Disclosed is a cover for a utility vault and a method for making such covers. The cover is formed from fiberglass reinforcement layers, a low-density core, and a polymer mix matrix. The reinforcement layers include a bottom reinforcement layer, one or more edge reinforcement layers, and a top reinforcement layer. A first portion of the edge reinforcement layer overlaps a portion of the bottom reinforcement layer and a second portion of the edge reinforcement layer overlaps a portion of the top reinforcement layer. The core is positioned between the top and bottom reinforcement layers. The reinforcement layers are formed from fiberglass fabric and may include fiberglass layers whose fibers are oriented quadraxially. The polymer mix impregnates the fabric layers, encases the core, and binds the components together. The polymer matrix includes a thermoset polymer resin.

A compression molding assembly for molding a honeycomb core, including a plurality of cells defined by a plurality of walls, of a blocker door is provided. The compression molding assembly includes a ram plate comprising a plurality of openings defined therethrough and a plurality of core inserts coupled to the ram plate such that the plurality of core inserts are configured to form the honeycomb core of the blocker door. Each core insert is removably coupled with a respective opening of the plurality of openings such that each core insert is configured to form a respective cell of the plurality of cells.

A method for making a door skin or making a door is provided. A wood board is first provided. The wood board comprises a surface having a first texture with a first plurality of grains, and at least one knot, which has a predetermined depth of crack. The surface of the wood board is scanned to obtain a first profile of the first texture. The first profile of the first texture is modified to provide a second profile of the second texture, which includes a second plurality of grains and the at least one knot. A mold comprising a metal surface is formed based on the second profile of the second texture. A door skin is molded from a polymer composite using the mold so as to provide an exterior surface having the second plurality of grains and the at least one knot.

A door skin is provided that includes at least one inner panel, an outer body portion surrounding the at least one inner panel, and at least one contoured portion surrounding the at least one panel and interconnecting the at least one panel to the outer body portion. The at least one contoured portion is recessed from the at least one panel and the outer body portion and includes a center base portion that interconnects with the outer body portion via a first sloping portion and with the panel via a second sloping portion. The first sloping portion and second sloping portions are preferably symmetrical and each of which include two bumps meeting at a vertex. The first bump is continuous with the center base portion and the second bump is continuous with either the outer body portion or the panel.

The present application provides an apparatus and a method of welding a fabric material to a frame including for removable use in a door opening or a window opening. The method includes receiving the frame having an outer edge defining an interior space at a work surface. The fabric material is then extended across the frame, so that the fabric material to be welded to the frame rests on top and covers the interior space of the frame received at the work surface. An activated welding head is then moved across the work surface and the received frame, wherein the activated welding head is moved so as to trace proximate the frame along the outer edge of the frame, thereby adhering the fabric material to the frame at the outer edge.

A method for producing a frame component for a door frame structure of an aircraft. A connecting zone is generated on a first and a second assembly surface of a connecting component in each case by generating a surface texture on the assembly surfaces, wherein the connecting component is formed from a metal material. The assembly surfaces of the connecting component are placed against a door frame member and against an attachment member, wherein the door frame member and the attachment member are each formed from a fiber-reinforced thermoplastics material. Furthermore, the connecting component and the door frame member are welded, and the connecting component and the attachment member are welded. A frame component and a door frame structure are also described.

A molding apparatus for a GRP door skin is provided. The molding apparatus is configured to form a GRP door skin of a completed product by molding a GRP door skin in a forming mold, and inserting the formed GRP door skin into a trimming removing part through a robot.

An access door for a combine harvester includes a body having a top, a bottom, a first side, and a second side. The body includes a height defined between the top and the bottom and a width defined between the first side and the second side. A plurality of ribs is integrally formed in the body for adding rigidity thereto, and a deflector is integrally formed with the body and protrudes therefrom. The deflector has a top surface and a width that is substantially the same as the width of the body. The body is defined within a first plane and the top surface is defined within a second plane such that the second plane is disposed at an angle less than 90? from the first plane.

The present invention is directed to a door facing blank having a first major surface with a design element formed therein, and an opposite second major surface. At least three longitudinally extending spaced stile receiving areas are disposed on the second major surface. Two of the stile receiving areas define a first width, and three of the stile receiving areas define a second width greater than the first width. The door facing blank may be trimmed to form a door facing having a selected width. A method of forming a door facing blank, and a mold press for forming a door facing blank are also disclosed.

A vehicular-use door comprising a first panel and a second panel bonded to a panel bonding part of the first panel, wherein the first panel is provided with a plurality of ribs, sticking out from the panel bonding part so as to cross the adhesive coated on the first panel or the second panel, along the coating direction of the adhesive, and each rib is provided with a non-visible part which is bonded to the second panel and which is covered by the second panel and can no longer be viewed from the outside and a visible part which extends from the non-visible part in a direction crossing the adhesive and which is not covered by the second panel and can be viewed from the outside.
