FIELD: manufacture of sheet materials (semi- finished products) for molding composite articles, including multi-layer sandwich-type structures on base of thermosetting binders and hollow glass micro-spheres. SUBSTANCE: composites are promising for manufacture of articles at high specific elasticity and strength characteristics. Proposed method includes preparation of compound from these components in form of granules followed by rolling them by means of rolls or in belt-type press to required thickness; belt is first molded from compound granules in extruder provided with slotted head. The highest efficiency of use of material is attained at 60- to 70-% by volume of content of hollow glass micro-spheres. EFFECT: enhanced efficiency. 2 dwg
