When the composite material molded product has, for example, a bent portion, a surface on an inside of the bent portion is a pressed surface. A mold includes a pressing body that is thermally expandable and has an outer surface shape corresponding to a shape of a pressed surface, and a mold main body including a cavity accommodating the laminate and the pressing body inside, the cavity including an inner surface shape corresponding to a shape other than the pressed surface. The cavity is sealed in a state that the pressing body is disposed in the cavity. The laminate is accommodated in a molding space formed between an inner surface of the cavity and an outer surface of the pressing body.

Press assembly having a press tool

A press tool for a press assembly includes an additive manufactured body including a plurality of stacked layers of additive manufacturable material extending between an interior side and an exterior side. The interior side has a part forming surface including a surface profile for forming a part. The exterior side has a plurality of hollow cores defined by longitudinal walls and lateral walls meeting at joints. Press inserts are coupled to the longitudinal walls and the lateral walls at the exterior side. The press inserts are configured to be pressed inward by a pressing load during a pressing operation for forming the part. The press inserts distribute the pressing load along the longitudinal and lateral walls.

MANUFACTURING METHOD FOR FIBER-REINFORCED PLASTIC COMPOSITE

Provided is a method for manufacturing a fiber-reinforced plastic composite containing a fiber-reinforced plastic part having a plate-like portion and a rib protruding from one surface of the plate-like portion, and a metal part, having an average thickness of 0.5-3.0 mm, laminated on part of or all of the plate-like portion of the fiber-reinforced plastic part, comprising: a lamination step for stacking a plurality of incised prepreg layers as a plurality of sheets of base material to form a base laminate, each prepreg layer containing unidirectionally oriented fibers and resin, and a plurality of incisions crossing the fibers, a base material heating step for heating the base laminate, and a molding step for integrating the base laminate and the metal part by pressing them between a rib molding member having a recessed portion for forming a rib and a skin molding member free of such a recessed portion in a pressing device.

PRESSURE PLATE ARRANGEMENT, PRODUCTION ARRANGEMENT, DEVICE AND METHOD FOR PRODUCING A TRANSITION REGION BETWEEN AERODYNAMIC PROFILE ELEMENTS
20200386001 · 2020-12-10 ·

In order to allow or improve a laminar air flow in a transition region between aerodynamic profile elements, a pressure plate arrangement is proposed. The pressure plate arrangement comprises a pressure plate body and at least one cover strip, in particular a sealing strip. The pressure plate body has an outlet region from which free-flowing sealant can exit during pressing. The cover strip already contains cured sealant and presses the free-flowing sealant flat in order to be able to form the transition region.
