摘要:
Radiation shielding performs a range of functions determined by the type and number of layers of materials used, thickness, weight, and structural support afforded by the radiation shielding. A radiation shield laminate stack may be constructed consisting of a plurality of layers of ultra-high molecular weight (UHMW) polyethylene, polyethylene film, and carbon fiber, which is held together with an epoxy. The carbon fiber lay may be coated with nanoparticles of Boron (B) or Boron Nitride (BN), Boron Oxide (B2O3) or Boron Carbide (B4C) or a combination thereof to increase the shielding properties of the laminate stack. The radiation shield is lighter than aluminum, structurally sound, and thus may be used in the space environment to effectively block Galactic Cosmic Rays, atomic oxygen and UV radiation.

A strengthened polyethylene tubular member, where the polyethylene tubular member has an outer surface, a circumference, a wall thickness, an area to be strengthened, and the outer surface of the polyethylene tubular member contains polyethylene. The strengthened polyethylene tubular member contains a fabric layer wrapped around the circumference of the tubular member at least two full rotations and covering the area to be strengthened. The fabric layer contains a plurality of interwoven tape elements with a base layer of a strain oriented olefin polymer disposed between covering layers of a heat fusible olefin polymer. The tape elements within the fabric layer are bonded together and the tape elements adjacent the tubular member are bonded to the tubular member.

A manufacturing method uses a main body piece formed of an elastic fabric material and having a first portion having a first end, a second portion having a second end opposite the first end, and two side ends extending between the first and second ends. A bonding material is placed in contact with the first and/or second portions, arranged in lines extending in a direction between the first and second ends. The lines are spaced from each other in a second direction extending between the side ends. The main body piece is folded so that the first portion confronts the second portion, defining a fold line, where the bonding material is positioned between the first and second portions. The folded main body piece is then heat pressed and bent so the side ends are connected together to form a band having a tubular body defining a central passage.

The disclosure discloses a vehicle interior panel for covering an airbag and a method of fabricating a vehicle interior panel for covering an airbag. The vehicle interior panel includes a substrate with an opening, a chute channel assembly inserted into the opening, a surface skin, and a foam layer disposed between the surface skin and the substrate. The chute channel assembly includes a wall section surrounding a chute channel for the airbag and a cover plate covering the chute channel and closing the opening. The cover plate includes an airbag door, wherein an outer surface of the cover plate is in contact with the foam layer. The outer surface of the cover plate has a rough surface structure, the outer surface having a surface roughness parameter Ra of at least 4 μm.

A band includes a tubular body defining a central passage, where the tubular body is configured to be worn on a user's body such that a portion of the user's body is received in the central passage, and a housing formed of a polymer material and connected to the tubular body. The housing defines a cavity and an access opening providing access to the cavity, and the housing is configured to removably receive an electronic module in the cavity through the access opening. The housing further includes a slot in communication with the cavity, with the slot configured to permit passage of moisture away from the housing. The sides of the tubular body may also define a slope that is from 0-0.75.

The invention provides a synthetic resin container with a plurality of handgrips on its top face and a manufacturing method for such a container. The plurality of handgrips, as well as a metal cap opening, are molded in advance as insertion components. After heating the fusion portions of the insertion components, the insertion components are disposed parallel to the direction in which a parison is to be placed. Thereafter, a parison is placed into dies, and the dies are clamped. Air is blown into the parison through the metal cap opening to fuse the parison and the insertion components.
摘要:
A beverage container holder having a receptacle, gripping members, and a membrane is disclosed. The membrane is disposed in openings located between a sidewall of the receptacle and the gripping members. Living hinges are integrated into the gripping members, which allow the gripping members to flex and provide a gripping force on a beverage container that has been placed into the beverage container holder in order to provide a more stable and secure placement of the container. The receptacle and gripping members are manufactured in one step process, preferably an injection molding process, and are composed of a material having a low coefficient of friction, preferably a hard plastic, which allows for the easy placement or retrieval of a beverage container. The membrane is overmolded onto the receptacle and gripping members and is preferably composed of a flexible material such as a soft plastic or rubber.
