Abstract. The article analyzes practical experience in creating three-layer structures from composite materials with various types of space fillers. The main technological methods for producing such structures from composite materials are considered, their main features, advantages and drawbacks are analyzed, and ways to improve methods for producing this kind of products from composite materials within the framework of these technologies are shown. It is noted that these technologies can be used to produce various kinds of engineering products with high mass efficiency from fiber-reinforced composite materials operating under conditions of high mechanical and thermal loads.

Keywords: three-layer structures, space filler, composite materials, reinforcing fibers, polymer matrices, composite material molding technologies
