Abstract:
A foam structure includes: a first core material and a second core material that are obtained by splitting a foam body at a linear groove part, the groove part being formed in the foam body for fitting with a reinforcing material, and the reinforcing material into which the first core material and the second core material are respectively fitted from one side and the other side of the reinforcing material.
Abstract:
A system and method for fabricating a composite material assembly. The components of the assembly originate from more than one mold while providing curing or solidifying under heat and vacuum in one step only, preferably with a composite material in a pre-preg form which does not require autoclave treatment. A removable insert is removed from a second mold prior to assembly of a first mold to the second mold. A section of a laminate extending over the removable insert overlaps over an adjacent laminate after closing and assembly of the first mold onto the second mold.
Abstract:
This structure is provided with a first composite material 11, a second composite material 12 joined to the first composite material 11 by a film adhesive 21 provided between the first composite material 11 and the second composite material 12, and a corner fillet part 13 provided on a corner part 15 formed by the first composite material 11 and the second composite material 12. The shape of the corner fillet part 13 is a design shape P designed in advance, and the corner fillet part 13 is formed by curing the film adhesive 21 after arranging the film adhesive 21 on the corner part 15 so as to fit into the design shape P.
Abstract:
A method forms a butt joint between ends of first and second plies and splices the first and second plies together. The method includes the steps of: positioning a first splice edge of a first ply at a first location; positioning a second splice edge of a second ply at a second location, the second splice edge being left bare; wrapping a gum strip around the first splice edge such that the first gum strip forms a U-shaped structure in section that allows the first gum strip to extend from a first planar side of the first ply over the first splice edge to a second opposite planar side of the first ply; not wrapping a gum strip around the second splice edge; placing the first splice edge in abutting relationship to the second splice edge; and stitching the first splice edge to the second splice edge such that stitches each extend from the first planar side of the first ply, through the gum strip, to the first planar side of the second ply.
Abstract:
A connector or adhesive assembly for joining adjacent ends of insulation tubing, comprising a layer of pressure-sensitive transfer adhesive material, said layer of pressure-sensitive transfer adhesive material capable of bonding to insulation tubing, whereby when said layer of pressure-sensitive transfer adhesive material is positioned between a first section of insulation tubing and a second section of insulation tubing, said layer of pressure-sensitive transfer adhesive material bonds to both the first section of insulation tubing and the second section of insulation tubing; and a disposable release liner member adapted to hold said layer of pressure-sensitive transfer adhesive material prior to positioning said layer of pressure-sensitive transfer adhesive material between the first section of insulation tubing and the second section of insulation tubing. Generally, the seam created when the first section of insulation tubing and the second section of insulation tubing are joined is covered with tape.
Abstract:
The subject invention includes methods and apparatus for joining treads. Such methods include the step of providing a first tread portion and a second tread portion for forming a joined tread, each tread portion comprising a section of tire tread extending lengthwise from a terminal end. Additional steps include providing a first fixture configured to retain the first tread portion and a second fixture configured to retain the second tread portion and securing the first tread portion into the first fixture and securing the second tread portion into the second fixture, each of the first and second fixtures being arranged within the first and second fixtures such that the terminal end of each tread portion is in communication with a joining side of each fixture. The methods further include directing the terminal ends towards each other and into forceful engagement with an elastomeric joining material arranged between the terminal ends.
Abstract:
The present invention relates to a stretchable fabric composite. Specifically, the fabric composite comprises a first layer comprising a stretchable fabric and a second layer comprising an elastic polymer; wherein the first layer and second layer are bonded together forming the fabric composite. The fabric composite is useful for constructing a garment or a compression article. A method of making the fabric composite is also provided.
Abstract:
First and second composite members each containing first discontinuous fibers of fiber length La, are placed such that end surfaces thereof face each other at an interval of first length L1. Ends of the first and second composite members are melted over a second length L2 from the end surfaces. A connecting member containing second discontinuous fibers of fiber length Lb, is melted and placed to bridge a space between the ends, to form a stack. The stack is pressed, whereby the melted connecting member and the melted end portions flow into the space between the end surfaces to form a mixture portion. The mixture portion is cooled and solidified to produce a fiber-reinforced resin bonded body. The first length L1 is equal to or more than ½ of the fiber length Lb, and the second length L2 is equal to or more than the fiber length La.
Abstract:
In a method for producing drip irrigation tubes, a body is extruded, from which the tube is formed and in which metering elements (10) are attached, which are connected to the body by means of ultrasonic welding. For such drip irrigation tubes, the water enters the metering elements (10) from the inside of the drip irrigation tubes through inlet openings, flows through the metering elements, and exits the drip irrigation tubes through outlet openings in a metered manner. The body is formed into a tube body, which is flattened, and the metering elements (10) come to be situated in a central region inside this flattened tube body. The flat tube body is fed between a sonotrode (6) and an anvil (7) of an ultrasonic welding device (3), and the metering elements (10) are welded to the walling of the tube body. The invention further relates to a device for carrying out the method.
