DEVICE FOR MAKING LONG-LENGTH PANEL WITH STIFFNESS RIBS OF POLYMER COMPOSITE Russian patent published in 2013 - IPC B29C39/10 B29C39/34 B29C43/42 

FIELD: process engineering.

SUBSTANCE: invention relates to fabrication of panels from polymer composite by forced impregnation of panel preform and can be used in aerospace engineering, ship building, automotive industry, etc. Device comprises bearing plate and forming elements. The latter comprises central bearing element mounted at bearing plate, peripheral elements and mid elements arranged there between in number corresponding to that of panel preform cells. Undercuts are made at sides of mid elements. Central and mid elements represent long-length sections and have outside horizontal base and vertical sidewalls to make "П"-like outer forming surface in cross-section mating the panel preform cell surface. Peripheral elements are formed by long-length V-channel. They comprise mutually perpendicular flat horizontal base and sidewall to press mid elements to central bearing element. All forming elements face said bearing plate by their bases and tightly jointed therewith via sealing braids. They are configured in one line to adjoin each other by sidewall outer surfaces to form a closed unit with panel base and preform ribs moulding cavities. Besides, it can comprise at least one above described unit. Note here that sidewalls of every unit can be attached to adjacent unit end walls.

EFFECT: lower eight, fast assembly and accelerated production of long-length panels.
