Изобретение относится к изготовлению композиционных структур, содержащих полые участки и каналы. При изготовлении используют сердечники из металлического сплава, на которые наносят термоотверждаемый препрег. Сердечники размещают на специальной оправке. Оправка и сердечники выполнены из металлических сплавов с различным коэффициентом термического расширения, причем коэффициент термического расширения сердечника превышает коэффициент термического расширения оправки.The invention relates to the manufacture of composite structures containing hollow sections and channels. In the manufacture of used metal alloy cores, which cause thermoset prepreg. The cores are placed on a special mandrel. The mandrel and cores are made of metal alloys with different thermal expansion coefficients, and the thermal expansion coefficient of the core exceeds the thermal expansion coefficient of the mandrel.
