METHOD OF MAKING ARTICLES FROM POLYMER COMPOSITE MATERIALS WITH HIGH DEFORMATION PROPERTIES Russian patent published in 2019 - IPC B32B5/00 B32B37/00 

FIELD: composite materials.

SUBSTANCE: invention relates to structural polymer composite materials based on adhesive prepregs with fibrous filler and can be used in machine building, aircraft building, shipbuilding in production of three-dimensional articles. Method of making articles from polymer composite materials involves depositing on the surface of equipment a separating composition (gelcoat) in layers in accordance with a given reinforcement diagram, laying cut out layers of adhesive prepreg, applying on each layer of adhesive prepreg high-viscosity anaerobic polymer material with minimum indent from the edge of the mold equal to 20–22 mm in a pointwise manner according to a predetermined pattern, laying a closing layer of adhesive prepreg, laying sacrificial layer, installing a vacuum tube, coating of assembly with vacuum film, packing of sealing tape along edge of mold and curing under vacuum for 2–24 hours at temperature of 20–60 °C.

EFFECT: invention provides high deformation properties of articles from polymer composite materials: elasticity and plasticity.
