METHOD OF PRODUCING COMPOSITION BASED ON POLYCARBONATE AND EPOXY RESIN Russian patent published in 2020 - IPC C08L63/00 E04C2/36 E04C2/20 B32B3/00 B32B5/28 E04B1/76

Abstract RU 2715833 C2

FIELD: construction.

SUBSTANCE: invention relates to production of construction materials and particularly relates to production of a structural cellular panel from polycarbonate honeycomb sheet. When constructing a structural cellular panel, hollows of the cellular polycarbonate sheet are filled with an oil-fill syringe with a mixture of epoxy resin ED-20 and hardener PEPA at ratio of 10:1 with a pitch through one cell. Mixture can additionally contain a filler of granular polypropylene or foamed polystyrene.

EFFECT: invention improves physical and mechanical properties, particularly impact strength and stiffness.
