Abstract:
The present invention discloses an apparatus for producing a pressure vessel blank (2) comprising at least one connection element (7), the apparatus having the following features: - the apparatus comprises a multi-part blow-moulding tool with at least two blow-mould halves (10), which in each case have a partial cavity (11) and between which a tubular preform (9) consisting of thermoplastic material can be positioned in an open position of the blow-mould halves (10); - the blow-mould halves (10) can be made to move between an open position, in which the blow-mould halves (10) are apart from one another, and a closed position, in which the blow-mould halves (10) are in contact with one another, the partial cavities (11) forming in the closed position a mould impression in which the preform (9) can be moulded to form the pressure vessel blank (2) by means of applying differential pressure; - the apparatus comprises at least one blowing pin (20), which has a gas outlet opening (22), arranged in an end portion (21) of the blowing pin (20), for discharging a gas and a holding device (26) for releasably holding the connection element (7), the end portion (21) of the blowing pin (20) being insertable into a through-passage (7a) of the connection element (7); and - the blowing pin (20) can be positioned between the blow-mould halves (10), so that in the closed position of the blow-mould halves (10) the preform (9) positioned between them can be moulded in the mould impression while being brought to bear against the connection element (7) by application of gas pressure by way of the gas outlet opening (22). The apparatus is characterized in that the blowing pin (20) has a fluid outlet (23), arranged in the end portion (21), for discharging a cooling fluid and a fluid inlet (24), arranged in the end portion (21), for receiving the cooling fluid, and in that the fluid outlet (23) and the fluid inlet (24) are in fluidic connection with one another, so that the through- passage (7a) of a connection element (7) held by the blowing pin (20) can be brought directly into contact with the cooling fluid and a cooling fluid circulation can be produced in the through-passage (7a) of the connection element (7).
Abstract:
A seat back assembly that includes a composite seat back cover. The composite seat back cover includes at least one composite layer, that includes a layer of reinforcing fibers and a thermoplastic layer surrounding the reinforcing fibers. The thermoplastic layer is coextensive with the layer of reinforcing fibers. In various embodiments, the seat back includes a seat back frame. The seat back frame includes a side rail, a top rail main section, and a top rail cap. The side rail, the top rail main section, and the top rail cap are fused to each other by a homogenous chemical bond. A homogenous chemical bond is formed between the seat back cover and the seat back frame creating a unitary seat back assembly.
Abstract:
The present invention relates to a method of manufacturing a thermoplastic product in a mould comprising at least two opposing mould parts defining a cavity to at least one of press mould and injection mould the product from thermoplastic material. The method comprises providing a fiber reinforced sheet of a fiber fabric encapsulated in a thermoplastic resin, forming the fiber reinforced sheet in correspondence with a shape of the product and arranging the formed fiber reinforced sheet on and connected close fittingly to an outer surface of the product. The method further entails dividing the fiber reinforced sheet in portions in shape optimized for low cut losses, said shapes being from the group at least comprising rectangles, squares and honeycomb or six-cornered shapes, and welding two or more fiber reinforced sheets or portions thereof together, prior to forming the combined fiber reinforced sheet in correspondence with a shape of the product. Further more the invention relates to a product, comprising a layer of thermoplastic material and a reinforcement, wherein the reinforcement comprises at least one fiber reinforced sheet and is arranged on and connected close fittingly to an outer surface of the layer.
Abstract:
A failure module includes a support element. A reinforcing element is disposed on the support element. The support element is chemically compatible with the reinforcing element. A homogeneous chemical bond is formed between the support element and the reinforcing element.
