METHOD FOR MANUFACTURING FIBER-REINFORCED POLYMER MOLDED PRODUCT AND A DEVICE FOR ITS MANUFACTURE Russian patent published in 2021 - IPC B29C45/04 

FIELD: product reinforcement.

SUBSTANCE: invention relates to methods and devices for manufacturing fiber-reinforced polymer molded products, for example, a high-pressure tank. The method includes forming a preform, impregnating the fiber layer of the preform with polymer and curing the polymer, placing the preform between the first mold and the second mold of the press tool so as to create the first gap between the first mold and the preform and the second gap between the second mold and the preform, pouring the polymer into the mold through the polymer inlet hole in the direction of the second gap, moving at least part of the first mold facing the preform, from the preform to create a third gap between at least part of the first mold and the preform to move the polymer inside the press tool, that was poured in the direction of the second gap into the gap between the first mold and the preform, and the convergence of the second mold and at least part of the first mold with the preform to fill the press tool with polymer under pressure.

EFFECT: invention provides the prevention of deformation of the preform.
