Изобретение относитс к способам изготовлени бескаркасных панелей из композиционных материалов.This invention relates to methods for making frameless panels of composite materials.
По основному авт. св. № 341684 известен способ изготовлени длинномерных бескаркасных панелей, армированных стекловолокном путем намотки на полые эластичные оправки пропитанного св зующим стекловолокна , укладки полученных заготовок в форму, уплотнени их с последующим отверждением св зующего.According to the main author. St. No. 341684, there is known a method for manufacturing long frameless panels reinforced with glass fiber by winding impregnated glass fiber with hollow elastic mandrels, laying the prepared blanks into a mold, compacting them and then curing the binder.
Предлагаемый способ отличаетс от известного тем, что среду в полости эластичных оправок дополнительно нагревают и осуществл ют ее циркул цию, поддержива в полости в процессе уплотнени издели посто нное избыточное давление и температуру, равную температуре отверждени св зующего. Это обеспечивает изготовление бескаркасных панелей с точными геометрическими размерами, равномерными толщинами ребер заполнител и обшивок при равномерном отвержденииThe proposed method differs from the known fact that the medium in the cavity of the elastic mandrels is additionally heated and circulated, maintaining a constant overpressure and temperature in the cavity during the sealing process of the product equal to the binder's curing temperature. This ensures the production of frameless panels with exact geometrical dimensions, uniform thickness of the filler ribs and skins with uniform curing
св зующего во всех точках панели и высоком качестве прессовани .binder at all points of the panel and high quality of pressing.
Сущность способа заключаетс в том, что в процессе отверждени св зующего через эластичные оправки осуществл ют циркул цию подогреваемой до температуры отверждени св зующего среды и обеспечивают избыточное давление внутри эластичных оправок.The essence of the method is that during the curing of the binder through elastic mandrels, the binder medium heated to the curing temperature is circulated and provides excessive pressure inside the elastic mandrels.
