摘要:
A moulding material comprising a core comprising two opposing surfaces, wherein at least one of the opposing surfaces of the core is covered by a grid of continuous fibres. The moulding material may be used to form a vehicle component such as a body panel or fairing having improved strength and/or weight properties.
摘要:
A method for perforating a film of plastic material in which a main film (1) is perforated whilst it is slid through a perforating device (5) by a plurality of pressurised hot gas jets having a temperature above the melting temperature of the main film, in which the hot gas jets are correlated with the sliding speed of the main film (1), and in which reinforcing bands obtained from an auxiliary film of plastic material (2) are connected to the perforated main film (1), making the reinforcing bands adhere between parallel rows of base holes; subsequently the perforated main film (1) with the reinforcing bands is stretched in the longitudinal sliding direction. During perforating, the main film of plastic material (1) is pressed against a perforating template (22), making the main film of plastic material (1) instantaneously penetrate openings of the perforating template (22) by said hot gas jets. A hot gas perforating device (5) is also disclosed, as well as an apparatus suitable for perforating and sliding a film of plastic material according to the referred method.
摘要:
Apparatuses and methods thereof for employing impact resistant materials, pads, and layers are disclosed. Aspects of the invention include, an impact resistant material including an elastomer material having a base layer and a plurality of raised portions extending upward from the base layer, wherein each of the plurality of raised portions has a top surface and at least three primary sides. Each of the at least three primary sides having a middle region positioned closer to a center of the respective raised portion than either end region of the respective primary side.
摘要:
A self-transforming structure is formed from a flexible, fibrous composite having a weave pattern of fibers woven at intersecting angles, the weave pattern having a boundary and one or more axes for the fibers, and an added material coupled to the flexible, fibrous composite to form a structure, wherein the flexible, fibrous composite and the added material have different expansion or contraction rates in response to an external stimulus to cause the structure to self- transform, and wherein the added material has a grain pattern oriented relative the weave pattern of the flexible, fibrous composite. Applications of the self-transforming structures include aviation, automotive, apparel / footwear, furniture, and building materials. One particular example is for providing adaptive control of fluid flow, such as in a jet engine air inlet.
摘要:
A method includes providing an open weave fiber glass scrim ( 102 ), and printing a discontinuous pattern of an ethylene vinyl acetate (EVA) hot melt adhesive ( 108 ) on a major surface of the open weave fiber glass scrim, the adhesive having sufficient viscosity at an application temperature used during the printing step to avoid wicking through the scrim.
摘要:
In some examples, the disclosure relates to a fabric assembly comprising a flexible substrate including a top surface; a plurality of plates affixed to the top surface of the flexible substrate and arrayed in a pattern such that a plurality of continuous gaps are defined between adjacent plates; and a coating formed on at least one of the substrate and plurality of guard plates, wherein the coating is selected to increase at least one of scuff resistance, oil resistance, water resistance, stain resistance of the fabric assembly.
摘要:
Retroreflective vulcanized rubber articles with retroreflective sheeting bonded to it are provided. The retroreflective sheeting contains a plurality of retroreflective elements at least partially embedded in a polyurethane binder layer.

摘要:
A tile unit (10) is provided, comprising a tile adhering sheet (5) comprising a heat-activatable adhesive resin layer, and a plurality of tiles (7) having front surfaces, the tile adhering sheet being heat-activatably adhered to the front faces of the tiles by the heat-activatable adhesive resin layer. Also, a tile adhering sheet is provided, comprising a heat-activatable adhesive resin layer, whereby the surface of the tile adhering sheet has a surface which can partially heat-activatably adhere a tile. Furthermore, a method of installing tiles is provided, comprising the steps of coating a tile bonding mortar or adhesive on a surface where tiles are to be installed; applying the tile unit above to the surface coated with the tile boding mortar or adhesive to at least partially cure the tile bonding mortar or adhesive; and separating the tile adhering sheet from the tiles.
