A method for manufacturing a cellulose product, comprising the steps: dry forming a cellulose blank in a dry forming unit; arranging the cellulose blank in a forming mould; heating the cellulose blank to a forming temperature in the range of 100° C. to 200° C.; and pressing the cellulose blank in the forming mould with a forming pressure of at least 1 MPa.

A method of removing a vacuum bag from a composite mold. Removable strips are placed around the perimeter of the component parts and across the parts to create natural break points in the consumable materials used during manufacture of a composite product, e.g. wind turbine blade. The vacuum bag, and other consumable layers, are placed over the removable strip such that when the strips are pulled, the strip tears, in a controlled and complete manner, through each layer of consumables. This eliminates the need to use a knife/scissor to remove the finished product, thereby avoiding risk of injury.

A method for molding a laminated body includes laminating a reinforced fiber base material on a molding surface of a molding jig to form a laminated body; attaching a pulling jig to a third lamination portion of the laminated body; forming a protrusive curvature part and a recessed curvature part in the laminated body by curving the laminated body along a protrusive curvature surface and a recessed curvature surface formed on the molding surface while pulling the end of the laminated body with the pulling jig; and densifying the laminated body by heating the curved laminated body while pressurizing the same. The reinforced fiber base material is laminated so that at least a part of a gap between layers of the reinforced fiber base material becomes a non-adhered state in a portion from the protrusive curvature part to the third lamination portion formed in the laminated body.

A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a multi-material striking face portion that is made out of a backing layer having a frontal pocket, made out of titanium, and an insert, made out of a composite material, adapted to be inserted into the frontal pocket. The frontal pocket and the insert could have complementary dovetail shaped undercut features to create a mechanical bond between these two components.

According to one implementation, a composite material structure includes a corrugated stringer and a panel. The corrugated stringer has a corrugated structure including portions each having hat-shaped cross section. The corrugated stringer is made of a composite material. The panel is integrated with the corrugated stringer. The panel is made of a composite material. Further, according to one implementation, a manufacturing method of a composite material structure includes: setting a textile on a laminated body of prepregs; and producing the composite material structure by covering the laminated body with a bagging film, forming a vacuum state in a space covered with the bagging film, impregnating the textile with the resin, and thermal curing of the laminated body of the prepregs. The laminated body is a panel before curing. The textile has a structure corresponding to a corrugated stringer.

A curing mold for manufacturing a turbomachine part made of composite material from a preform produced by draping pre-impregnated materials includes: a first body and a second body designed to be attached to each other and jointly defining a fixed air gap for receiving the preform and itself including a molding part of complementary shape with the part to be manufactured and intended to receive a portion to be molded of the preform, and at least one additional part located in a peripheral space of the air gap and intended to receive an additional portion forming an edge of the preform; a heating member designed to heat the preform in the air gap to a first temperature; at least one inflatable bladder housed in the first or second body, facing an additional part of the air gap; a member for injecting a pressurized fluid inside the bladder(s).

The present disclosure includes a mold base set, a forming mold core, a rubber pad or a rubber bladder, and a lateral pressure mechanism, wherein the mold base set includes a first mold base and a second mold base, and the second mold base has a mounting part; the forming mold core is arranged on the first mold base; the rubber pad is arranged on the mounting part, and the base surface and side wall surface of the sheet are molded during mold assembly of the mold base set; and the lateral pressure mechanism includes a slope fixed block fixed to the first mold base and a slope slide block set arranged on the second mold base.

A method of fabricating a composite structure is presented. The method comprises laying up a plurality of composite plies over a layup mandrel; positioning a first caul plate and a second caul plate over the plurality of composite plies, leaving composite material exposed; removing at least part of the composite material exposed between the first caul plate and the second caul plate to separate a first composite section from a second composite section; curing the first composite section and the second composite section to form a first composite part and a second composite part; and removing the first composite part and the second composite part from the layup mandrel immediately following curing.

This disclosure is directed to a thermoplastic composite material forming method and tooling used to perform the method. More specifically, this disclosure is directed to a method of fabricating large, complex thermoplastic composite part shapes with a consolidation tool having a conformable tooling bladder that heat thermoplastic material in the tool and provide thermoplastic material consolidation pressure in directions in the tool to form a part shape of thermoplastic composite material. A novel tooling concept is used to fabricate large, complex thermoplastic composite part shapes which are not easily producible using traditional methods. The tooling concept employs a consolidation tool that provides a method to apply thermoplastic material consolidation pressure by a conformable tooling bladder that provides thermoplastic material consolidation pressure in directions in the tool that are not achievable by conventional clamshell type molds where the mold parts move in substantially vertical tool opening and tool closing directions.

Systems and methods are provided for vacuum handling of composite parts. One embodiment is a method for performing vacuum securement of an object. The method includes covering the object with an impermeable membrane, locating a vacuum port at the impermeable membrane, and applying a negative pressure to the vacuum port that offsets air leaks between the impermeable membrane and the object.
