Description
Изобретение относитс к способам изготовлени трехслойных конструкций с сотовым заполнителем, предназначенных, в частности, дл использовани в крыль х и фюзел жах летательных аппаратов.The invention relates to methods for producing honeycomb sandwich panels, in particular for use in aircraft wing and fuselage.
Известный способ изготовлени трехслойных конструкций с сотовым заполнителем, основанный на соединении между собой гофрированных полос с последующей их укладкой между несущими обшивками, не обеспечивает необходимой жесткости и прочности трехслойной конструкции.The known method of manufacturing three-layer structures with honeycomb filler, based on the interconnection of corrugated strips with their subsequent laying between the bearing skins, does not provide the necessary rigidity and strength of the three-layer structure.
Предложенный способ не имеет указанных недостатков.The proposed method does not have these disadvantages.
Сущность изобретени заключаетс в том, что скрепленные между собой гофрированные полосы заполнител оплетают по спирали покрытой соединительным составом арматурой и наматывают плотно прилегающими витками на одну из несущих обшивок.The essence of the invention is that the corrugated filler strips fastened together between themselves twist spirally with reinforcement coated with a connecting compound and wind tightly wound coils onto one of the bearing casings.
Предложенный способ изготовлени трехслойных ко«стру кций новыщает их н :есткость и прочность.The proposed method of manufacturing three-layer structures enhances their n: rigor and strength.
На чертеже изображена схема изготовлени трехслойной цилиндрической конструкции с сотовым заполнителем.The drawing shows a scheme for manufacturing a three-layer cylindrical structure with a honeycomb core.
Полосы /-5 алюминиевой фольги сматывают с рулонов 4-6 и подают в гофрирующие механизмы 7-9 (пары гофрирующих роликов ). Шаг гофров всех полос одинаковый, аStrips of / -5 aluminum foil are wound off rolls 4-6 and fed into crimping mechanisms 7-9 (a pair of corrugating rollers). The pitch of the corrugations of all bands is the same, and
высота гофров полос / и 5 меньше, чем полосы 2. Затем все полосы подают на контактные ролики 10 сварочного аппарата, где их соеднн ют сваркой по полкам гофров. Соедипенные между собой полосы /-3 подают в оплеточный механизм 11, с. помощью которого их оплетают по спирали стеклонитью 12, пропитанной эпоксидным соединительным составом .the height of the corrugations of the strips / and 5 is less than that of the strips 2. Then all the strips are fed to the contact rollers 10 of the welding apparatus, where they are joined by welding along the flanges of the corrugations. The interconnected bands / -3 are fed to the braiding mechanism 11, p. by means of which they are braided in a spiral by glass fiber 12 impregnated with epoxy bonding compound.
На технологическую оправку 13 наматывают внутренний несущий слой стеклоарматуры 14, пропитанной эноксидным св зующим. Поверх сло 14 наматывают занолннтель из плотно прилегающих друг к другу витков оплетенных полос /-3.An internal carrier layer of glass fittings 14 impregnated with an enoxide binder is wound onto the processing mandrel 13. On top of layer 14, a zonolntel is wound from tightly intertwined turns of braided strips / -3.
Поверх заполнител наматывают наружный несущий слой 15 из пропитанной эпоксидным св зующим стеклоарматуры.An outer support layer 15 is made of glass reinforcement impregnated with epoxy binder on top of the filler.
Затем св зующее отверждают и в процессе термообработки происходит соединение полос /-3 заполнител между собой и с несущими общивками 14 и 15.Then, the binder is cured and, during the heat treatment process, the bands of the / -3 aggregate are joined to each other and to the supporting materials 14 and 15.
