Claims (1)

Изготавливают предварительно отформованные заготовки для различных частей единой детали из композиционного материала и соединяют друг с другом в неуплотненном состоянии или состоянии частичного уплотнения при помощи связи между соответствующими прилегающими друг к другу поверхностями заготовок 13, 15, 36 посредством ворсинок или волоконных иголочек 17, 19, которые выступают перпендикулярно к поверхности заготовки 13, 15 и за которые зацепляется поверхность другой заготовки 36. Затем соединенные таким образом заготовки подвергаются совместному уплотнению. Ворсинки или волоконные иголочки образованы на поверхности волокнистой заготовки концами волокон этой заготовки, смещенными в результате ее пробивания иглами. Предлагаемый способ подходит в частности для изготовления панелей типа "сэндвич" из конструкционных термостойких композиционных материалов, причем такая панель состоит из двух жестких слоев обшивки, между которыми располагается заполнитель или сердцевина, из перегородок, перпендикулярных упомянутым выше слоям обшивки.

Preformed blanks are made for different parts of a single piece of composite material and are connected to each other in an unconsolidated state or in a state of partial compaction using the connection between the corresponding adjacent surfaces of the blanks 13, 15, 36 by means of fibers or protrude perpendicular to the surface of the workpiece 13, 15 and for which the surface of the other workpiece 36 engages. Then, the workpieces thus joined are subjected to joint th seal. The villi or fiber needles are formed on the surface of a fiber preform by the ends of the fibers of this preform, which are displaced as a result of punching it with needles. The proposed method is suitable in particular for the manufacture of panels of the type "sandwich" of structural heat-resistant composite materials, and this panel consists of two rigid plating layers, between which there is a core or core of partitions perpendicular to the plating layers mentioned above.
