Abstract

Изобретение относитс  к способу изготовлени  многослойных конструкций, предназначено дл  изготовлени  панелей, оболочек и др. изделий из композиционного материала с сотовым заполнителем. Цель изобретени  - повышение прочности. Дл  этого сотовый заполнитель формируют из пропитанной св зующим неотвержденной ленты 3, которую располагают торцом к поверхности неотвержденной нижней обшивки 2 в соответствии с заданной геометрической формой  чеек путем прерывистого дискретного перемещени  ленты с шагом, равным длине каждой очередной грани  чейки относительно стержней, которые внедр ют в неотвержденную нижнюю обшивку 2 перпендикул рно ее поверхности и на них насаживают неотвержденную верхнюю обшивку. Затем производ т полимеризацию , причем фиксирующие стержни 4 имеют длину не более высоты конструкции. 4 ил. (Л СThe invention relates to a method for producing multilayer structures, intended for the manufacture of panels, shells and other products made of a composite material with a honeycomb core. The purpose of the invention is to increase the strength. For this purpose, the cellular aggregate is formed from the uncured tape 3 impregnated with a binder, which is positioned face to the surface of the uncured bottom casing 2 in accordance with a given cell geometry by intermittent discrete movement of the tape with a step equal to the length of each regular edge of the cell relative to the rods, which are inserted into the uncured bottom casing 2 is perpendicular to its surface and an uncured upper casing is placed on them. Then polymerization is carried out, with the locking rods 4 having a length not exceeding the height of the structure. 4 il. (Ls

Формула изобретенияClaim 1. Способ изготовления многослойных конструкций с сотовым заполнителем, включающий выкладку на формообразующую поверхность нижней обшивки, укладку на нее сотового заполнителя из пропитанного связующим ленточного материала и выкладку верхней обшивки с последующим отверждением конструкции, отличающийся тем, что, с целью повышения прочности, сотовый заполнитель получают в процессе сборки слоев путем укладки ленточного материала относительно внедренных перпендикулярно в нижнюю обшивку стержней, установленных в местах изменения ее направления согласно форме ячеек.1. A method of manufacturing multilayer structures with honeycomb core, including laying on the forming surface of the lower skin, laying on it a honeycomb core impregnated with a binder material and laying the upper skin with subsequent curing of the structure, characterized in that, in order to increase strength, honeycomb is obtained in the process of assembling the layers by laying tape material relative to the rods inserted perpendicularly into the lower skin, installed at the places where it changes avleniya according to the form of cells. 2. Способ поп. 1,отличающийся тем, что длина стержня выполнена не более высоты многослойной конструкции.2. The method of pop. 1, characterized in that the length of the rod is made no more than the height of the multilayer structure. (pus. ί фиг. 4(pus. ί Fig. 4
