摘要:
A method for making a door panel, particularly for a vehicle body lining member such as a door panel, including at least one layer (1), especially a thermoplastic layer forming a core and being provided with an inner surface (2) and an outer surface (3), wherein the core layer (1) is moulded between two moulds (8, 9) while locally forming raised portions (10) that may in turn form reinforcing ribs (4) in the body of the panel; a pressurised gas is axially injected into said raised portions (10) to displace the material of said core layer (1) and thereby form tubular box beams (5); the material displaced during gas injection is deflected sideways; and at least one projection (7) is formed using said deflected material in the body of the panel.

A first elastomeric material (16) is compressed by a piston (13) to be transferred, through holes (11) formed in a dispensing plate (10) sealingly engaging the piston (13), to a plurality of recesses (8) formed in a moulding die (6), for manufacturing a plurality of plugs (5). After the material has been transferred to the forming recesses (8), the dispensing plate (10) and piston (13) are moved away from the moulding die (6) which is then lowered onto a pressure element (7) carrying a support slab (3) made from a second elastomeric material, by injection moulding. The plugs (5) are thereby applied to the support slab (3) and the slab and the plugs are then vulcanized. The plate-like element (1) thus obtained exhibits a support slab (3) on which a plurality of plugs (5) is homogeneously distributed, the material forming the plugs having physical features different from those of the material forming the slab.
摘要:
An oil film bearing for supporting a roll neck in a rolling mill, suitable in particular for transmitting high bearing forces when the bearing partners are slightly and slowly moved with respect to each other, has a bearing surface into which are incorporated rods made of a friction-reducing material (e.g., low friction compounds), which extend in a substantially perpendicular direction to the bearing surface. The rods are deformed during heat processing to define a bearing surface. The bearing partner, such as a roll sleeve, rests on the free face of the deformed rods.

Method for producing an element (1) made of composite material, the composite material comprising reinforcing fibers (112) embedded in a thermoplastic material, comprising providing a blank made of composite material, placing the blank in a mold comprising a first part and a second part defining together a molding cavity having the shape of the element to be produced, shaping the blank to the shape of the element to be produced by moving the mold in the closed position, retrieving the element from the mold in the opened position, wherein at least a compression area A of the blank is compressed between the first and second parts such that a part of the thermoplastic material of the blank is directed into at least one rib forming area of the mold cavity wherein a rib (130) is formed during the shaping of the blank.
摘要:
A spinner (15) for a fan assembly (11) of a gas turbine engine (10), a method of fabricating a spinner for a fan assembly (11) of a gas turbine engine (10), and a gas turbine engine (10) are disclosed. The fan section (11) may include a nosecap (25). The spinner (15) may include a forward end (17), an aft end (18), and a return flange (30) associated with the forward end (17). The return flange (30) may include a forward flange (34) extending forward towards the nosecap (25) and an aft flange (32) extending aft towards the aft end (18).

摘要:
A method of making products with a functional relief surface (2) with high resolution up to 10 nm, which is copied from a template (1) or carrier of the negative relief of the surface, the so-called master. The template (1) of the relief surface (2) is provided with at least one layer of geopolymer composite, applied in a precursor state (3), in form of a liquid dispersion or grout in plastic or thixotropic condition, whose thickness is the same or greater than the depth of the template relief (1), at temperatures in the interval from the temperature corresponding to properties of the precursor (3) to the temperature corresponding to thermal decomposition of the precursor (3), and after hardening of geopolymer composite the layer or layers is/are separated from the template (1).
