the ratio of 38-42%, after which the prepreg is wound, heated from the mandrel during the winding process, under tension, ensuring the binder is pressed through the first layer of fiberglass wound, as a result of which air is removed from the interfacial space of the fiberglass, then after winding the fiberglass pipe to a predetermined thickness, the excess extruded onto the pipe surface is rolled with a cold forming roller over the entire pipe surface, creating a resin film, after which the fiberglass pipe is heat treated with by rotating the mandrel, and after curing the resin film on the surface of the pipe, the latter is removed from the mandrel.
